    The objective of this experimental project is to evaluate the efficiency of sugarcane bagasse as a filtering material in the pretreatment of wastewater from a jeans washing machine, in a monitoring period of 90 days, during which time it is sought to reduce the levels of pollution levels of the BOD5, COD and color parameters. For this it was necessary to know and analyze the infrastructure and operation of the industry, as well as it was necessary to determine the flow of consumption and output. To determine the efficiency of the material, the collection and analysis of samples of raw wastewater filtered and filtered every 10 days randomly. The results of the raw wastewater analysis were; BOD5 (217mg / l), COD (620mg / l) and color (3860Uptco) while the lowest results of the filtered residual water were BOD5 (28mg / l), COD (66mg / l) and color (598Upt- co), comparing these values, a considerable decrease in the levels of contamination of the three parameters is observed. During the entire filtering process, a material change was made, since the results of the filtered water analysis approached the maximum values allowed by the TULSMA standard. With the results obtained, the efficiency of the material was calculated, obtaining the highest values on day 20 after having made the material change, where the efficiency was 87.10% in the removal of BOD5, 89.35% in the COD removal and 84% removal of color. In addition, the material was characterized using the scanning electron microscope TESCAN VEGA3, with which it was observed that this material has good adsorbent properties. Although the efficiency of the material did not remain high throughout the filtration process, it concludes that sugarcane bagasse is a material that can be used as a filter for the pretreatment of the effluents coming from the jeans washing machines, duringa 30 days’ time period.
