SINOMEMB®Brackish water SNBW-FR Series Fouling Resistant RO membrane elements
SINOMEMB® series fouling resistant (SNBW-FR) membrane elements are made of fouling resistant membrane and widened feed conduit (34mil-56mil, customized according to customer's working conditions). The membrane surface is more smooth and hydrophilic, and the membrane charge is closer to electric neutral, which can destroy the foundation of fouling and organic pollution blockage.The membrane element has stronger ability to resist inorganic salt scaling and colloid and organic pollution, which greatly improves the cleaning and recovery performance of the membrane, broadens the application field of the membrane element and to the greatest extent prolongs the service life of the membrane element.The system can still maintain a low pressure drop,high durability, high removal rate and high water yield even under high pollution conditions,make this series of Brackish water RO membrane elements superior throughout its life cycle.
3.1Brief introduction
SINOMEMB® series fouling resistant membrane elements (SNBW-FR) are suitable for water supply with salt content below 10,000 PPM and strict pretreatment but still containing organic pollutants in the water.Due to the smooth surface of the membrane, good hydrophilicity, close to electric neutrality, and widened water supply conduit, greatly reduce the adsorption and accumulation of bacteria and microorganisms on the membrane surface, so that it not only has strong the feature fouling resistant, but also has effective recovery after chemical cleaning.It is widely used in urban sewage and industrial waste water regeneration, desalting of slightly polluted surface water and recycling of cooling circulating waste water.
