PO4 level has increased
(OP)
Our water treatment plant uses about 200Ibs of ZOP. recently, the po4 concentration in the distribution pipe has increased about 50% without changing of dosage. Is there any approaches we can take to narrow down the real cause of this? Thank you in advance.





RE: PO4 level has increased
IMHO, you probably should look at the whole process. The dosages for PO4 are not determined by a scientific evaluation, but by artistic expression and seat of the pants feel. 3-5 mg/l is probably not enough dosage to do anything.
Sort of like your automobile seems to work better after it is washed.
RE: PO4 level has increased
We have 15 sample locations through out our distribution system. The PO4 concentration at the entry point is 1.0 average, but the rest of the samples throughout the system have much higher concentration. Do you think we should flush the hydrants more often? Thank you
