Wastewater from car washers and lubricators produces effluents with high concentrations of oils, greases and detergents. A fraction of these pollutants form an emulsion in water, which when solubilized increases the organic load in parameters such as TOC, COD and BOD5; these emulsified effluents are not separated by primary systems such as grease traps. In order to evaluate the contamination, a simple sampling was carried out in 61 washing machines and lubricators in the city of Ambato. With these data, a representative sample of 95% of the total establishments was created in the laboratory; the non-emulsified fraction was separated by means of a primary treatment and the soluble phase was treated with a suspended bed activated sludge reactor. In order to improve the nutritional relation of the residual water of mineral origin, a suspended bed of sugar cane was clucked in the aeration tank.
