Natural Coagulant Based on Mango Seeds (Mangifera indica L) in Removal of Turbidity of Domestic Wastewater

Abstract

The purpose of the research is to determine the turbidity removal capacity of a natural coagulant, made
from mango seeds (Mangifera indica L), which is applied in domestic wastewater taken from a local
treatment plant. The proposal of this technological, natural coagulation alternative is environmentally
viable due to its ability to mitigate the impact generated by a chemical coagulant. As method procedures,
the physicochemical characteristics of the mango seeds were determined, and the coagulation simulation
experiments were performed using the Jar Test technique. They were varying the influencing factors such
as the dose and concentration of the coagulant, thus obtaining the optimal six values that led to giving the
most significant removal of turbidity. Through the physicochemical characterization, the percentage of fat
matter 15.21%, humidity 7.60%, and ash 2.00%, it was determined that the optimal dose was 50 mg / L and
the optimal concentration 1% obtaining a turbidity removal percentage of 87.1%. The natural coagulant
based on mango seed powder can be used for the treatment of domestic wastewater due to its removal
capacity, and its low cost of elaboration compared with commonly used chemical coagulants.
