Beketov national university of urban economy in Kharkiv popup.description2 The ways of improvement of the horizontal settling tank for systems of domestic and drinking water supply and ways to intensify biological wastewater treatment from organic pollutants were analyzed. The influence of the diameter of the tubular system for water distribution in the horizontal settling tank and the use of bioactive substances for the intensification of biological wastewater treatment is considered. The method of research of the improved horizontal settler is developed. The expediency of using a tubular system with different pipe diameters for water distribution in a horizontal settling tank has been experimentally confirmed. On the basis of analytical researches the technique of calculation of the basic geometrical parameters of a horizontal settler is proved. The proposed method of calculation will more accurately determine the size of the building and their number, which will reduce capital costs. An effective way to intensify biological wastewater treatment from various contaminants has been proposed. The use of carboxylic acids can have a comprehensive effect on cleaning processes: increase enzyme production, suppress the development of filamentous bacteria, increase resistance to toxic pollution. It is established that with the introduction of carboxylic acids the rate of oxidation of organic matter in aeration tanks increases, and the rate of decrease of ammonium nitrogen increases.
