The use of conventional chemical coagulants for wastewater treatment, its harmful effects on the environment, and the risks associated with public health have attracted particular attention to develop biocoagulants obtained from the mucilage of plant species of interest. This project proposed using Malva sylvestris, a weed in different crops in the municipality of Chalchihuites (Zacatecas, Mexico), as raw material to produce biocoagulant by extracting the mucilage present in its leaves and its application in the clarification of domestic residual water. Through an experimental design 2^2 for this biocoagulant, the optimal pH (range 4 - 10) and optimal dose (range 50 - 450 mg/L) were determined to achieve the highest percentage of turbidity removal in the study water coagulation-flocculation processes using jar tests. The results allowed identifying the optimal conditions through a significant linear model, identifying that the maximum percentage of turbidity removal in the studied water was 73.71 %, whose optimal conditions were the dose of 50 mg/L a pH of 10 of the residual water used and with an average initial turbidity of 75.21 NTU for the wastewater used. For this reason, Malva sylvestris could be used as a raw material for the sustainable development of technologies for wastewater treatment since it does not generate toxic by-products, nor does its use represent a risk to the environment and human health and reduce the presence of this invasive species in the ecosystem
