High Salt Rejection Seawater Desalination Membrane 8040 RO Membrane Wastewater Treatment
High Salt Rejection Sea Water Desalination 8040 Membrane For High-salinity Wastewater Treatment
Description:
Aromatic polyamide composite SW series membrane elements is newly developed for seawater desalination or treatment for raw water with high salinity, with stand high pressure.It is mainly used for seawater or raw water with high salinity > 10000mg/L; Its appication fields include seawater desalination, RO concentrated water reuse, zero liquid discharge for high salinity wastewater, materials concentration and so on. It has the characteristics of high desalination rate,stable performance and high flux.
Applications:
● Seawater desalination.
● Industrial applications for landfill leachate sewage wastewater treatment, high-salinity wastewater concentration etc.
● Minimal or zero liquid discharge.
● Feed TDS above 10000mg/L.
