HOC8040-300
Reverse Osmosis Membrane For Sewage Treatment
Using a special membrane making process, it can reduce the adhesion and accumulation of organic matter, microorganisms and other pollutants on the membrane surface, and extend the cleaning cycle and service life of the membrane;
It has strong chemical stability and antioxidant properties;
It is suitable for various complex sewage water quality conditions, including high turbidity, high salinity, high COD, etc.

---Description
The flow rate of a single membrane element may be different, but the range of variation will not exceed +15%;
The stable desalination rate generally needs to be tested after 24-48 hours of continuous operation, depending on the inlet water quality and operating conditions.
