4040 Industrial RO Membrane
This world-class ultra low-pressure 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.
