What problems should be paid attention to when polishing resin filling in large-scale industrial ultrapure water equipment? Author: We know that polishing resin systems are generally used for large-scale industrial ultrapure water equipment end, to ensure the system is able to maintain water quality standards for water. Generally, the effluent quality can reach more than 18 megohms, and it has a certain control ability on TOC and SiO2. The ionic type of polishing resin is H, OH type, and it is directly used after filling without regeneration. So what should be paid attention to when polishing and filling large-scale industrial ultrapure water equipment? 1. The polishing resin is made of hydrogen type strong acid cation exchange resin and hydrogen oxygen. Type strong basic anion exchange resin is mixed. 2. During the operation, if water is needed to facilitate the filling, pure water must be used, and the water content must not be too much. At the same time, the water must be pumped out or drained immediately after the resin enters the resin tank to avoid the layering of the resin. 3. If you need to fill the resin by hand, be sure to wash your hands and do not bring grease into the resin tank. 4. For resin replacement, the tank and water collector must be cleaned completely, and no old resin remains at the bottom of the tank, otherwise the used resin will pollute the water quality. 5. The O-ring seal used must be replaced regularly. At the same time, the relevant components must be checked each time they are reinstalled. If they are damaged, they must be replaced immediately. Check the water trap, if it is blocked, it should be cleared. 6. Use FRP tank (fiber-reinforced composite plastic) as the resin bed, and the water collection pipe should be left in the tank before filling with resin. In the process of filling the resin, the water collection pipe should be shaken from time to time. At the end, the position of the water collection pipe can be adjusted and the upper cover can be installed. 7. If the resin is filled first, it will be difficult to insert the water collection pipe. If you must fill the resin before inserting the water collection pipe, you can place the FRP tank filled with resin horizontally on the ground, roll the barrel slowly to loosen the resin, and then slowly insert the water collection pipe into the resin. 8. After the resin is filled and the pipeline is connected, the vent hole at the upper end of the tank should be opened first, and water should be slowly introduced until the vent hole overflows and no air bubbles are generated, close the vent hole and start water collection. This is the end of the introduction about what problems should be paid attention to when filling large-scale industrial ultra-pure water equipment polishing resin. There are many issues that need to be paid attention to during the use and installation of large-scale industrial ultra-pure water equipment, and use it according to the points of attention.
