Product Description
The SW series reverse osmosis composite membrane is made of interfacial polymerization of nanoparticle mixed matrix materials developed by a new generation, combined with high-precision, fully automatic component rolling technology, to achieve the application effects of high desalination and high pressure resistance of products.
This technology helps us obtain resources such as fresh water and chemical minerals from inexhaustible seawater, and realize efficient recycling of resources from high-salt industrial wastewater that has a significant impact on the ecological environment.
The product is suitable for:
TDS > 10,000mg/L seawater desalination
Brine treatment
High-salt industrial sewage processing
Reclaimed water treatment
RO/NF treated concentrated water
Other high-salinity water sources
