    The following research study is aimed at determining the processes that allow the improvement in the residual waters coming from the car washing machines of Ambato, province of Tungurahua. Thus, a field and experimental investigation is carried out that allowed to know the current state that present the washing machines that work in the city. The flow rates of 10 washing machines under study were determined as well as and the volume they occupy in the washing of three types of cars (cars, trucks, 4x4) From the field study of the ten washing machines, the volumes used in the washing of the three types of study for the determination of flow rates were obtained. The average output flow was 6.98 L / min, the average volume of water used in the car wash, truck and 4x4 is 88.52 L, 122.49 L and 113.90 L respectively. The physico - chemical parameters of the waste water coming from the washing of cars were analyzed in the laboratory of the Faculty of Civil and Mechanical Engineering of the Technical University of Ambato, obtaining results that exceed the maximum permissible limits of the TULSMA except for the sedimentable solids. Through an analysis of studies reported in the literature, it was determined that the efficient wastewater treatment processes from car washers are the implementation of screening, sedimentation, aeration, moringa seeds, secondary sedimentation, duckweed and filtration. For the selection of the appropriate filtering material, the thesis data made by students of the Faculty of Civil and Mechanical Engineering of the Technical University of Ambato is taken, being the gravel and activated carbon the optimal materials.
