A systematic review. Efficacy of natural coagulants in the treatment of domestic wastewater.

Abstract

The objective of this article was to describe the efficacy of natural coagulants, as well as to explain their removal power compared to aluminum sulfate and to identify the best natural coagulant for turbidity removal in domestic wastewater treatment; For this, a qualitative research design was followed, collecting 50 articles, using inclusion and exclusion criteria. As results, the natural coagulants showed a great efficiency in the reduction of turbidity, varying from 23.07% to 98.69%, likewise there is a similarity between the natural coagulants and aluminum sulfate, being the most advantageous and natural ones. at the same time, it was recognized that Moringa Oleífera is the most effective in removing turbidity. In Conclusion, natural coagulants reduceturbidity between 23.07% and 99.60%, in turn, natural coagulants and alum have a high similarity, with turbidity levels between 53.85% and 99.44%. and 70%. at 98.69%, finally, Moringa Oleífera, eliminates higher levels of turbidity, with values between 53.85% and 99%.
