4021 Low Pressure Reverse Osmosis RO Membrane for RO Water System
Commercial reverse osmosis membrane elements are widely used in
electric power, petrochemical, steel, pharmaceutical, food and
beverage, municipal and environmental protection fields. It plays
an important role in seawater desalination and brackish water
desalination, boiler water supply, industrial pure water and
electronic ultrapure water equipment, drinking pure water,
wastewater treatment and special separation processes.

- Under certain conditions, the presence of free chlorine and other
oxidants in the water may cause serious membrane damage, which
doesn't belong to product warranty range.
RO membrane continues to increase in demand with the growth of the
water treatment sector. However, fouling and scaling are its major
drawbacks. Fouling occurs in both cellulose-based and thin-film
composite membranes. So we have professional R&D and after sale
service for our customers.
