Influence of Water Acidation Degree on Quality of Permeate of a Reverse Osmosis Plant

Summary

The results of industrial tests of the plant of reverse osmosis water desalination installed in the chemical water treatment shop of the Samara hydropower station are presented. Influent water is subjected to pre-treatment in clarifiers with liming, filtering on mechanical filters and two-stage Na-cation exchange. The influence of acid doses in the course of influent water acidification and the value of permeate output on its quality is studied. The evaluation of convergence of calculated data performed with the help of specialized software with the actually received values of permeate quality is made. Оbserved dependences allow us to make adjustments of the permeate quality obtained by the calculation method.
