It delivers permeate flow up to 11.2 m³\/day and provides up to 99.3% salt rejection. The membrane is recommended for feed water with TDS up to 2500 mg\/L* and can also be applied in systems with elevated nitrate and silicate levels in the feed water.\u003c\/p\u003e\n\u003cp\u003eEcosoft HR membranes are manufactured using technology that supports long-term and reliable system operation.
