EVALUATION OF THE COAGULANT EFFICIENCY OF MORINGA SEED (MORINGA OLEÍFERA) FOR THE WATER TREATMENT OF THE CHURÍN RIVER, PACHANGARA DISTRICT, LIMA, PERU

Abstract

Background: In the research, Moringa Oleifera - MO seeds were used in coagulation-flocculation processes, identifying the main properties it presents such as coagulant activity. Aims: The purpose of the research was to evaluate the coagulant and flocculating effect of moringa seed flour in the treatment of turbid water (with turbidity between 700 NTU and 800 NTU). Methods: The experimental tests were carried out under the following conditions: shelled moringa seed flour in NaCl solution, 1 M, it was observed that it has no effect on the clarification of turbid water and modifies the pH to 4.47; The mixture of moringa seed flour with aluminum sulfate (Aquapol brand) was investigated in jar tests with 300 mL of turbid water at conditions of: shelled moringa seed flour 1.02 g, 5.01 g and 10, 02 grams; with aluminum sulfate 0.1 mL, 0.5 mL, and 0.7 mL, respectively; at 200 rpm for 2 minutes, Results: Evaluating water quality after 1.5 h and 12 h of sedimentation; It was determined that the best performance was the mixture of: 1.02 g of moringa seed flour with 0.1 mL of aluminum sulfate, 200 rpm for 2 minutes, then at 70 rpm for 15 minutes and 12 h of sedimentation. Discussion: Experimental tests have been carried out using Moringa Oleifera (MO) for raw river water treatment processes in places of low economic availability and due to its abundant availability, low cost, and non-toxic. Conclusions: It was concluded that its most viable application would be as a flocculation adjuvant, since, when used with a Chemical coagulant, it reduces the concentration of the chemical coagulant with good removal results.
