WebThe dosages of FeCl 3 varied from 3000 mg/L to 4000 mg/L at a constant pH of 6. Meanwhile, the dosages of chitosan varied from 50 mg/L to 100 mg/L at a constant pH of … WebFeCl3 was found to be superior to other coagulants tested. At pH 4 and 12, fair removal of suspended solids was observed at a reasonably low coagulant dose, i.e., 600 mg L(-1); hHowever, about 2500 mg L(-1) of coagulant was required to achieve good removals at pH 6. Better removals were achieved at higher temperature.
