Removal of Lead wastewater from the thermal stabilizer industry by chemical precipitation
Keywords:Lead, precipitation chemistry, water waste
This research pretend to show the remove the lead present in the wastewater of a thermal stabilizer industry. The chemical precipitation method was used, using a natural coagulant such as the nopal mucilage. The sample was obtained from the outskirts of the wastewater of the industry located 20 meters outside its facilities. The preliminary characterization analysis of the industrial process effluent was carried out to confirm lead contamination, which contained a lead concentration of 51.68 mg / L, followed by laboratory tests using a natural coagulant the mucilage of cactus, until achieving a considerable reduction, of 1.76 mg/L of lead in the residual water.
