Abstract

We have investigated the impact of working pressure, the degree of sampling permeate, the pH of the medium on the transmembrane flow and retention capacity of a UPM-50 ultrafiltration membrane with respect to the dye acid yellow in the combination of the method of ultrafiltration and coagulation. It has been shown that the use of magnesium hydroxide for aggregation of anionic dyes makes it possible to substantially increase the efficiency of their membrane removal from the solution retaining high capacity of the ultrafiltration process.
