Tratamento de efluente líquido da indústria de vidros com semente de moringa oleífera

Abstract

The use of biopolymers extracted from plants in the clotting process has several advantages compared with chemical salts. Among the advantages: low cost and variation in the nature of the alkalinity of the water in the process, because the sludge generated after treatment has lower volume compared with the sludge generated with the use of chemical constituents. The specific study of wastewater generated in the industry of glass quenching calls attention to the high rate of waste sludge. The effluent is a major concern regarding the disposal or reuse. In this case, the hardening process studied uses 110,000 liters of water per month, which generates 40 tons / month of solid waste and consequently large volumes of wastewater. During the study the objective was to check the behavior of Moringa oleifera seeds as natural coagulant in the effluent liquid from the glass industry and water reuse in the process.
