Where is permanganate fed?
Normally, the chemical is applied as early in the treatment process as possible. It should be fed at the intake to take advantage of the time and mixing in the pipeline to the plant. Ideally, all the permanganate will be used up before the coagulants and other treatment chemicals are added. The permanganate will oxidize raw water contaminants, thus allowing other complementary processes to finish the treatment and “polish” the water.
