RO reverse osmosis desalting water purification equipment Reverse osmosis water treatment equipment as a special equipment for purifying water filtration production, using the selective transmission principle of reverse osmosis membrane, through the high pressure pump of the equipment to apply a certain pressure to the raw water through the reverse osmosis membrane, so that the water molecules in the raw water can be permeated through the membrane and out. However, other inorganic salts, microorganisms and organic matter can not penetrate the reverse osmosis membrane due to the interception characteristics of these substances, so as to obtain pure non-ionized water. ![]() Because the membrane aperture of reverse osmosis membrane is very small (only about 10A), it can effectively remove dissolved salts, colloid, microorganisms, organic matter, etc. (removal rate is as high as 97-98%). It has the advantages of good water quality, low energy consumption, no pollution, simple process and easy operation. It is the most energy saving and simple technology for desalination of seawater and brackish water and preparation of pure water. At present, it has been widely used in medicine, electronics, chemical, food, seawater desalination and many other industries. The RO system shall adopt automatic control operation mode according to the water level of the primary desalting tank and the system water production. If it is necessary to start, stop or switch the system, the operator shall confirm and manually switch the system. The control of RO system and the control of the entire chemical water treatment equipment are realized through the control system (PLC) in the control room. We select imported membrane components with large water permeability, high desalting rate, good chemical stability, good anti-pollution performance and good mechanical strength according to the raw water quality. We propose the maximum membrane flux, recovery rate and maximum water supply membrane area of membrane components according to the water quality and SDI value of the source water. The arrangement and combination of stages and segments of membrane modules are determined by influent water quality, recovery rate and water yield. RO is the most advanced and practical desalination equipment at home and abroad. This system uses reverse osmosis membrane of Dow Company. It can remove organic matter, bacteria and viruses, the membrane can be operated in ultra-low pressure working environment, so as to achieve energy saving, reduce equipment investment and operating costs. And to achieve the best combination of water permeability and desalinization, so Dow membrane has been widely used in the world, its technical performance and product quality has been praised by users. RO reverse osmosis purified water equipment maintenance troubleshooting 10 big problems! The switch is on, but the device does not start ① Electrical line failure, such as bad insurance, wire fall off ② The thermal protection element is not reset after protection (3) Water underpressure, check insurance, check everywhere wiring ② The thermal protection element is reset Check the waterway and ensure the water supply pressure After the device is started, the water inlet solenoid valve is not opened ① Cable shedding ② Solenoid valve internal mechanical failure ③ Solenoid valve coil is broken ① check the circuit ② Remove the solenoid valve for repair ③ Repair or replace the coil Pump running, but not up to rated pressure and flow ① pump reversal The filter element of the security filter is dirty ③ There is air in the pump (4) Rinse the solenoid valve to open, ① reconnect ② Clean or replace the filter element ③ remove the air in the pump ④ adjust the pressure after washing The pump is noisy when the system pressure rises ① The flow of raw water is not enough ② Raw water flow is unstable ③ Check the original water pump and pipes (4) Check the original water pump and pipeline, and check whether the pipeline leaks The solenoid valve is not closed after washing ① Solenoid valve control element and line fault ② Mechanical failure of solenoid valve ③ Check or replace components and circuits (4) Remove the solenoid valve and repair or replace it Undervoltage stop ① The supply of raw water is insufficient ② the filter element of the security filter is blocked (3) Improper pressure adjustment and automatic flushing cause underpressure ① Check whether the original water pump and pre-treatment system are working ② clean and replace the filter element ③ Adjust the system pressure to the best state, so that the pressure after filtration is maintained at more than 20psi The concentration water pressure is not up to rating ① pipeline leakage The flushing solenoid valve is not completely closed ③ The recovery system leaks ① Check and repair pipelines ② Check and replace the flushing solenoid valve ③ Check and repair the recovery system The pressure is adequate, but the pressure display is not adequate ① The pressure gauge hose is blocked with foreign matter ② There is air in the hose ③ Pressure gauge fault ① Check and dredge the pipeline ② Remove air ③ Replace the pressure gauge Deterioration of water quality ① Membrane pollution and scaling (2) film junction seal aging failure ① Chemical cleaning is carried out according to technical requirements ② Replace the O-ring ③ Replace the film Production decline (1) Membrane pollution and scaling should be cleaned chemically according to technical requirements ② Water temperature change is determined by recalculating the actual water temperature |
