Description
ULP11-4040 RO Membrane Element 2400 GPD |Vontron
Vontron Low Pressure Reverse Osmosis Membrane, 2,800 gpd ULP11-4040
Vontron ULP11-4040 RO membrane is a ultra-low pressure polyamide compound membrane element.
This world class ultra low pressure 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 higher silt density index may require additional treatment. It operates under approximately 2 thirds of the operating pressure of 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.
