Shandong industrial reverse osmosis equipment

Jinan Shengyuan Water Treatment Equipment Co., Ltd. specializes in the production of reverse osmosis equipment. The entire reverse osmosis system consists of raw water booster pump, multi-media filter, antiscalant addition, security filter, high-pressure pump, reverse osmosis membrane, pressure vessel, and corresponding It is composed of instruments, meters, valves, racks, pipes and fittings. The reverse osmosis membrane is a new type of polymer separation membrane driven by pressure. Driven by pressure, water molecules in the solution pass through the membrane, while other macromolecules, anions and cations, bacteria, viruses, etc. are intercepted, thereby achieving the purpose of purified water. Purpose. The pore size of the reverse osmosis membrane is smaller than 100, which can effectively remove divalent ions. The removal rate of monovalent ions can reach up to 100%, and the removal rate of low molecular weight organic matter can reach up to 100%. It can effectively remove pathogenic microorganisms, various bacteria and viruses. The effluent burst-causing activity test was negative. The reverse osmosis system can remove above-mentioned minerals, bacteria, viruses, pyrogens and bacterial endotoxins from raw water. Compared with anion and cation exchange beds, reverse osmosis devices have the advantages of simple equipment operation, no acid and alkali regeneration pollution, and low operating costs. Therefore, reverse osmosis devices are now gradually replacing anion and cation exchange beds.

Reverse osmosis membrane cleaning services
Although the reverse osmosis device adopts a reasonable pretreatment system and good operation management, it can only To minimize the pollution of the reverse osmosis membrane, it is impossible to completely eliminate the pollution of the membrane. Therefore, after a period of normal operation of the reverse osmosis device, it will be contaminated by various trace organic and inorganic substances. When the membrane is contaminated, obvious symptoms such as increased water production, desalination rate and pressure drop at the inlet and outlet of the reverse osmosis device will often appear. When the water production of the device decreases (at the same temperature and pressure), the salt permeability doubles, and the pressure drop doubles, and when one of these three phenomena occurs, chemical cleaning is necessary. At the same time, when the reverse osmosis device needs to be out of service for a long time, chemical cleaning is also required before protection. It is worth noting that if the inlet water temperature decreases, it will also lead to a decrease in water production. This is normal and does not mean that the membrane is contaminated. Failures in pretreatment, high pressure, etc. will also cause inlet water pressure, inlet water flow, and water production. Decrease in flow rate and desalination rate. When chemically cleaning, the first thing to do is to determine the type of contaminants, and then select the appropriate cleaning formula and cleaning process based on the characteristics of the membrane. Pay attention to controlling the value, temperature and inflow of each component of the cleaning fluid. The cleaning effect can be confirmed by comparing the desalination rate, water production and pressure drop of the device before and after cleaning. In addition to periodic chemical cleaning, each After shutdown, it is effective to use pretreated water or reverse osmosis water to reduce the speed of membrane fouling, extend the chemical cleaning cycle and extend the service life of the membrane.
