BW-湖州浩宇膜科技有限公司

Howie BW series RO membrane offers the advantages of high fouling resistance and high flux. The membrane is made by special manufacturing process that improving the hydrophilicity and charge characteristics, thus reduces the proliferation and adsorption of contaminants and microorganisms on the membrane surface during operation. Effectively reducing membrane fouling, lowering transmembrane pressure, stabilizing production operation, decreasing cleaning frequency, and extending the service life of the membrane element.
