Single-stage reverse osmosis equipment is a backwash regeneration system for a single membrane element, which is suitable for occasions that do not require high water quality. The single-stage reverse osmosis device is mainly composed of pretreatment system, high-pressure pump, membrane module and instrument control. The principle of single-stage reverse osmosis equipment is to use a pressure gauge to control a certain pressure so that water passes through the water inlet. Under the interception of the membrane, the solute molecules in the water pass through the RO membrane and enter the concentrated water side; while the salt in the water (such as inorganic salts) ) and organic matter are trapped by the RO membrane and flow out at the concentrated water end.
When the concentrated brine needs to be desalinated, all the Na+ and Cl- in the raw water can be replaced with water greater than or equal to the pressure. Process reverse osmosis water treatment technology is an advanced separation and filtration technology. It uses a semi-permeable membrane (or selectively permeable membrane) to achieve the purpose of water purification through selective adsorption and screening of the semi-permeable membrane. It has the characteristics of high efficiency and energy saving, and can be widely used in electric power , Electronics, pharmaceutical and chemical industries to purify water and soften and remove alkali.
Since the resistivity of water produced by RO reverse osmosis can be as high as 18 megohm cm (25°C), it has become one of the production methods of electrodialysis and high-purity water. In addition, it can also be used in the early stage of industrial wastewater treatment and food processing water preparation.
