The reverse osmosis method, referred to as RO, is the most effective and modern water treatment method currently known. The so-called reverse osmosis principle refers to the application of appropriate pressure on the raw water end, so that pure water molecules pass through the reverse side from the high concentration side. The permeable membrane (TFC Membrane) reaches the low concentration side to produce pure water. At the same time, various impurities and harmful substances that cannot penetrate the membrane are discharged with the concentrated water. The reverse osmosis (RO) membrane is made of aromatic polyamide. The composite semi-permeable membrane. It is used to remove soluble salts, colloids, organic matter, microorganisms, bacteria, etc. in the water, and the quality of the produced water meets the water quality standards and sanitary requirements of purified drinking water. The reverse osmosis (RO) membrane of this system has the advantages of low energy consumption, low operating pressure, large water production, and stable water quality. The salt rejection rate of a single reverse osmosis (RO) membrane is ≈99%, and the salt rejection rate of the system is ≈97% (generally 98%).

Device control method:
1. The operation is simple, and the "fool type" one key can be used. After installation and debugging, there is no need to debug again, and complicated button switches and other operations are eliminated. The switch can be completed by only one key on the panel.
2. Fully automatic operation to realize unattended operation, automatic operation of system equipment, automatic protection, and automatic online monitoring. At the same time, the system can realize manual and automatic switching, and the equipment, water pumps, control valves, etc. can be manually operated under very operating conditions.
3. Self-protection function. A low-pressure pressure switch is installed at the inlet of the high-pressure pump. When the inlet pressure of the pump is lower than 0.05pa, the pressure controller will stop the equipment to ensure the safety of the high-pressure pump. A slow-open electric valve and a high-pressure pressure switch are installed at the outlet of each group of high-pressure pumps. When the outlet pressure is higher than 1.5Mpa, the pressure controller stops the equipment to ensure the safety of the high-pressure pump, membrane module and membrane housing.
4. Real-time monitoring of various operating parameters, at a glance, the reverse osmosis main inlet pipe is equipped with an online conductivity meter to detect the quality of the raw water; a fresh water flow meter and a concentrated water flow meter are set on the reverse osmosis device, according to the two flow rates Observe the operating status of reverse osmosis and adjust the recovery rate of the system; Set an online conductivity meter on the fresh water side of the reverse osmosis device to monitor the conductivity of the fresh water and calculate the system desalination rate; Pressure gauges are installed in the inlet, concentrated water, and sections of the reverse osmosis device , Monitor whether the reverse osmosis operation is normal; set a pressure gauge on the multi-media filter.
5. Liquid level control system, the relevant water tank is equipped with a liquid level controller, and the equipment is interlocked to control the start and stop.
6. When the reverse osmosis stops, the membrane surface is automatically flushed when it runs. RO equipment will automatically flush the reverse osmosis membrane when the system is shut down to avoid dirt deposits and fouling. It will automatically flush for 30 seconds every 2 hours to prevent membrane fouling and contamination. .
7. PLC control system, real-time online monitoring of equipment water quality is abnormal.
