What should I pay attention to when using small and medium-sized industrial RO pure water treatment equipment? Author of the article: In a serious water pollution today, small and medium industry RO water treatment equipment brought water for the health and safety more and more people. When using small and medium-sized industrial RO pure water treatment equipment, the most important point is to ensure the normal operation of the equipment. The normal operation of the equipment can be guaranteed to use water, and the stable operation of the equipment must be inseparable from the usual maintenance and correct use. Let me introduce to you what you should pay attention to when using RO pure water treatment equipment for small and medium-sized industries. 1. Strictly control the inlet water quality to ensure that the device is carried out under the water quality conditions that meet the requirements of the inlet water index. The inlet water quality does not meet the requirements, which is very easy to cause the fouling of the reverse osmosis membrane, causing the consumables to quickly fail and seriously affecting the outlet water quality. 2. The total water inflow of reverse osmosis is controlled by the RO water inlet control valve. If the reverse osmosis water inflow does not change, do not disturb the RO water inlet control valve, and it is strictly forbidden to open or close it fully. The RO concentration control valve is used to adjust the recovery rate of the system. If the recovery rate does not change, do not disturb the concentration control valve. It is absolutely forbidden to fully open or close. 3. The device should not be shut down for a long time, and run for less than 2 hours a day. If it is going to be shut down for more than 72 hours, use a chemical cleaning device to fill the components with 1% sodium hydrogen sulfate and 18% glycerin for protection. 4. The reverse osmosis device should be flushed for 10 minutes under the condition that the inlet water pressure is lower than 0.4Mpa every time it is started after shutdown. 5. The operator should record the operating parameters every hour to check the use of pure water equipment and the quality of the effluent. The main record content should include: Influent: PH value, conductivity, pressure, SDI, water temperature. Product water: conductivity, flow, PH value; concentrated water: flow, pressure and inlet pressure of each section. 6. High and low pressure alarm of reverse osmosis device: When a high and low pressure alarm occurs in the reverse osmosis device, first check whether the opening of the manual valve between the security filter and the high pressure pump is too small, and then check whether the RO water inlet regulating valve and the thick discharge valve are too small If it is normal, press the high and low voltage alarm reset button again to restart the equipment. 7. The operating pressure control should be as low as possible on the premise of meeting the water production and water quality. This will help reduce the attenuation of the membrane water flux and reduce the membrane replacement rate. 8. Inlet water temperature control should be based on the actual water consumption, and the critical pressure (the pressure value at which the inlet water pressure is lower than this value and the desalination rate will significantly decrease) can not meet the low temperature of the product water and water quality requirements as the inlet during this time period. Water temperature, which can reduce the attenuation of membrane water volume. This is the end of the introduction about what to pay attention to when using small and medium-sized industrial RO pure water treatment equipment. When using it, pay more attention to the above points to make the equipment run better. There is a wide range of environmental protection water treatment equipment, and a professional after-sales team will provide solutions to various problems of your equipment.
