FFM Inc\'s membrane rich ultra-low pressure series reverse osmosis membrane has the advantages and characteristics of high desalination rate and low operating pressure. The conventional operating pressure range is 0.8 ~ 1.2MPa. Ultra low pressure series reverse osmosis membrane is mainly used for municipal tap water, groundwater and surface water with low to medium salt content. Its operating pressure is about 2 / 3 of that of conventional low pressure composite membrane, and the desalination rate can reach 99.5%. LP ultra-low voltage series greatly reduces the equipment manufacturing cost and equipment operation cost, so the economic benefit is obvious. Ultra low pressure series reverse osmosis membranes are widely used in water purification plants, food, beverage, dairy products, drinking water, electronics, medicine and other light industries.
