4040 BW Superflow Membrane

4040 Industrial RO Membrane

nThis world-class 4040 industrial ro membrane delivers high permeate flows and salt rejection at lower raw water pressures, compared to regular low-pressure membrane elements.  Suitable for brackish and bore water, however, a higher silt density index may require additional treatment.  It operates under approximately 2 thirds of the operating pressure of a regular low-pressure composite membrane and achieves a salt rejection rate of up to 98.0%.  The lower energy requirement decreases the equipment cost in particular pump rating and pressure rating of the membrane housing.n
