Anotace: The article presents the results of the research, obtained during the production of a new reagent - sodium permanganate oxidant (Carusol trademark) in the technology of water treatment at the treatment plant of the «Zhytomyrvodokanal» utility company. The purpose of this work is to determine the effectiveness of removal from the composition of tap water of such pollutants as permanganate oxidation, manganese, phytoplankton, and especially chloroform and improve its quality by organoleptic parameters.

This experiment was conducted in summer to determine the technological and environmental efficiency of the reagent at high water temperatures, because it is in summer that the water supply source in Zhytomyr is characterized by the increased levels of organic pollution, which causes excessive concentration of chloroform, high concentration of manganese and phytoplankton. The production experiment showed that the efficiency of water purification with Carusol reagent in the warm period of the year at increased water temperatures in terms of chromaticity is quite high; according to the oxidation index of permanganate, although it is not sufficient for the normative quality of drinking water and requires the use of additional activated carbon for more thorough removal of organic pollution; there is a high technological and environmental efficiency of purification of drinking water from chloroform, in some experimental days the efficiency was up to 60-70%; oxidation of manganese occurred by 60-90%; removal of phytoplankton with the reagent was characterized by high efficiency and was at the level of 90% or more.
