The Reverse Osmosis (RO) Membrane forms the heart of a Reverse Osmosis System. It consists of a semi-permeable membrane that allows water molecules to pass through but captures 99.8% of all other particles in the water. The RO Membrane removes bacteria, viruses, minerals, heavy metals, and pesticides from the water

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
