Investigation into the influence of natural powdered zeolite on drinking water treatment at Druskininkai waterworks III

Abstract

Until recently, at Druskininkai Waterworks III aerated groundwater has been treated in open iron removal filters with crushed granite filter media. The equipment to do this was built in 1983. The existing groundwater treatment equipment cannot ensure a very good quality of drinking water. Measuring of the concentration of organic matter (permanganate index), iron and other substances in water began since 2000 after the new Hygiene Norm HN24: 1998 was accepted in 1998.[...].
