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

In arid zones and/or in highly populated areas, reservoir water is one of the most important fresh water resources for the supply of drinking water. Its quality may be deteriorated by eutrophication processes.

To investigate the impact of eutrophication on the quality of selected water bodies, a trilateral co-operation was started in the year 2003. The aims of this co-operation are to study the causes of eutrophication under Middle European and Middle Eastern climates, to investigate its effects on water quality, and to select and apply encountering treatment steps.

During the first two years, basic hydrological, waterchemical, -physical, and biological data of the selected water bodies were collected and compared. Algal blooms occurred regularly in the Middle Eastern water bodies, but were not observed in the German waters under investigation. The focus of the future investigations of the Israeli and Jordanian groups will therefore be “on the preventive side”, i. e. monitoring and reduction of nutrients and study of the effects of atmospheric parameters on eutrophication (Jordan) and investigation of growth conditions for selected algae, with a focus on micronutrients (Israel). The Israeli and Jordan groups will also investigate the suitability of algal biomass for its sustainable use as a nutrient resource in agriculture. The German group will focus on the application of membrane filtration and combined techniques for the removal of cyanobacterial and algal cells and metabolites. On the basis of the results, measures for water quality control, water management and water treatment will be suggested.
