This study has as a goal to compare the efficiency of the coagulant solution made from extract of Moringa oleifera seeds with two industrial coagulants very disseminated in the Market, for treatment of the water from Apodi/Mossoro river, relative to its pattern of potability. Moringa oleifera can present a big contribution for water treatment, because the seeds can be used in the process of clarification and reduction of the harmful compounds in it. The monitored treatment system was done in a Jar test equipment using 1,5 L of the water samples. The concentrations that had shown the best results for each coagulante system wer: 2,5 and 7,5 mL (Moringa oleifera solution), 7,5 and 10 mL (solution of ferric chloride), 5 and 7,5 mL (solution of aluminum sulfate). The samples were made in triplicate. The analysis were made in a 24 hour sedimentation break, and the parameters evaluated were turbidity (NTU), aparent color, nitrite (NO2), ammonia (NH3) and pH of the samples.
