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

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.[...].
