Abstract
An environmental problem in Mexico and the world, is the domestic water pollution or wastewater with hydrocarbon derivatives, such as waste motor oil, a hazardous waste according to Ley General de Equilibrio Ecológico y Protección Ambiental and Mexican norms NOM-001-SEMARNAT-1996, NOM-002-ECOL-1997 and NOM-003-ECOL-1997, which set maximum allowable limits of concentration: 25 ppm of hydrocarbons for discharges of wastewater and national assets, 75 ppm of wastewater to urban sewage systems and 15 ppm for treated wastewater for public reuse, respectively, that when complying with these concentration values, prevent the treatment of such domestic water. An alternative solution is biostimulation, with detergent, minerals, and oxygen that induce the aerobic heterotopic microbial population of the water, to eliminate waste motor oil and its reuse. The objective of this work was the biostimulation of domestic water contaminated by waste motor oil and to decrease it to a value lower than the maximum of Mexican norms. For this purpose, the water impacted by waste motor oil was diluted and biostimulated with the detergent Tween 80, a mineral solution and hydrogen peroxide or oxigen through the response variables: i) production of carbon dioxide by waste motor oil mineralization, ii) determination of the decrease in waste motor oil concentration, by mass-coupled gas chromatography and by Soxhlet, the experimental data were analyzed by Tukey. The results indicate that the biostimulation of the water impacted by waste motor oil with the detergent Tween 80, mineral solution and hydrogen peroxide reduced it to a value of 10 ppm, a value lower than that established by the NOM-001, NOM-002 and NOM-003, which was derived from the mineralization of waste motor oil and which showed evidence of its disappearance according to the analysis by chromatography. The above showed the biorecovery of water contaminated by waste motor oil.
