This research project addresses the problem of pollution generated by municipal effluents from the San Jerónimo district slaughterhouse. These effluents contain pollutants such as organic matter, nutrients, and a high suspended solids content, increasing turbidity levels and posing a risk to public health and the environment. The main objective of this research is to evaluate the coagulant-flocculant capacity of mucilage extracted from sanky (Corryocactus brevistylus) and qaspio (Browningia viridis) to remove turbidity from these effluents. The methodology employed consisted of six laboratory tests to determine the optimal dosage (0.75 g/L, 1.00 g/L, and 1.25 g/L) of mucilage from the aforementioned cacti, evaluating its effectiveness in removing turbidity. The technique used was physical-chemical analysis of the effluents before and after treatment, and the instruments used included turbidity measuring equipment and laboratory analysis to determine the contaminant parameters. The results demonstrated that both mucilages are effective, achieving parameters that meet environmental standards associated with turbidity and total dissolved solids. However, the natural coagulant from the sludge mucilage achieved better results. At a dose of 0.75 g/L for a period of 25 to 30 minutes (including 5 minutes of rapid agitation, 15 minutes of slow agitation, and 10 minutes of sedimentation), it achieved 87.98% turbidity removal, a 37.94% reduction in electrical conductivity (μS/cm), and a 35.45% reduction in total dissolved solids (TDS, ppm).
