Residue Found in Softener Valve Head
Residue Found in Softener Valve Head
(OP)
My plant recycles process water from a zinc phosphate line.We do a flocculation and settle procedure and run the resultant clear water through a bank of softeners followed by carbon filters. The softened and filtered water then gets run through our RO unit. During troubleshooting of a problem, we found calcium phosphate residue (flakes) in the valve bodies of the softeners. We also found the softener media bed granules to have been infiltrated with a similar substance (TBD) to the point where media had to be replaced. What could cause a problem like this? Is our treatment system just not sized for the amount of phosphates and hard water salts that are present?
