    The purpose of this experimental project is to evaluate the piroclasto volcanic as filter in wastewater treatment, by means physical-chemical analysis of the parameters under study, such as: Biochemical Oxygen Demand after 5 days (BOD5), Chemical Oxygen Demand (COD), and Oils and Greases. The efficiency of the filter will be reflected by comparing the results obtained in certified laboratories of environmental services with the maximum permissible limit values by the TULSMA norm prior to discharge to the public sewer system. The industry under study is a car washer and lubricator, where the biological filter was installed (in situ), in order to better collect the wastewater samples in established periods of time (every 10 days) during the 90 days of operation thereof. For the implantation of the filter a metallic structure was used where the tank and the plastic container containing the stored the wastewater and the filtering material were placed, respectively. The volume of the piroclasto volcanic that was used was 35 lt with an optimum flow rate of 0.105 lt / min. Once laboratory results were obtained and tabulated, a reduction was observed in the concentration of BOD5, COD and oils and greases with percentages greater than 99% for the first two parameters and 75% for the last parameter analyzed.
