Obiettivo
Scientific objectives and approach:
A large number of existing waste water treatment plants were designed long before their construction started and have not always been adapted to take into account increases in population and pollution or technological changes. As a consequence, these water treatment plants were, in most cases, of insufficient size or technical capacity to cover the needs of the agglomerations served. Such cases have been identified by the European Court of Justice in a number of Member States. Overall, as an EU study has shown, the cost of implementing the UWW Directive in nine Member States could reach ± 201.120 million EURO s (May 1995). For France it is estimated to reach ± 12.355 million EURO for the sewage plants only, without considering the collection systems. For Greece it is estimated to reach 1.000 million EURO, for Portugal 1.300 million EURO, for Spain (only for Objective 1 regions) 5.500 million EURO and for Ireland 550 million EURO.
The increase in the number of sewage plants has a significant impact on the generation of sludge. According to a Commission survey in 1994, 6.5 million tons of sludge are produced each year in the EU. Around 40% of the sludge produced in the EU comes from 1.3% of the sewage plants, from urban centres with more than 100.000 p.e. It is therefore necessary for sewage plants in large urban centres to be improved technically so that they can produce treated sludge as organic fertiliser, which is compatible with the terms defined by the UWWT Directive. The European Commission expects an increase of 50-60% in the sludge generated over the next 10 years. Additionally there are industrial processes as well which have the need of improvement regarding the activation of biological systems. These systems would have different purposes:
- "Airlift" systems which are used for the production of useful biological sludge require optimisation.
- Increase of oxygen contents of waste water in waste water drain systems, to improve the efficiency of wastewater treatment plants.
- Application of industrial waste water treatment plants used for a pre cleaning.
Problems to be solved:
The aim of the Urban Waste Water Treatment Directive (UWWT Directive 91/271/EEC) is that by the year 2005 almost all agglomerations in the EU above 2.000 population equivalent (p.e.) should be provided with collecting systems and waste water treatment plants. Taking into account the fact that many small municipalities do not yet have sewage plants, it can be estimated that around 40.000 plants will need to be built or renewed by the end of 2005 in order to meet the new European water pollution limit values. The European Court of Justice has estimated that almost 30% of the plants built before 1992 ought to be upgraded. In the case of Belgium and Italy, existing plants are like wise in need of upgrading. In the case of Member States which have not yet defined more sensitive areas (where plants must be of the tertiary treatment type) the figures for such plants will probably be higher. Provision of technology to upgrade existing small, medium and large scale wastewater treatment plants for increased throughput and nutrient removal with special focus on elimination of nitrogen and phosphorus, and requiring only a minimum capacity investment.
Provision of efficient and cost-effective small-scale treatment plants (<5.000 p.e.) which conform with recent and future regulations and obtain noticeably better degradation efficiency especially for nitrogen and phosphorus compounds.
Significant reduction of the sludge generation.
Provision of efficient systems to increase oxygen contents in biological reactors
Expected Impacts:
The proposed project will make a clear contribution to solve these four problems. The objective of this project is the development of a new aeration system based on adsorptive oxygen enrichment in combination with bio-membrane technology for competitive small-scale waste water treatment systems and the retrofitting of existing waste water treatment plants for significantly improving their treatment efficiency and reducing their sludge generation. The development of the ITEWAT system has the potential to provide substantial savings in capital costs and life cycle costs for nutrient removal for new and existing waste water treatment plants. Referring to the Programme "Energy, Environment and Sustainable Development", the project will contribute to the EU's objective of developing technologies to improve waste water treatment through process optimisation and to minimise environmental impacts from waste water treatment with a focus on compact, environmentally friendly and cost-effective treatment technologies and a reduction of bio-solids and sludge.
