What is Effect of Flow Conditions on Ultrafiltration Efficiency of Dye Solutions and Textile Effluents about?

An ultrafiltration system with a tubular membrane module was used in an experimental study on the efficiency of organic dye removal from aqueous solutions and actual textile effluents. The module consisted of a polysulfone membrane which had been cast on the surface of a porous poly (methyl methacrylate) bar. It has been found that at an optimum velocity of feed flow (0.76 m/s), the retention coefficient for organic dyes of molecular weight greater than 780 exceeds 97%. A 200-h ultrafiltration of the textile effluent yielded removal efficiencies of 7545% and 50-60% for COD and TOC, respectively. Volume flux varied from 0.8 to 1.0 m"/m" d.
