It has recently become a problem with clogging the lines. There is no feed water mixed with ACH from tank to injection point or any other chemical. It is pumped directly from the bulk tank with a peristaltic pump to the injection point. We changed from Ferric Sulfate to ACH about 5 years ago...
We feed ACH as our coagulant and it seems to be scaling up our feed lines. The substance is hard, brittle, flaky red substance, has anyone else had this problem?
