Compared to traditional filtration technologies that rely on a screen or filter to remove particles, reverse osmosis (RO) is a pressure-driven separation process that employs a semipermeable membrane and the principles of crossflow filtration.
Nanofiltration (NF) is a membrane liquid-separation technology sharing many characteristics with reverse osmosis (RO). Unlike RO, which has high rejection of virtually all dissolved solutes, NF provides high rejection of multivalent ions, such as calcium, and low rejection of monovalent ions, such as chloride.
Ultrafiltration (UF) is a pressure-driven purification process that separates particulate matter from soluble compounds using an ultrafine membrane media. Ultrafiltration is an excellent separation technology for desalination pretreatment, reverse osmosis pretreatment, and wastewater reclamation, as well as for producing potable water.
Submerged UF filtration system adopts an open external pressure ultrafiltration membrane module, which is completely submerged in the membrane pool, siphoning and pumping the produced water under negative pressure through the suction pump. The membrane module replaces the traditional coagulation, media, filtration and other technological processes, and is widely used in the fields of drinking water safety, sewage treatment plant marking, river
Membrane Bioreactor is a new wastewater treatment process that combines membrane separation technology and biological treatment technology. It is composed of biochemical reaction system and membrane components. It uses membrane modules to trap activated sludge and macromolecular organic substances in the aerobic biological reaction tank, so as to increase the concentration of activated sludge. Hydraulic retention time (HRT) and sludge retention
