Ultrafiltration machine is a device that uses ultrafiltration technology to purify water. The difference from other water purification equipment is the use of ultrafiltration membranes. Ultrafiltration membrane is a microporous filtration membrane with consistent pore size specifications and a rated pore size range of 0.1-0.001 microns. The membrane filtration method using ultrafiltration membrane driven by pressure difference is ultrafiltration membrane filtration.
