Installation process small industrial reverse osmosis water purification equipment and precautions for use of the article: small industrial reverse osmosis water purification equipment is used in industrial production up to a water treatment device, the user brings a lot of convenience and benefits. The reverse osmosis membrane used in small industrial reverse osmosis water purification equipment has a very small pore size, and the osmotic pressure of the aqueous solution is used to separate water molecules and impurities to achieve a thorough purification of water quality. So here is a brief introduction to the installation process of small industrial reverse osmosis water purification equipment. Installation process of small industrial reverse osmosis water purification equipment: 1. Punch holes or fix ultra-pure water equipment at selected positions. The hole should be smooth, the depth and distance between the holes should be accurate, and the hole circumference should not have cracks, nicks, or burrs. 2. Connect with the water pipe. First close the main tap water valve and connect the ultrapure water equipment. The interface should be wrapped with raw tape to prevent water leakage. 3. Connect the concentrated water discharge port. The pure water machine can put the sewage pipe directly into the sewage pipe, and leave a certain space at the port to prevent sewage from flowing into the direct drinking water equipment and prevent the 'siphon' phenomenon at the sewage outlet; if the sewage pipe of the direct drinking water equipment is directly put into the sewage pipe, A ball valve should be installed at the end of the sewage pipe, which can be opened from time to time to discharge sewage. The sewage pipe can also be directly connected to the original tap. The sewage pipe and the sewage outlet of the direct drinking water equipment must be connected properly to prevent water leakage. 4. Connect the purified water outlet and the purified water tap. If the flow rate is greater than 500 liters, you can directly use the 4-division pipe and the universal faucet; if the flow rate is less than 500 liters, you can choose to use the 4-to-2 connector to connect to the purified water outlet, and connect to the 2-division faucet through a 2-point white PE tube. When connecting the second pipe, first cut the pipe port flat, then put on the nut, then insert the pipe plug into the PE pipe, insert it tightly, insert the PE pipe about 1cm beyond the nut into the joint and tighten it. 5. Install the faucet: If you want to install the faucet on the sink, the stainless steel sink can be opened with a hole opener. If you want to fix the faucet on the wall, you can use the right-angle faucet hanger to fix the faucet on the wall. The connection method of the joint is the same as (4), and the fixed part must be tightened without shaking. 6. Open the total water inlet ball valve and debug the water purification device (see Maintenance and Maintenance for details of the debugging steps), and observe whether the joint is leaking. The observation period is 2 hours. A clean dry towel can be placed under the water purification device to check whether there is any Water seepage phenomenon. The operation precautions of small industrial reverse osmosis water purification equipment must be mastered by operators. Accurate operation and correct maintenance are the guarantee for the long-term stable operation of small industrial reverse osmosis water purification equipment. Next, I will take you to understand it accurately. Some precautions in the use of small industrial reverse osmosis water purification equipment. 1. Prevent the filter material from entering the reverse osmosis device: select the appropriate filter water outlet device to prevent the filter from leaking sand and activated carbon, and select the appropriate activated carbon to prevent de-powdering during use. 2. The water permeability of the membrane increases with the increase of water temperature, but high temperature will accelerate the hydrolysis rate of the membrane, and make the organic membrane softer and easier to compact. Therefore, for organic membranes, it is generally appropriate to control the temperature within the range of about 20-30°C. 3. In order for reverse osmosis to proceed, the applied pressure must make the pressure difference between the two sides of the membrane greater than the osmotic pressure difference. The choice of operating pressure depends on the concentration of the original solution, because it is related to the osmotic pressure difference. In addition, it also depends on the water permeability of the membrane and the water recovery rate. Generally speaking, increasing the operating pressure will increase the water production, but if the pressure is too high, the membrane will be compacted and the water permeation will decrease. 4. In order to avoid blocking the reverse osmosis device, the raw water should be pretreated to eliminate suspended solids in the water and reduce the turbidity of the water; in addition, it should be sterilized to prevent microorganisms from growing in the device. The above are the most important issues in the process of using small-scale industrial reverse osmosis water purification equipment. Cooperating with the maintenance of small-scale industrial reverse osmosis water purification equipment, the system can always keep running in the best condition to ensure the stability of water supply.
