    The present experimental project show a process and analysis of a filtering material for the pretreatment of wastewater from a car wash industry, so taking as an alternative the use of crushed brick, with which it is reduced to levels of contamination of the effluent , in a 90-day monitoring period. For this, it is necessary to determine the important parameters of the industry, as well as the requirements of income or consumption, know the infrastructure and operation of it; also determining the filter design for a flow rate of 0.105 lt/min of daily consumption. The sampling during the filtration process determined the efficiency of the material, it was done every 10 days and at the same time taken to the laboratory for analysis; the results obtained revealed the decrease in pollution levels, from initial values of oil and grease contamination (246 mg / l), COD (2715 mg / l) and BOD5 (1328 mg / l O / l) , until final results of (0.11 mg / l), (1258 mg / l) and (624 mg O2 / l) respectively after filtration. The results of the analysis of the filtered samples showed decreases in the levels of pollution levels; The efficiency of crushed brick to treat oils and fats is very evident. The crushed brick is a material that possibly manages to treat oils and fats in its entirety, presenting an efficiency value of 99.96%, thus satisfying the limits proposed by the TULSMA for this parameter; Similarly, for COD and BOD5, the efficiency values are 65.75% and 70.86% respectively, reducing pollution levels, but not satisfying the limits proposed by the norm described above.
