Resumen
The present work had as objective to identify the possible sources of contamination by Iron and Manganese of groundwater used in industry of the metalomechanical sector, as well as the characterization of the liquid effluent and the evaluation of the effluent treatment system. In addition to proposing indications to the existing treatment system. In the identification of possible sources of groundwater contamination and in the evaluation of the effluent treatment system, physical and chemical analyzes of water and effluent were carried out. Between December 2017 and April 2018, samples of water and effluent were collected at three sampling points, totaling 15 samples. The parameters were analyzed: pH, apparent color, turbidity, total manganese and total iron, BOD, COD, oils and greases, sedimentable solids, phenols and surfactants. The investigation indicated as possible sources of groundwater contamination a fracture in the artesian well lining, in addition to the existence of an inadequate solid waste deposit. The evaluation of the effluent treatment system, characterized as Water and Oil Separation, indicated that the system is inefficient, the treated effluent does not meet the launch criteria established in the legislation. The suggestion of adequacy is the substitution by existing treatment system for a physical-chemical treatment process followed by biological treatment.
