Ultrafiltration of solutions of Bromocresol Purple on a UFM-50M membrane in the presence of dispersed carbon was studied. The variation of the flow rate through unit surface area of the membrane and of the dye retention factor with time was traced. The influence exerted on the ultrafiltration by dye adsorption on dispersed carbon and by formation of a dynamic membrane was determined. For the initial stage of filtration, the dependence of the retention factor on the dye concentration in solution was found and accounted for.
