It's known that caustic / alkali / soda/ lye are expensive and widely applied in industry production and the subsequent caustic wastewater/ soda wastewater is not only dangerous to our environment, but also contains precious lye / alkali / soda.  This tubular membrane tipical application is to deal with strong caustic / soda wastewater for its superior tolerance to strong acid and soda. Kaimi tubular ultra-filtration tubular membrane is made of modified PES and lined in its supporting steel tube. The most distinctive advantage is its tolerance to 15% H2SO4, 20% NaOH and pH 0-14. Anti-polluting and anti-scaling also result in its competitiveness with 12.5mm wide channel. so it
s widely applied in wastewater of high solids, high viscosity and its MWCO reaches 30000 Dalton, absolutely can meet ultra-filtration requirements.


-Unique and optimized tolerance to strong acid and alkaline wastewater.
-Lined Supporting tube in membrane module is detachable, convenient for cleaning and   replacement.
-Wide channel, anti-scaling and anti-polluting.
-Good flux recovery
-Narrow pore size distribution, high filtration precision
-Strong mechanical strength
