The Impact of Eutrophication on Water Quality and Related Measures - Transformations of Organic Matter Formed by Algae in Water Systems
(TRILATERAL I)

 

For many countries, especially in arid zones and/or in highly populated areas reservoir water is one of the most important fresh water resource for the supply of drinking water. The aim of this cooperation is to compare different environmental conditions leading to algal bloom within Middle European and Middle Eastern climates. Harvesting of algae and specific technology for the removal of organic substances originating from algae in reservoir water is an attractive means for a fast and economic solution. Therefore an approach aiming to optimize the classical methods of water treatment taking into consideration the prevention of algal bloom or the remediation of its damage to water quality will be developed. Treatment options that will be rested include filtration, adsorption, oxidation, and disinfection. The general approach will include studies on the effect of eutrophication, causes, effects, and potential treatment and pretreatment steps.

In each country the studies will be performed on model scale systems and in actual water supply systems. Comparison of water systems operated under different climatic conditions and the evaluation of different loads of nutrients of the systems and their effects will be studied. An intensive exchange of samples and a following joint interpretation of the data will result in advanced knowledge about eutrophication and its influence on water treatment. The findings will be discussed in relation to ecological aspects and from the viewpoint of water usage. Based on the projects results, measures for water quality control, water management and water treatment will be proposed. The central European experience which has been developed to date along with results collected in this project will be applied to the development of a system for treatment of reservoir waters in arid countries.
