SINOMEMB®Brackish water SNBW-XFR Series ultra fouling resistant RO membrane elements
SINOMEMB(SNBW-XFR) series of ultra fouling resistant membrane
elements are the latest development to improve system resistance to
organic biological pollution and help solve difficult water
treatment problems.Compared with traditional fouling resistant
membrane elements, the membrane desalting layer is more uniform and
smoother.Elements selected 34 mil wide flow channel and more
membrane distribution design, and using the latest design of the
eddy current water distributor without dead Angle to achieve ULDO,
the system can achieve better water distribution, water can be more
evenly distributed to the membrane element of the system, so that
the membrane element of microorganism and organic compound fouling
resistance ability is stronger, and greatly improve the performance
of membrane cleaning to restore.It broaden the application field of
membrane elements and prolongs the service life of membrane
elements. The advantages of high durability, high organic matter
removal rate, high water yield and low energy consumption even
under high pollution conditions,make the elements more outstanding
in the whole life cycle.
4.1 Brief introduction
SINOMEMB®(SNBW-XFR) series fouling resistant membrane elements are
suitable for water supply with salt content below 10,000 PPM and
strict pretreatment, but the feed water still contains organic
microorganisms and other pollutants.Due to the membrane surface is
smooth, good hydrophilicity and close to neutral, widening of the
feed water flow and vortex no dead Angle design of water
distribution,it greatly reduces the bacteria, microorganisms in the
membrane surface adsorption and accumulation, to make it not only
has the strong feature of fouling resistant, but also have a more
effective recovery after chemical cleaning. The series of membrane
element washing time is reduced compared with other series,the
reduction can be as high as 40%, which is widely used in various
difficult water treatment applications such as recycling of urban
sewage and industrial wastewater and near-zero discharge treatment.
