What problems should be paid attention to when installing and using two-stage reverse osmosis EDI pure water treatment equipment? Author: EDI two-stage reverse osmosis water treatment equipment because of its good water purification effect, has become the most used industrial process water treatment equipment. Some users will inevitably have some small problems during the use of the two-stage reverse osmosis EDI pure water treatment equipment. Although the seemingly minor problems may easily lead to the obstruction of the equipment operation. Here, the environmental protection editor tells you some precautions for the use of two-stage reverse osmosis EDI pure water treatment equipment, so that mistakes during use can be avoided. 1. The total water inflow of the two-stage reverse osmosis EDI pure water treatment equipment (that is, the sum of the product water and the concentrated water) is controlled by the RO water inlet regulating valve. If the two-stage reverse osmosis EDI pure water treatment equipment has no change in the water intake, then Do not tamper with the RO inlet control valve. Fully open or fully closed is strictly prohibited; the RO thick discharge control valve is used to adjust the recovery rate of the system. If the recovery rate does not change, do not tamper with the thick discharge control valve. Fully open or fully closed is absolutely prohibited . 2. When a high and low pressure alarm occurs in the two-stage reverse osmosis EDI pure water treatment equipment, first check whether the opening of the manual valve from the security filter to the high pressure pump is too small, and then check whether the RO water inlet regulating valve and the thick drain valve are normal, and then Press the high and low voltage alarm reset button to restart the equipment. 3. Operating pressure control should be as low as possible under the premise of meeting the water production and water quality, which will help reduce the attenuation of the membrane water flux and reduce the membrane replacement rate. 4. 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 minimum temperature of the water production and water quality requirements as the minimum temperature within the time period. The inlet water temperature can reduce the attenuation of the membrane water volume. 5. Discharge volume control. Due to changes in water temperature, operating pressure and other factors, the water production volume of the device will also change accordingly. At this time, the discharge volume should be adjusted, otherwise it will affect the desalination rate of the device. Precautions for the installation of two-stage reverse osmosis EDI pure water treatment equipment:    1. The installation site of two-stage reverse osmosis EDI pure water treatment equipment should be level and clean, close to power and water sources. Keep away from fire sources and any heating elements.  2. Ultra-pure water equipment must not be installed outdoors in northern areas to prevent freezing inside the equipment and damaging the instrument and filter elements.  3. The installation location of the equipment should be convenient for drainage, so that the drainage pipe of the equipment can be kept smooth.  4. When the water source pressure is less than 0.12Mpa and the flow is less than 3.0T/H, the phenomenon of multi-stage pump starting---stop---start will occur repeatedly during the operation of the machine. At this time, the machine should be stopped to prevent burning of the motor, and areas with insufficient water pressure and flow. Please add a raw water tank in front of the equipment.  5. Ensure that the working pressure of the pump used in the ultrapure water system is 1.0-1.2Mpa to ensure that the pump works within its rated head range. The above points are the precautions for the use of two-stage reverse osmosis EDI pure water treatment equipment. Mastering this knowledge can reduce equipment failures and ensure the quality of product water. In addition to the precautions for use, the maintenance and maintenance of the equipment is also very important. Would you like to know how to maintain and maintain the reverse osmosis equipment?
