The use of adsorption-active additions of some natural minerals for raising the quality of coagulation purification of natural water

Аннотация

laboratory, pilot and production tests were carried out aimed at the use of powder clinoptilolite jointly with aluminum sulfate to improve the quality of purification of the Dnieper river water. The article showed the advantages of a combined use of these reagents: higher degree of purification, lower consumption of regents, and smaller volume of deposits. The research has begun to obtain composite coagulant by treating with hot sulfuric acid of clinoptilolite and aluminum hydroxide. First research has been conducted of water coagulation under laboratory conditions using composite coagulant and its efficiency was demonstrated.
