DEVICE FOR LARGE SCALE FOG DECONTAMINATION

Final Report Summary - COUNTERFOG (DEVICE FOR LARGE SCALE FOG DECONTAMINATION)

Executive Summary:
Chemical, biological, radiological and nuclear events are a serious risk for humanity. These include natural, accidental and deliberated man-made threats severely affecting human health as well as the environment in a large scale.
A multidisciplinary team of 10 institutions from Spain, UK, Sweden, Germany, Czech Republic and Bulgaria has developed from scratch up to TRL6 a new intrinsically environmental-friendly and electric-compatible technology to quickly counteract these agents called COUNTERFOG.
Counterfog is additionally simple and economical. It esentially uses a jet of micron-sized water fog specifically optimized to decontaminate the air, removing all kind of noxious air borne particles –including spores or radioactive particles.
This team engineered a nozzle able to provide a very especial fog and a laboratory to test the system under strict ethical, environmental, Health and safety control. At the micron scale particle size and air viscosity are determinant of the whole process. Counterfog water droplets aggregate and remove air borne particles quite efficiently. Counterfog has demonstrated to remove biological aerosols or radiactive particulates from air in the laboratory in less than a minute.
Additionally, counterfog nozzles can provide a fog enriched with catalytic nanostructured microparticles to decompose a broad range of chemical agents. Toxicity tests carried out with cells, zebra fish embryos and mice show that counterfog is completely harmless for health and environment.
COUNTERFOG has been demonstrated in large scale tests removing 99% of air borne particles from a large atrium in a few minutes. Finally a prototype on board of a truck was developed and tested showing a unique feature: the ability to absorb and clean smoke.
As a side appplication of counterfog it has demonstrated to be able to remove traffic generated air borne particles that are a problem in modern cities and generate pulmonary diseases. Tests in laboratory prove that the application of 1 min of counterfog reduces PM10 (under 10 micron particles) in two orders of magnitude.
Starting from zero, COUNTERFOG has achieved a trl 6 demonstrating effectiveness in relevant environment and it is ready to be demonstrated in operational environment in a near future.

Project Context and Objectives:
Chemical, Biological, Radiological and Nuclear episodes are a continuous risk for Society. Accidental or deliberated releases of CBRN agents may seriously affect health and lives of a large number of people. A common property of these agents is their dispersed state in air.
Current decontamination methods are complex, expensive and time-consuming what makes them unaffordable in case of massive events or large number of people affected.
The main objective of this project is to design, build and test a rapid response system for collapsing all kinds of dispersed agents (smoke, fog, etc.) by using a fog made of a solution that could eventually also contain any kind of neutralizing component. We call this a “COUNTERFOG”.
It is intended to be installed in large public buildings like railway stations, airports or stadiums. A portable COUNTERFOG for use outdoors was also an objective. Counterfog is intended to counteract any accidental or intentioned release of pollutants or noxious substances in its earliest stages, greatly reducing the number of potential fatalities.
COUNTERFOG strategy is to use a dispersed state with a large surface/volume ratio suitable to penetrate all the intricate holes agents are able to infiltrate. Requiring a minimum quantity of decontaminant, it is intrinsically environmental-friendly and electric-compatible. The main targeted benefit is to neutralize and collapse the noxious cloud. Additionally, preventing the dispersion of agents in air it is expected to help minimizing the effects of CBRN agents on the affected people in that area, and finally, to help to rapidly decontaminate any equipment and the facility itself.
The main objective is therefore to provide a system or device to physically collapse any dispersed product –i.e. fog, cloud or smoke- .
To achieve this goal a series of specific objectives have been targeted as follows:
- To design and build a prototype of Nozzle capable of the performances required for the Counterfog.
- To design, build and set ready a laboratory for experimental study of fog dynamics and the effects of the counterfog nozzle under different conditions.
- To determine the best solution and products for decontamination –exclusively of surrogates- as well as to determine the fog dynamics in laboratory conditions.
- To design and build a portable on truck.
- To install a fixed counterfog in a real large building and to test the fog dynamics produced by it.
- To test the fog dynamics in an open air environment with the portable on-truck prototype.

Project Results:
The main result of this project is the development of a unique technology to decontaminate air suitable for a broad range of CBRN agents. It has been demonstrated in relevant environment with surrogates as well as smoke.
For RN surrogates this demonstration can be taken as enough –as long as the physics involved is the same as for the real agents-. For Biological and Chemical, a good rational basis has been established to expect effectiveness against real agents. However tests with real agents would be required for a full qualification of the system.

Physics of Fog interaction
The physics of interaction of droplets and particles with air has been explored both theoretically and experimentally with interesting and somehow surprising results. It was demonstrated that aggregation of particles with water droplets was strongly dependent on the droplet size and the optimal size of droplet was determined. Laws for evaporation and falling down were derived and experimentally verified.
Eventually it was demonstrated that the unique cone of fog created by the Counterfog nozzle provides the optimal dynamics conditions –particularly velocity gradient- for an effective and efficient aggregation of droplets and particles. Fogs cones of Counterfog are quite suitable to wash out particles or micron sized droplets.
Engineering and development of Counterfog Nozzle
There are many nozzles to create mist or fogs. 14 types of atomization principles were investigated, 22 nozzles among 70,000 models from 21 manufactures were collected, and 35 cutting-edge patent nozzle designs were investigated. However none of them was able to provide the optimal size at a flow rate suitable for the treatment of building-size volumes.
2 out of these 6 nozzle designs concepts were selected for the COUNTERFOG nozzle design. A new nozzle was engineered to provide a flow rate up to 125 l/min with an optimal droplet size using Finite elements/controlled volumes computer models.
38 design parameters for 9 different nozzle dimensions were studied. 11 sets of operating pressures and 11 sets of fluid properties were studied to investigate the performance of nozzle at different working conditions with different fluids.
It was built, tested and the results were fed back to reengineer and develop the unique optimized Counterfog nozzle. Critical parts of the nozzle were manufactured in ceramic materials. Nozzles were redesigned considering difficulties in machining, assembly and sealing. The nozzle were scaled down to 1/2 and a 1/4 of the original size. Performance of these redesigned nozzles were evaluated.
The nozzle modified 1/2 is able to fog the third component (which can be nanostructured particles, hydrogen peroxide, etc....) simultaneously to water.
Fogs Dynamics Laboratory
A laboratory for experimental tests of fog dynamics and interaction, as well as decontamination with surrogates has been designed, built, characterized and set up, being an asset for further research. This laboratory is provided with two thermally controlled chambers of 15 m3 each –conectable through a door and primary protection systems for protection of environment and staff from agent surrogates (air filtration and waste collection).
The particular characteristics of the laboratory -in which temperature and humidity are controlled and thermal gradient on the walls is minimized- allow exploring the fog dynamics and interaction of dispersed matter under unique conditions.
The distribution of the fog in the laboratory was measured to be homogeneous.
SPCE sensor
A new kind of sensor based on Surface Photocharge Effect has been developed, using a liquid interface to measure the presence of pollution or agents in the air. Tests in laboratory with surrogates demonstrate a high sensitivity to the surrogates. More experimetns with real agents and false ones would be needed to mature the sensor.
A second sensor was developed to measure anomalies on surfaces –with potential application to the measurement of the degree of contamination of a surface.

Portable Counterfog
The installation of a portable on board of a truck Counterfog prototype was completed. Even more it was tested and assessed and a fully redesign was done in order to better fit to the end-users advice and expected performance. A new version of the portable Counterfog was then designed, installed and tested. This new version has three possible configurations: One is a portable 1:2 nozzle fed by hoses from the truck to be handled by a user; the second one is a 1:1 nozzle held on top of the crane of the truck; the third one is a deployable set of 10 1:2 nozzles.
The portable nozzle would be used for manual control of concentrated sources of smoke or toxic spills in industries, as well that for dissemination of nanostructured micro particles as a third component to counteract a chemical agent. Additionally the portable nozzle may be used for disinfection of surfaces when providing hydrogen peroxide. Max water flow: 0.4 l/s. Nominal water flow 0.2 l/s. Nominal air flow: 25 n.l/s. Max air flow: 35 n.l/s.
The 1:1 nozzle held on top of the truck is intended to capture smoke or toxic gases emerging from a concentrated source (i.e. spill). Max water flow: 4.0 l/s. Nominal water flow 2.0 l/s. Nominal air flow: 250 n.l/s. Max air flow: 350 n.l/s.
The deployable set of 10 1:2 nozzles is intended to be used to create fog barriers to “encapsulate” CBRN or smoke sources or fire. Max water flow: 4.0 l/s. Nominal water flow 2.0 l/s. Nominal air flow: 250 n.l/s. Max air flow: 350 n.l/s.
All the three configurations present a control, attenuation and extinguishing capability. For example, the configuration of 10 nozzles leads to an extinction capability of 2166 kW.

Air decontamination in laboratory
Fog dynamics and removing of CBRN surrogates from air in laboratory were completed and extended to measure surface decontamination capability.
The main features of fog dynamics for several COUNTERFOG nozzle working parameters were determined and those optimal were found. This was a systematic slow exploration work that required careful analysis and observation but led to a quite fruitful result. B1/2 nozzles with defined air and water pressure supplies both under 15 bar provide a dense fog with droplets sized between 5 – 10 µm that is able to clean simulants of C,B and RN agents –in some cases the addition of 1% isopropanol is required-. This was decided the best choice for cleaning solutions for its environmental friendly properties and harmlessness. The dispersion of nanostructured TiO2 micro-particles -as a component in the Counterfog acting as catalysts and absorbers- prior to the application of a final fog has proved to be quite effective against C simulants.
Moreover, Counterfog is able to decontaminate smoke reducing the number of 10 and 5 µm particles in air to levels even lower than those existing currently in the air of Madrid. This means that Counterfog even removes the atmospheric solid particles pollution of air.
Surrogates used included talcum, sodium bycarbonathe, CsCl, KH2PO4, urea and iodine for RN; methyl salicylate, DPGME and TEP for C; and Bacillus Thurigiensis for B agents.
Chemical surrogates can be removed from air and partially from surfaces (depending on porosity), in some cases using just water and in others releasing the nanostructured TiO2 microparticles.
Spores and bacteria aerosols can be washed out from air using just water. It can be concluded that even increasing the number of spores in the air, a 99 % of reduction is archived with a shot of 30 s and 96 % with a shot of 15 s
RN simulant Hydrophilic powder suspensions are easily removed by water fogs. Hydrophobic powder suspensions need the addition of some surfactant to allow wash out.
Surface C decontamination
An additional feature of Counterfog is that is also able to decontaminate surfaces in addition to air. The decontamination capability depends on the position of the surfaces and their porosity
PVC is cleaned effectively and to a greater extent in those samples located in front of the nozzle, where the fog reached directly.
Wood: wood samples decontamination depends in the positions were the coupons were placed. In the cases where the reduction was lower, the reduction is about half after the fog. Probably the strong and direct incidence of fog has promoted the penetration of the solubilized compound in the porous surface of wood being retained into the sample.
Concrete: for this material all samples have around 80% less contamination than the reference sample. Cleaning reached is regular in all positions. At this point it should be mentioned that between the one of the main components of concrete is calcium hydroxide (Ca(OH)2). In presence of moisture this compound will dissociate.
Based on results obtained, it can be concluded that the effect of fog on contamined surfaces mainly depends on two factors, the porosity of material surface and hydrophobicity of surrogates. The cleaning capacity of the fog is greater in low or non porous materials and when the pollutants are hydrophilic. With hydrophobic simulants, although it has been proven that the fog with surfactant cleans the laboratory atmosphere, it cannot effectively remove agents deposited on exposed porous surfaces.
Surface B decontamination
Hydrogen peroxide has proved to be the best option for disinfectants to be used with bacillus Turighiensis. Porous and non-porous surfaces can be disinfected using a H2O2 Counterfog.
It is demonstrated that the Counterfog handheld portable nozzle is suitable for surface decontamination in a real scenario including furniture and the inner surface of venting conduits.
Although the objective of this test was not to establish a full procedure, it is clear that an operational procedure should consider “shadows” as that formed under the desk –quite comparable to that in the drawer-.
The fog demonstrates to be able to penetrate intricate holes when properly applied.
Electrical compatibility
Additionally, electrical compatibility tests were done showing that a few electronic devices still work after Counterfog activation. Most of the pieces of office hardware work after repeated application of Counterfog.
Conventional office hardware not particularly prepared to withstand wet environments survived repeatedly the application of Counterfog with water, nanostructured TiO2 micro-particles and hydrogen peroxide. Some of these applications were direct and profuse. Even if they showed droplets on their surface they still remained working –except for the case of the keyboard that filled up of water. We can assume that the penetration of the fog –particularly when applied directly- should be at least as effective as the penetration of any agent dispersed.
Large scale tests: barriers, fire and smoke
The system was tested in a large building and in open field conditions. A fixed Counterfog installation has demonstrated to be able to generate fogs similar to those in the laboratory. A scaling of the product “number of nozzles x activation time” proportional to the “total volume” in the atrium works reasonably similar to that in laboratory.
It has been demonstrated that the thick droplet Counterfog cones are effective eliminating solid particles (background level) especially those sized 5 and 10 µm. This mechanism seems to be much more effective than that of gravitational fall down. If the whole volume of air circulates through these surfaces particles are significantly eliminated.
It was demonstrated that the fixed Counterfog system installed in a building was able to remove microparticles (including the RN surrogates) from air as it does in the laboratory. The use of nanostructured TiO2 micro-particles was also demonstrated to be effective against Chemical agents surrogates in the large building as it was in the laboratory.
From the bicarbonate and talcum (used as RN simulants) tests it can be concluded that the wash out of particles both in hydrophilic and hydrophobic cases scale from those of laboratory. Reductions of 99.7 and 87.2 % are achieved with just 6 min of 9 1:2 nozzles activation. 1% Isopropanol is required for the hydrophobic case.
According to the results of the tests with particles, the use of just 9 nozzles for the RN simulant tests was a handicapped case. The correct number of nozzles activated for the volume of the atrium where tests where performed (1443 m3) should be 13 1:2 nozzles actuating for 6 min. This should improve the results and make deeper decrease of the floating mass
The application of a small amount of a dispersion of nanostructured TiO2 micro-particles in water from the third component vessel of the Counterfog portable nozzle was able to reduce the Chemical simulant Methyl Salicylate in more than 80% in 5 min demonstrating catalytic activity in air -easily scalable to get higher decontamination ratios-. The subsequent application of a water Counterfog using the fixed system provided a motion of the already deposited –but not yet decomposed- simulant making it easier to decompose and the decontamination deeper than expected.
Ethics constraints to the dispersion of biological surrogates made it difficult to make quantitative tests for the Biological surrogates in large scale. Qualitative tests with the natural microbes present in the large building are indicative that Counterfog is able to remove biological air borne “particles” –including yeast, fungi, spores and bacteria-. A limited application of the 10 nozzle system (although not covering the whole surface) is able to sustainably decrease the number of air borne microbiological material (spores, bacteria, fungi, yeast...) floating in air. This is a qualitative step as this air borne microbes were not part of liquid droplets in a aerosol but in their natural state.
The system demonstrated the ability to wash out Smoke and a certain capability for control or suppression of fire similar to other fog based fire protection systems. The Counterfog cone is able to capture both hot and cold smoke. Additionally the three configurations show a control, mitigation and/or extinction capability in a good correspondence to the theoretical model proposed to calculate.
Outdoors tests fulfilled it smain objective demonstrating that Counterfog can create reasonably effective barriers to the progress of “toxic” clouds. Although ethics restrictions to outdoor tests affected Biological and Chemical surrogates as well to nanostructured microparticles, tests with RN surrogates and smoke were enough to demonstrate the physics of absortion and curtain or barrier effects. As long as it is just physics involved, it is therefore possible and reasonable to extrapolate the results of the laboratory with all CBRN surrogates taking into account the new boundary conditions –i.e. wind-.
Soot trapped by Counterfog droplets is intensively deposited onto surfaces and floor avoiding propagation and contamination of other areas.
A set of 10 Counterfog nozzles forms an effective barrier against fire, heat, cold smoke and warm smoke. The analysis of smoke plume demonstrates smoke reductions through higher than 77%.
There is a cooperative additive effect of nozzles that is achieved in parallel configuration. Fog dynamics is much effective when several nozzles cooperate in the same direction.
Tests 10 demonstrated the extinguishing capability of Counterfog. Although it is not its primary purpose, it has capability to control, attenuate and extinguish fire with a total available suppression nominal power of 214 kW per 1:2 nozzle.
Additionally, some more tests of washing out of traffic-related smoke have been also carried out. Smoke is one of the more ubiquitous pollutants and can be associated to a real scenario in which fire and explosion can be combined with agents. Several ways of integration with fire protection installation have been proposed, being the smoke barrier the preferred by end-users.
As a conclusion the large scale tests have demonstrated that Counterfog can be used as a fast countermeasure to protect facilities, infrastructures and human lives against CBRN episodes in their most early stages.


Compatibility of Water and TiO2 nanostructured microparticles catalyzer
Although they were not planned in the DoW, VVU carried out new tests of decontamination of real agents with these particles in presence of water finding that water did not affect the action of these catalyzers. Nanostructured TiO2 microparticles have demonstrated to be effective against real C agents inpresence of water.

Harmlessness of Counterfog
Absence of harmfulness of the water fogs as well as the best additives and nanostructured TiO2 microparticles has been demonstrated with zebra fish embryos and Human Cela tests as well as mice in the short term. In long term tests with mice no significant damage has been detected.
The aim was to find out the possible negative effects of different ‘relatively non-toxic’ compounds administrated in a fog on the functioning of the respiratory systems of animals through the measurement of the blood oxygen saturation and histopathology of the animal's lungs. The results were collected both in a short-term and a longer one year study after exposure.
A non-invasive method for measuring blood oxygen saturation (SO2) was used in all animals during both types of experiments and histopathology of the lungs was performed at the end to determine any possible detrimental changes due to the fog.
Any product used in fog way during the studies had no relevant negative effects on the blood oxygen saturation percentage in any animal. This showed that the respiratory capacity of animals was not affected in the short or the long-term studies.
Deaths during the long-term studies were not related to the inhalation of the fog products.
A slight degree of lesions found in lung histopathology and its presence in the Naïve control group, suggest a lack of association with any fog treatment in the short term.
More lesions appear in the long term lung histopathology but still in such a small number that it is difficult to correlate to the use of substances. They appear in the just water fog group as well.

Potential Impact:
The main impact of Counterfog will be the increase of resilience, safety and security against CBRN episodes as well as protection of the environment in CBRN and in fire events. These include natural and accidental and deliberated man-made threats severely affecting human health as well as the environment in a large scale.
CBRN episodes appear often. Just to mention for example the most recent, London City airport was evacuated on October 2016 in chemical scare; Hamburg airport was evacuated in February 2017; smoke from a tyre dump fire in Seseña (Spain) forced evacuation of several thousand people...
Chemical leakages from industry or transport means are even more common: Sussex 2017, Igualada (Spain) Feb 2015, Humanes (Spain) sep 2017...
Anthrax spores were used by terrorists and the use of CBRN warfare agents by terrorist groups is always a threat.
Counterfog, being simple, easy and non-expensive to install and maintain can provide a safe counteracting technology able to reduce damages and severity as well as to shorten the time to recover installations –preventing contamination-.
Additionally, it can be used to remove solid particles from air including those from Diesel engines and heating systems. According to the report “Non-exhaust traffic related emissions. Brake and tyre wear PM” of the Joint Research Centre of the European Commission 2014 these particles affect several million people in Europe generating cardiovascular and respiratory diseases as well as lung cancer. They enhance early artheriosclerosis –due to the high content in redox chemicals and their reactivity among others.
Counterfog provides a tool to quickly counteract the dispersion of agents in air. The effects are therefore beneficial for health and human lives, environment and economy.
Although there are many different scenarios in which the technology could potentially be applied with different final solutions and the triggering mechanism is to be discussed the following classification was done according to:
Type of contaminant (CBRN or smoke)
Space (Closed, semi-pen, defined open, open)
Type of origin (Concentrated, Focused, dispersed)
In the Business plan the next situations were identified with the need of a Counterfog:
• CBRN event in critical infrastructure,
• Air pollution crisis and Air pollution control protocol activation for air quality improvement
• Fire. Industry accident, dangerous good transportation accidents and similar events
• Other kind of accidents or crisis with big air emissions with potential health and environmental consequences
Therefore, the type of events can be generally described as crisis prevention of scenarios in which there are air emissions of pollutants or other kind of hazardous gases or suspended agents
These events can take place in:
• Closed but regular spaces ( indoor)
• Closed but big spaces (buildings, airports, railway stations...). Particularly in critical facilities (indoor)
• Semi-open spaces such as football stadiums or similar
• Defined open spaces: open areas but defined in the sense that a certain area is the relevant for the intervention. For example in city areas in which there is higher concentration of pollutants
• Fully open spaces
Also the events can be understood as having a Concentrated, Focused, and Dispersed origin:
• Concentrated origin: a smokestack, chimney or funnel discharging smoke or other pollutants from locomotive, factories or similar. The origin is an engine or similar and the emission has been concentrated to be expulsed trough an exhaust, chimney smokestack or similar
• Concentrated origin: as an accident involving hazardous products, a fire in a facility or a CBRN bomb in a critical infrastructure
• Dispersed origin: the pollutant, spore or agent is generally dispersed in the air
In conclusion Counterfog can be used to clean pollutants, CBRN emissions and other agents dispersed in the air being especially relevant for Semi-open to open spaces and for focused but not concentrated emissions or dispersed presence of those elements.
In each situation COUNTERFOG could be applied as a countermeasure using the fix installation or the portable (on-truck/truck connected or individual device). Obviously this gives place to a spillover of possible applications, mainly the following: Smokestack, funnel discharging CBRN attack in an airport, CBRN in a stadium, CBRN event in a square, CBRN bomb decontamination activity, Hazardous products transport accident or general smoke.
Integration in fire protection can go further than intercommunication with fire control unit, including the use of the same source of water provided it is free of Legionella. However, this does not preclude the need of the compressed air pipeline and therefore does not produces a great impact on the cost of installation.
Additionally Counterfog has a limited fire suppression capacity as any other water mist device. The particularity of Counterfog comes from the fact that does not require high pressure to provide a large flow of fog. However, as the amount of water used is small the extinction power –that can be easily calculated- is also limited.
However, a more striking firefighting potential of Counterfog is related to smoke control. Counterfog could be used in different ways to remove smoke with some advantages, being the smoke barrier the preferred by end-users.
For instance, a Counterfog nozzle pointing outside extracts smoke from behind. Counterfog water droplets will capture polluted particles and collapse them into the ground and other surfaces preventing the smoke to pollute the environment.
IP protection was completed in the form of a 8 patent applications (European, Spain and Bulgaria) and extensions of three of them to PCT or USA. Once it was ensured that novelty was not to be spoiled, dissemination activities were intensively carried out in several ways: 14 peer reviewed journal papers or book chapters, 18 papers in proceedings of conferences, 1 section of a book, 1 doctoral thesis (three more are in progress), 2 monographs, organization of two conferences and a workshop, 30 presentations in 14 conferences, 2 national TV short reviews in Spain and Bulgaria, web page and a demonstration workshop. A paper by Juan Sánchez (UAH) was awarded best poster in the Rome CBRN conference in May 2017. Kiril Angelov (BAS) won the “best paper” award at the Annual Conference of the University of Rousse, 9-10 October 2015 for the work Methodology for Assessing Spray Droplet Diameter Distributions.
Counterfog has appeared in the National TV channels in Spain and Bulgaria: TVE1 in Spain and Channel 1 of the Bulgarian National Television and a video clip has been created. A subtitled version of the TVE1 emission (July 17th 2017) can be found at https://youtu.be/-egCrFQxnFs
The share at the time it was broadcasted was 150,000 people.
The Bulgarian National TV emission (Nov 27 2017) can be found at: https://www.bnt.bg/bg/a/svmestna-razrabotka-na-sistemi-za-zashchita-pri-bedstviya-i-ataki
Additionally a video clip has been created for dissemination that is available in youtube: https://youtu.be/5jkfpAwXTAI
In the workshop organized to demonstrate Counterfog there were present more than 100 attendees from France, Germany, Portugal and Italy including first responders, policy makers, governments, army, city councils, civil protection, international organizations and companies.
Feedback from CBRN stakeholders and more specifically from first responders was used to improve the business and exploitation plan. The business plan obtained two awards: an internal award to best idea for creation of a Technological based company by UAH; and a similar external accesit given by the Madri+d foundation for knowledge. A spin-off company called “COUNTERFOG EBT de la UAH SL” is in process to be incorporated in order to exploit the results most effectively with a very good prospective according to the created Business plan.
The domain www.counterfog.eu was registered and Counterfog web was created as a showcase of the Project objectives and main advances always under the restriction imposed by IP protection and Security. Twitter and LinkedIn accounts have also been recently created in order to make Counterfog Project results more accessible to a more specialized public.
Additionally a few activities of dissemination to general public and secondary schools have been done, particularly in the week of science 2017.
A demonstration with UME in the Torrejón Air Base was followed in live by TV channels : ANTENA 3, LA SEXTA, LA CUATRO, TELEMADRID; radio: RNE, COPE, ONDA MADRID and SER as well as press: LA RAZON, ABC, 5 DIAS, etc as well as agencies

The plan for further dissemination of the project has planned four activities:
- Publication of papers currently in preparation
- Presentations in conferences –in security, environment, sensors...
- Meetings with first adopters and case demonstrations
- Promotion of youtube video and social networks.
