Treatment of surface waters with polymeric ultrafiltration membranes

Among all the technologies of water treatment, membrane technology appears to be the most promising. The major advantage of this technology is its ability to produce the water of a constant and well adjusted quality. Moreover, membranes remove a broad spectrum of substances, ranging from particles to ions, including bacteria and viruses, and they can operate without any addition of chemicals to raw water. The paper discusses the results of investigations concerning the application of polymeric ultrafiltration membranes in the treatment of surface waters. The effectiveness of the process was assessed by measurements of the volumetric permeate flux as well as by microbiological and physicochemical analyses.
