FFM Inc's ultra-low pressure reverse osmosis membrane is the lowest operating pressure in the existing reverse osmosis products. The conventional operating pressure range is 0.5-1.2mpa. It is also one of the reverse osmosis membrane elements with the lowest operating pressure in the world. FFM Inc's ultra-low pressure reverse osmosis membrane is mainly used for municipal tap water, groundwater and surface water with salt concentration less than 1000ppm, which is widely used in the preparation of purified water. FFM Inc's ultra-low pressure series reverse osmosis membrane has lower operating pressure and energy consumption, so the economic benefit is improved to a greater extent.
