CASTILLO COHAILA, Marcial Alfredo  and  AVENDANO CACERES, Edgardo Óscar. Effect of moringa seeds (Moringa oleifera Lam.) on the conditions for clarification of water from the sama river of tacna. Rev. Soc. Quím. Perú [online]. 2020, vol.86, n.1, pp.47-57. ISSN 1810-634X.  http://dx.doi.org/10.37761/rsqp.v86i1.272.

In the clarification treatment of the water from the Sama river water with moringa seeds from La Yarada Los Palos, an efficient removal of turbidity was achieved as a consequence of the removal of the suspended particles contained in the water of the Sama river in the rainy season. Therefore, the objective of the investigation was to determine the conditions for the treatment with moringa seeds in the clarification of the water of the Sama river using the test method of jugs with moringa seeds doses of 0,1 and 0,2 g/L; flocculation speed of 20 and 30 rpm and flocculation time of 20 and 30 minutes. The best operating conditions required for water treatment were: moringa seeds doses (coagulating agent) 0,2 g/L, flocculation speed 30 revolutions per minute (rpm) and a flocculation time of 30 minutes. Settling time of 90 minutes was established with water from the Sama River with turbidity levels of 132; 48,6 and 424 nephelometric turbidity units (UNT). Moringa seed was from the production of the year 2018 from the district of La Yarada Los Palos, with which a proximal composition of 5,70% Humidity was obtained (AOAC Method), 30,78% protein (Micro Kjeldahl Method ), 40,36% fat (Soxhlet Method), 4,42% ash (AOAC Method) and 18,74% carbohydrates (by difference). The experimental designs 23 and the randomized complete block design were used. Turbidity reduction levels of 97,04% were obtained; 92,37% and 98,88%.
