SWC5MAX Equivalent to BWSW-8040-440-HF

SW series fouling-resistant and scaling-resistant aromatic polyamide composite membrane elements developed by Besta Membrane are designed for complex water quality. The SW series membrane elements use a special membrane preparation process, which gives them an extremely high sodium chloride desalination rate and boron rejection rate. This allows for a reduction in the cost of achieving the water quality required by WHO standards. Additionally, the products have a high degree of chemical cross-linking, enabling them to withstand more frequent chemical cleaning cycles and adapt to high pressure and high salinity environments.

SW series membrane elements are suitable for desalination of high-concentration seawater and brackish water desalination with high recovery systems. They are widely used in seawater desalination projects and can also be applied in reclaimed water reuse and zero discharge projects.
