PROBLEMS OF WATER INTAKE AND TREATMENT FOR WATER-SUPPLY FROM SOURCES WITH MUCH AQUATIC VEGETATION

Abstract

Influence of some types of algae on the water quality as well as factors causing the algae growth in reservoirs are examined. It is proved that the presence of algae in water supplied from water intakes for treatment causes the overload of treatment plants, increases filtration speed, reduces the effect of filtration, cuts the time of the filtration cycle, increases the amount of used reagents, etc. Basic methods for fighting against algae at water intake and treatment are shown.
