Development of Advanced Wastewater Treatment with Ozone Oxidation and Flotation Technique for Maximum Water Reuse

Final Report Summary - ADOXPOL (Development of Advanced Wastewater Treatment with Ozone Oxidation and Flotation Technique for Maximum Water Reuse)

'Advanced industrial wastewater treatment with ozone oxidation and flotation technique for maximum water reuse' (ADOXPOL) was a project aiming to develop a cost-effective, sustainable and advanced system for wastewater treatment that fulfils the need of the European industry to meet emission standards and apply water recycling.

For the purposes of the project, a prototype wastewater treatment system has been developed, which consisted of the following components:
- A novel ozone mixing and dispersion unit that generates microbubbles and performs even bubble dispersion for maximising contact between water and ozone.
-Innovative configuration of the unit to step reactor for ozone flotation.
- Pre-filtration unit with innovative mesh cloth with pore sizes of 60 microns and above.
- A computer-based process control system for monitoring key water quality parameters and control of ozone dosage and gas flow.

The prototype has undergone functional tests at an abattoir in the Czech Republic and at a fish oil and capsules manufacturing plant in Norway. Results attained showed that the technological objectives are achievable for effluents from food processing plants. The developed technology can be applied by the manufacturing industry. The ADOXPOL technology contributes to improvement of water quality in European recipients in line with the intentions of the Framework Water Directive. Pending intellectual property rights (IPR) protection hinders the consortium from releasing further information on the project.
