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.
