Abstract

Annotation.  Purpose. The The problem of inhibition sedimentation is studing in baromembrane installations. The solution of this problem is the use of antiscalant OSM 413. Technique. The experimental procedure is based on an increase in the total stiffness in the concentrate, depending on the effectiveness of the reverse osmosis membrane and the quality of the water. Results. The use of antiscalants based on polyacrylates is an effective way to prevent precipitation in baromembrane processes. The reagent OSM 413 is not only an inhibitor of formation of mineral sediment on reverse osmosis membranes, but it is also capable of removing old sediment, due to dispersing properties. Practical significance. Understanding the mechanism of action of the reagent based on copolymers of acrylic acid in industrial conditions and obtaining optimal reagent dosages which incoming water to the industrial installation.
