Abstract

Annotation. Purpose study antiscalant polyacrylic acid. Getting the dosage depending on the reagent used, the hardness of the incoming water. Methods. The experimental procedure is based on the increase in the overall stiffness of the concentrate, depending on the effectiveness of the reverse osmosis membrane, and the quality of the source water. Results. Application antiscalant based on polyacrylic acid is an effective way to prevent sedimentation in baromembrane processes. Antiscalant dosage based on polyacrylic acid is almost 10 times less than antiscalant based phosphonic acids. Practical significance. This equation approximation has wide practical application.
