The overall aim of the project is to revitalise water affected by eutrophication in the Danube Region. The high content of nutrients and undesirable elements in the water (mainly nitrogen and phosphorus) causes excessive growth of microorganisms, mainly algae and cyanobacteria that causes the loss of oxygen in the water and limiting of higher forms of aquatic life, especially fishes in the throughout the food chain.The project will therefore serve to verify laboratory proven technology in the external conditions for the backwater lakes, dams and meanders for different polluted water and water bodies of different sizes.These issues were consulted with several institutions of the Danube region as Germany, Austria, Hungary and Serbia, where there were substantial high interests in this unconventional solution.Project methodology is based on scientific research of the project participants.The specific START objective is to extend and modify patented technology through cooperation, through verification of the effectiveness of the new technology with the aim to disseminate results into practice. Expected Results: 1. common procedure for solving common environmental problems2. improving the water quality3. improved parameters to tackle water pollution
