Abnormality in circulating water
Thread Content
After adding scale inhibitors to the circulating water in our company, there is a lot of yellow foam on the surface, and the turbidity rises above 40; the water quality does not improve even after several days of replacement.
Change the scale inhibitor and enhance wastewater discharge
If the yellow foam appears only after adding a scale inhibitor, it is best to contact the manufacturer to find out what’s going on.
The turbidity is high; I’m not sure if you have added any biological scale-removing agents or other chemicals. The yellow foam might be a result of organic phosphorus compounds and other substances combining with those already present in the water, as a consequence of the addition of scale inhibitors. It is recommended to analyze the reasons based on the water quality report.
Most circulating water scale inhibitors are acidic; it is presumed that corrosion is occurring in your case. The increase in yellow foam is caused by iron ions resulting from corrosion, and the rise in turbidity is also due to this reason. It is recommended to add a corrosion inhibitor, replace the water, and consider changing the scale inhibitor! My WeChat is Azsyx1314; we can communicate there
Does the first half of the sentence mean that too much scale inhibitor was added?
Test to check if the iron ion level is above the limit? Is the scale inhibitor added in accordance with the required dosage?
Does the circulating water have a bypass filter? Under normal circumstances, the turbidity increases after adding a sludge remover, but it’s strange that the situation doesn’t improve even after several days of replacement.
To check for any material leakage into the circulating water, it is also possible to contact the chemical manufacturer to find out where the problem lies. .
