Treatment of ion exchange resin "Iron poisoning"

Ion exchange resins have the advantages of good chemical stability, high mechanical strength, large exchange capacity, making them widely used in water treatment for power plant boilers, industrial boilers, the production of desalinated purified water. However, during the use of resin, it may be contaminated by harmful impurities such as iron compounds organic compounds, leading to resin poisoning accidents. Drilling mud additives

If reasonable measures are taken in a timely manner to revive it, it may cause resin failure even scrap. The phenomenon of resin poisoning iron poisoning is common. Our company's years of production practice have provided methods preventive measures for dealing with this type of resin iron "poisoning" accident. The surface of ion exchange resin is covered by iron compounds the exchange channels inside the resin are blocked by iron impurities, which significantly reduces the working exchange capacity regeneration exchange capacity of the resin, but the resin structure remains unchanged. This phenomenon is called iron poisoning of the resin.

1. Analysis of pollution reasons: There are four main reasons for resin iron poisoning:

① The water source is groundwater with high iron content surface water contaminated with iron;

② The internal corrosion of the inlet pipeline exchanger has resulted in the formation of iron compounds;

③ The regenerant contains iron impurities;
