SEMENTE DE MORINGA OLEÍFERA COMO COAGULANTE NATURAL NO TRATAMENTO DA ÁGUA

Abstract

Moringa oleifera (MO) seed extract, a plant native to northern India, can be used as a natural coagulant to reduce turbidity, color and microorganisms in the treatment of raw water and gray water. It acts as a coagulating agent that contains cationic proteins in its structure, which consists of agglomerating and sedimenting the impurities present in the raw water for clarification. Thus representing an alternative to problems related to the consumption of non-potable water in areas lacking water treatment and rural areas. It has low cost, is easily produced and biodegradable, that is, it does not produce toxic waste like conventional coagulants. Thus, a bibliographic search was carried out using search sites such as scielo, google scholar, pubmed as well as books and manuals published in the last 20 years about the use of Moringa oil seed in the treatment of water for supply. It has been observed in several studies the efficiency of it considerably reducing the turbidity and microorganisms of raw water as well as in the reuse of gray water, making it a sustainable and accessible option mainly for more needy and remote regions.
