The process of ultrafiltration treatment of aqueous solutions to remove humic acids has been studied under conditions of adding complexation polymers (polydiallyl dimethylammonium chloride, polyacrylamide, polyvinylpyrrolidone, and chitosan). It was shown that the highest values of the retention coefficient for humic acids were observed in case of using polydiallyl dimethylammonium chloride (R = 98.1%) and chitosan (R = 90.5%). The impact of the solution pH on the degree of removing humic acids was also investigated.
