1.Use Care when performing backwashing
During backwashing, if the water flow is not adequate for the specific product or the operation is incorrect, resins may be washed out of the reactor and lost. This is the main reason why resins are found in trenches and waste water ponds.
2. Inspect regularly your vessels to make sure the nozzles or liquid distribution parts are intact
If the nozzles or other liquid distribution parts are damaged, the resins will leak out of the equipment, and then enter the subsequent equipment or water supply system. Therefore, the operation of the downstream equipment will be disturbed, and the quality of the produced water may be impacted.
3. Always monitor the quality and the amount of water produced. When operating Mixed Bed, select Seplite resin types allowing good separation of anionic and cationic component.
4.Prevent suspended solids from entering the ion exchange system.
If turbidity of the influent water is too high, it will lead to blockage of the resin bed, fouling of the resins and potential precipitation in the beads. The suspended solids often contain salts of multi-valent metal ions which are prone to precipitation.
5. When using sulfuric acid regeneration, prevent calcium sulfate precipitation:
Sulfuric acid is commonly used to regenerate the cationic resin. If the concentration of sulfuric acid is too high at the start and the flow rate is too slow, calcium sulfate will precipitate on the surface of the resin particles. To prevent this problem, a stepwise concentration increase of sulfuric acid during regeneration as well as sufficient flow are recommended.
Sunresin’s drinking water resins are produced with strict food-grade process, with all indicators meeting the food-grade standards and drinking water requirements, and have passed domestic and international safety and health certifications such as US WQA, EU food Grade certification, RoHs etc.
When the resins are contaminated with oil, the phenomenon of "clumping" occurs, and most of this pollution occurs in the cation exchange resins. The oil attached to the resins increases the buoyancy of the beads.
Anion exchange resins are susceptible to organic pollution. A good understanding of the typical signals of the pollution during operation can help regeneration and resuscitation in time. Its typical signals are as follows.
