When the resin turns red, it is usually due to an excessive level of iron; please check whether the saltwater parameters are within the normal range:P
Excessive levels of iron and free chlorine in saltwater can cause the resin to turn red. This post was last edited by haining on 2009-2-11 12:22]
The effect of iron, the effect of free chlorine, dehydration also has an impact
There are two points of suspicion: 1. Excessive iron in the saltwater; 2. Free chlorine poisoning and resin failure.
It is usually caused by excessive levels of iron and free chlorine; prolonged loss of water can also lead to such effects. I have also encountered cases where salt sludge entering the chelation resin tower was the cause
1. Red-brown indicates an excess of iron, specifically ferric iron； 2. Pink is the effect of free chlorine ； 3. Additionally, it is also necessary to consider the situation regarding aluminum and silicates ； 4. It is recommended to conduct a comprehensive analysis of the primary brine.
It is likely that there are iron ions in the saltwater; it would be advisable to check the level of iron ions in the saltwater once, as well as the level of iron ions in the hydrochloric acid used to adjust the pH value of the saltwater. This post was last edited by yzhms on 2009-2-11 13:39.]
If it is the Kai membrane process, iron levels are likely to be too high; if no lumps form, it generally has no impact on the resin’s processing capacity.
If the iron level is too high, where is the iron coming from that ends up in the brine?
If the lining of the resin tower owned by the poster comes off, or in the case of the pipes for secondary brine, you’re probably using steel-lined pipes as well; if that lining comes off, it will lead to an excessive level of iron ions. So the key is to conduct an analysis of the saltwater parameters to further determine the cause.
It is usually caused by an excess of iron ions; once, the mother liquor was completely red.
Is it caused by potassium ferrocyanide, the anti-caking agent in salts?
Iron-iodine poisoning is mainly caused by an excessive amount of anti-caking agents in the raw salt
Check the analysis of saline, high-purity acid, and pure water; it is highly likely that excessive levels of free chlorine or iron are the cause. Take timely measures to avoid greater losses
