Description:
BW aromatic polyamide composite membrane elements is specially developed to widely use forgroundwater and surface water treatment. The models are characterized in high rejection rate andhigh permeate flow.
It mainly applied to desalination treatment of brackish water, surface water, groundwater, tap water.etc. within salinity<5000mg/L, and can also used for waste water reuse , concentration and otherprojects. The application fields include electronics, electricity, municipal drinking water, chemicalspharmaceutical and so on. lt has the characteristics of high rejection rate, high permeate flux andlow operating pressure.
Applications:.
● Brackish water, groundwater, surface water, tap water treatment.
● Production water supply system for electronics, power, steel & iron, pharmacy, thermoelectric.petrochemical, Coal chemical industry etc
● Feed TDS above 5000mg/L.
