Polishing resin

The polishing resin commonly used by people is generally used at the end of ultra pure water treatment systems to ensure that the effluent quality of the system can maintain water standards. Generally, the effluent quality can reach over 18 megaohms and has a certain control ability over TOC and SIO2. The ion forms of polishing resin that leave the factory are H and OH types, which can be used immediately after loading without the need for regeneration.

1. Polishing resin is a mixture of hydrogen type strong acidic cation exchange resin and hydrogen oxygen type strong alkaline anion exchange resin.

2. In homework, if water needs to be added for easy filling, please note that pure water must be used without too much water. At the same time, the water must be immediately pumped out or drained after the resin enters the resin tank to avoid resin layering.

3. If you need to manually load resin, be sure to wash your hands and do not bring grease into the resin tank.

4. If it is to replace the resin, the tank and collector must be completely cleaned, and there must be no old resin residue at the bottom of the tank, otherwise these used resins will pollute the water quality.

5. The O-ring used and the urgency must be replaced regularly. At the same time, relevant components must be checked during each replacement, and if there is any damage, they must be replaced immediately. Check the water collector, if there is any blockage, it should be removed.

6. When using FRP tank as a resin bed, the water collection pipe should be left in the tank before filling with resin. During the process of filling resin, the water collection pipe should be shaken irregularly, so that the position of the water collection pipe can be adjusted and the cover can be installed later.

7. If resin is loaded first, there will be difficulties in inserting the water collection pipe. If it is necessary to fill the resin before inserting the water collection pipe, the FRP tank that has been filled with resin can be placed horizontally on the ground, slowly rolling the barrel to loosen the resin, and then slowly inserting the water collection pipe into the resin.

8. After filling the resin and connecting the pipeline, the vent hole at the top of the bucket should be opened first, and water should be slowly introduced until the vent hole overflows and no more bubbles are generated. Then, the vent hole should be tightly closed and water collection should begin.
