BACKGROUND
In this evaluation, the coagulants ferric chloride and SuperFloc SD 2080 were studied, with the aim of comparing their effectiveness in water clarification processes. The study was carried out with different doses of coagulant: 3 ml, 5 ml, 6 ml, 7 ml, 8 ml, and 10 ml, subjecting them to flocculation, coagulation, and sedimentation processes. Jar tests, Imhoff cone settling tests, and settling column tests were also performed. To determine the efficiency of the coagulants studied for the jar test, the doses used were: 5 ml per two liters for ferric chloride and 6 ml per two liters for the SuperFloc SD2080. With the sedimentation column test, the results were determined by the isoremoval percentage curve. The sedimentation column test was carried out in two-time intervals, where the first two intervals were five minutes and the other intervals consequently were every ten minutes until reaching 120 minutes. By the time of 57 minutes, the percentage removal results of the coagulants were 83% for ferric chloride and 37% for the SuperFloc SD 2080, which indicates that the ferric chloride was more efficient for the removal of suspended solids in water.
