Eficiencia de la semilla de mangifera indica mango de hilacha como coagulante orgánico en una muestra de agua residual doméstica

Proper wastewater management is essential to prevent contamination of the water component. This is why the use of organic coagulants has emerged as a promising alternative for the efficient removal of pollutant parameters in domestic wastewater. Therefore, the objective of this research was to evaluate the efficiency of Mangifera indica (Mango hilacha) seed as an organic coagulant in a sample of domestic wastewater by determining the effect on the parameters of turbidity, color, pH, total dissolved solids (TDS), settleable solids (SSED) and chemical oxygen demand (COD). The main methodology of the study is based on the application of the jar test for the determination of the optimum doses of the coagulant applied in different pollutant loads of domestic wastewater. For the preparation of the coagulant the mango seed was dehydrated for the first sample, taking advantage of solar energy, and then taken to a home oven, for the second sample it was dehydrated using only solar radiation, applying the #6 principle of Green Chemistry, then it was crushed, ground and sieved to finally prepare the solutions with concentrations of 0.5% m/v and 1% m/v. Finally, the best removal percentages were obtained for COD: 100%, turbidity 54% and SSED 1.2 ml/L sedimentation, these, in solution of the coagulant at 0.5% m/v with doses of 50ppm and 300ppm; on the other hand, for TDS 56% removal in solution of the coagulant at 1% m/v with doses of 300ppm. From the above, it was determined that the coagulant can be more efficient for pretreatment of wastewater or to refine it after a more complete treatment because its removal was better in waters with low and medium pollutant loads.
