Periodic Report Summary 2 - R3WATER (Demonstration of innovative solutions for Reuse of water, Recovery of valuables and Resource efficiency in urban wastewater treatment)

Project Context and Objectives:
So far, municipal wastewater treatment plants are usually operated to efficiently achieve emission targets. Current research and development shows that these plants can be upgraded into production units, i.e. to provide energy, nutrients, water for re-use and possibly other valuables. This can be achieved by improved resource efficiency in the plant as well as by implementing new technologies and business models that allow the re-use of both treated wastewater and resources in the influent wastewater.

The main objective of R3Water is to demonstrate solutions that support the transition from a treatment plant for urban wastewater into a production unit of different valuables.

The technologies included in R3Water are categorised according to three different targets; Reuse of water (to produce a water that can be reused for eg. irrigation purposes), Resource efficiency (saving energy by treating the wastewater in a more resource efficient way) and Recycling of valuables (recovery of eg. phosphorus from sludge and sludge ash). In order to reach these 3 targets, a number of different technologies are being developed and demonstrated at three demonstration sites, located in Spain, Sweden and Belgium. In total, 6 technologies will be demonstrated in Spain, 7 in Belgium and 8 in Sweden.

The possible impacts of the project after successful implementation of the technologies include:
• Reduction of the energy consumption by 15% with new technologies and control solutions for process operation
• Increase the energy production (biogas production) by 10% with new technologies and control solutions for process operation
• Recover water from the wastewater treatment process and therefore minimise the environmental impact of the remaining effluent by 10-20% lower emissions of nitrogen, phosphorous, COD, and other priority substances
• Safer water supply in regions with water scarcity due to quality assured water re-use
• Turn the waste problem connected to the handling of the produced sludge into a recovered valuable raw material in terms of products that can be readily put on the market and by that giving income to the production plant

During the 2nd reporting period, which covers M19-36 of the project period, a large focus has been put on demonstrating the different wastewater treatment technologies at the different demonstration sites located in Spain, Belgium and Sweden. By the end of the 2nd reporting period, most technologies have been installed and are currently running a demonstration, or have already completed the demonstration. Only a few technologies remain are still in demonstration by the end of the 2nd reporting period.

A lot of optimisation of demonstrated technologies has been conducted during the 2nd reporting period. The demonstration phase was used to show the technologies in operation as well as to optimise performance or test for different conditions in order to facilitate continuous operation of the technology in real-life wastewater treatment plant conditions.

Apart from demonstration and optimisation of technologies, 2 workshops have been organised during the reporting period “From Innovation to Market: The Second Valley of Death” in Leeuwarden, The Netherlands, in February 2016 and “Innovations for water reuse, valuables recovery and resource efficiency” in Barcelona, Spain, in November 2016. Both workshops were arranged in connection to other related events resulting in a high participant presence. In connection to the workshop arranged in Spain, a day of site visits was also offered to the participants. During this day, a total of four Spanish wastewater treatment plants demonstrating R3Water technologies were visited.

A first brochure presenting the first results of the project was published in November 2015. It will be followed up with a 2nd brochure by the end of the project, presenting the actual project results. A 2nd newsletter has also been published during the reporting period. All flyers, brochures and newsletters can be found at the R3Water website (www.r3water.eu).

Three R3Water technologies have been selected to, within the project; carry out the EU Environmental Technology Verification (ETV) programme. One of the technologies; AQUATRACK™, completed the verification procedure in autumn 2016. The technology was also awarded the WssTP Water Innovation Award 2016. The two remaining technologies; the HTC and aquaBio technologies continue the process in the EU ETV programme.

The R3Water project is co-funded by the European Commission under the Framework Programme 7. The 42month long project started in January, with a total budget of 7.8 M€. The consortium, which is coordinated by IVL Swedish Environmental Research Institute, unites 12 technological partners from 7 European countries with involvement of SMEs and RTD centres, amongst others.

Project Results:
Within R3Water, demonstration of innovative technologies in the areas of water reuse, resource-efficiency and resource recovery for municipal wastewater treatment are the key element in order to support implementation and market access of these solutions. After 36 months of the project, most of the planned work has been performed.
All technologies have been or are under demonstration, several technologies at each of the three demo-sites. Additional optimisation work based on results from the demonstration has taken place. The technologies and solutions demonstrated include:
Water re-use: disinfection, monitoring, removal of pharmaceutical residues
Resource recovery: sludge treatment by HTC, ash treatment system solution
Resource efficiency: improved aeration, improved biogas production, efficient Anammox process, control with specific sensor, model predictive control, plant wide modelling.

Market studies for the technologies in each of these areas have been performed. Three technology verifications according to the EU-ETV scheme have been started and one (Aqua-Q) has been finished successfully.
Dissemination work has been performed at different levels: Site visits to show the different technologies, brochure and newsletters, 3 workshops at different locations, a website that is updated with news, information posted on LinkedIn. Furthermore, connection with the EIP Water and relevant groups has been established as well as contact to other projects.
For organisation of the project, adminstrative, financial and risk management was part of the work performed.

Potential Impact:
The possible impacts of the project after successful implementation of the technologies include benefits for the improvement of municipal wastewater treatment, the mostly used biotechnological process:
• Reduction of the energy consumption with new technologies and control solutions for process operation
• Increased energy production (biogas production) with new technologies and control solutions for process operation
• Recover water from the wastewater treatment process and therefore minimise the environmental impact of the remaining effluent by 10-20% lower emissions of nitrogen, phosphorous, COD, and other priority substances
• Safer water supply in regions with water scarcity due to quality assured water re-use
• Turn the waste problem connected to the handling of the produced sludge into a recovered valuable raw material in terms of products that can be readily put on the market and by that giving income to the production plant
