Enhanced reverse osmosis membrane OV-OP
● Difficult industrial wastewater treatment
● Product performance and characteristics
Enhanced reverse osmosis membrane elements (OP) improve the chemical stability of the membrane with higher chemical cleaning resistance. The use of a 34 mil low-dropout feed channel spacer reduces fouling, decreases cleaning frequency, and extends the service life. These elements are suitable for the treatment of various challenging industrial wastewater streams.
