Uso de la Moringa oleífera como coagulante natural para la remoción de turbidez en aguas superficiales en los últimos 10 años: una revisión de la literatura científica

Synthetic coagulants can generate harmful effects on the health of the population, in addition to presenting high costs and producing a large amount of sludge. Therefore, the presentsystematic review aims to identify the percentage of turbidity elimination in surface waters of Moringa oleifera as a coagulant, according to research journals published in scientific databases, in the last ten years. For this, several databases were consulted, which were Alicia, Dialnet, Google Scholar, ProQuest, Readlyn, Renati, ResearchGate, ScienceDirect and Scielo. Where, 50 scientific investigations were selected, which were filtered by inclusion criteria until finally obtaining 22 investigations between articles and theses, from which the pertinent information to the study was extracted. It was achieved as a result, that the coagulant obtained from the seed of Moringa oleifera presents a high percentage ranging between 70% and 99% of turbidity elimination in surface waters. Despite the difficulty that arose when translating foreign articles, it was concluded that Moringa oleifera as a natural coagulant has high levels of turbidity elimination percentages in surface waters, especially if the seeds are adequately prepared to obtain the coagulant.
