Coagulation and flocculation are the basis for water treatment, for the separation of solid-liquid mixtures, as well as a means of reducing turbidity. In the following investigation, the effect exerted by the speed and applied dose of aluminum sulphate Al2(SO4)3, as well as that exerted by the ferric chloride FeCl3-flocculant, was evaluated. To obtain the experimental data, a "Jarra Test" kit was used, performing tests at 06 applied dose levels (1, 2, 3, 4, 5 and 6 mL), and at 05 levels of agitation speed (100, 150, 200, 250 and 300 rpm). The results report that the best conditions, with Aluminum Sulphate, were achieved with a dose of 120 mg / L and at a speed of 100 r.p.m. of fast mixing and 25 r.p.m. slow mixing, decreasing the initial color of 213 UPC to 10 UPC, an initial turbidity of 66.6 to 1.1 NTU, an initial Fe (II) concentration of 1.37 to 0.05 mg / L and a pH decrease of 6.6 to 4.20. In addition, using a dose of 80 mg / L ferric-flocculant chloride, they demonstrate that the appropriate stirring speed is 200 r.p.m. fast mixing and 50 r.p.m. of slow mixing, because it has allowed to reduce the color up to 12 UPC, the turbidity up to 11.30, the iron concentration up to 0.20 ppm, but a decrease in pH up to 6.50 was observed. The statistical evaluation shows that, if there is a significant difference when using aluminum sulphate, as well as when ferric-flocculent chloride is used, so its use, if it has an effect in reducing the concentration of Fe (II).
