Test of natural coagulants extracted from Ipomoea incarnata and Moringa oleífera in the purification of industrial wastewater in Cartagena de Indias. Prospect. [online]. 2018, vol.16, n.2, pp.94-99.

Industrial wastewater needs to be treated due to the presence of impurities such as suspended solids, microorganisms, organic matter, minerals and others. One of the use of coagulants is one of the considered options to reach high levels of treated water quality and process performance is the use of coagulants. At present, the most common for water treatment are inorganic compounds that generate great disadvantages associated with high environmental costs and impacts. Therefore, within this research, the natural coagulants of Ipomoea incarnata and Moringa oleifera were evaluated using the soxhlet extraction method, compared to the conventional coagulants in industrial wastewater from ship sample and tannery, which generate consequences that directly affect of water sources to which they are discharged, obtaining results that confirm that Ipomoea incarnata and Moringa oleifera can be used as possible alternatives of natural origin in the purification of industrial wastewater, since also to guaranteeing the efficiency of removal of turbidity, they present characteristics of biodegradability that make it a viable alternative from the environmental point of view.
