Resin plays an extremely important role in the operation of pure water equipment, as it can directly determine whether the effluent quality of the equipment is qualified. Regular inspection is required, so how to determine whether the resin has failed?

1. The good or bad ability of resin exchange in pure water equipment can be determined by simple monitoring of water output and quality (water detection) to determine whether the resin is ineffective.

2. Resin contaminated by iron environment, from the appearance, has a significantly darker color tone, darkening, and appears as a dull brown or grayish black. The compressive strength of the resin is reduced, and the water production rate at work is significantly reduced, making it difficult to rebuild; The reason for environmental pollution may be due to high copper content in water resources (0.3mg/L) or inadequate or decisive corrosion prevention of old steel water purification equipment;

3. Prevention measures caused by corrosion prevention: For water resources with high copper content, it is not allowed to immediately enter the air conditioning exchanger. Instead, it is necessary to first carry out iron removal equipment to solve the problem before carrying out ion exchange method.

4. Environmental pollution caused by specific permanganate index: High permanganate index (0.5mg/L) in water resources can lead to the destruction of resin structure. After poisoning, the resin color of pure water equipment will significantly fade, the clarity will improve, the volume will expand, and the compressive strength will sharply decrease. Resin crushing, but resin exchange volume does not decrease in the early stage.
