Project description:

Background

Scope exists to improve the effectiveness of conventional mechanical and biological wastewater treatment technologies in the Czech Republic. Risks currently arise from hazardous residues from pesticide compounds and medicinal substances, which can become an environmental pollutant and pose problems for human welfare. The threats can be reduced by using modern tertiary treatment systems. Such developments will help Czech municipal water authorities to meet EU standards for controlled substances, such as bisfenol, 17 alpha-ethinylestradiol (EE2), 17 beta-estradiol (E2) and diclofenac.


Objectives

The objectives of the LIFE2Water project was to implement innovative technologies to improve the treatment of municipal waste water while also testing and verifying those technologies at pilot scale with the aim to improve the status of aquatic ecosystems. To achieve this; three pilot plans were built: one to test micro-strainer filter/UV radiation, one to test ultrafiltration, and the last one to test sonolysis of ozone. The pilot plants were connected to municipal waste water treatment plants for long-term testing, verification and optimisation. The project monitored how efficient the technologies were in removing selected pollution and evaluated them from an economic, environmental and operational perspective. The monitoring included selected industrial substances (bisphenol A, nonylphenol and octylphenol and their metabolites), pesticides (atrazine and its metabolites, MCPA, MCPP, MCPB), pharmaceuticals (17α-ethinylestradiol, 17β-estradiol and its metabolites, diclofenac, carbamazepine, naproxen), and microbial contamination (faecal coliforms, enterococci and Escherichia coli). Another objective of the project was to raise awareness of these issues through dissemination activities.


Results

The LIFE2Water project successfully reached its objectives. Three pilot plants were constructed and tested in one-year: Micro-strainer filter/UV radiation, Ultrafiltration, and Sonolysis of ozone , to find an innovative solution to the problem of the treatment of municipal waste waters and the end results brought valuable information. LIFE2Water tested and compared the technologies from the point of view of their efficiency in terms of removing pollutants and also looked into the operational aspects (e.g. the overall costs, maintenance demands, chemicals and energy consumption). The project made the results available to anyone planning or operating water treatment plants. The results of this experience have already been used by all three project partners.

The three pilot plants allowed to treat the tested water and remove the following contaminants: 101 grammes of pharmaceuticals, 10 grammes of pesticides and their metabolites, 4 grammes of alkylphenoles, 8 kg of BSK5, 301 kg of CHSKCr, 424 kg of suspended solids and 9 kg of phosphor.

The partners found that project results have the potential to not only influence the methodological and technological approaches to treating municipal waste waters but also the legal framework (in terms of monitored parameters, limits for treated waste waters and even the policies on the use of recycled waters). The results and recommendations will not only contribute to expert discussions they can now also be used as a basis to take decisions on the appropriate water treatment technologies and for the design of future treatment plants.

It is very likely that the results of the projects will have some policy implications in the near future in terms of incorporating the pollutants of concern in the relevant legislation on treated waters and in updating the legislation in the field of the use of recycled water.

After testing the technologies the project went on to disseminate the results and recommendations to water managers and relevant state institutions. Since the testing also led to reductions in energy consumption and in the use of chemicals, this gave rise to a number of recommendations from the partners on how to improve the efficiency of waste water treatment in the future. The project also developed new procedures for sampling and improving the analytical methods used to test the level of contaminants (including lowering the detection limits). The information campaign was very successful and was met with much interest from experts, journalists and the general public. The project has thus successfully managed to increase the awareness of the impacts of pollution on human health and ecosystems.

The transferability of the results was one of the main aims of this demonstration project. The coordinating beneficiary AQP plans to use the experience from the project for enhancing its technical assistance for water treatment companies.

In conclusion, the results should contribute to reducing the cost of municipal waste water treatment operations and increase the efficiency of the methods used. The project is also expected to act as a catalyst for reviving the market (technology producers, engineering companies, laboratories, and consultants).
