Reduction and Softening of Technical Water Hardness Based on Research Results

Abstract

The article presents the results of a study to determine the colloidal properties of mechanical impurities in the Tudakul and Kuymazar waters. The dispersion of solid particles of mechanical impurities was determined by sieve analysis (sizes from 0.25 mm to 50 mm). The chemical reactions occurring using various reagents to reduce the hardness of the test water were also studied. The decrease in the amount of fine solid particles of mechanical impurities during their coagulation from 24.3% to 15.3% in a gravitational field is investigated.
