    Biofiltración sobre cama de turba, para el tratamiento sobre agua residual proveniente del lavado de jeans

    The present experimental work has to objective design and build a prototype of a biofilter on peat bed, for the treatment of the residual water from the Jeans washing. The biofilter was constructed with recycled materials such as: water bottles, plastic meshes and biodegradable materials such as virusa. The general scheme of the filtration column was to establish a layered structure consisting of the following: First layer: virgin, which serves as the distribution material of the inlet water of the waste water. Second layer: Constituted by the peat, is the main layer of filtration. The properties of the peat (adsorption, absorption, ion exchange, porosity), help to purify the residual water from the Jeans washing. Third layer: consists of river sand, serves as support material, and auxiliary purification. Fourth layer: Pumice stone, which allows a better discharge of treated wastewater, and serves as a support material. The process was performed for 36 days, with a number of 10 samples analyzed. Data collection was performed before and after biofiltration, to establish changes in coloration. For the analysis of the physicochemical parameters, we proceeded to take the samples and take them to the laboratory in a maximum of two hours, in order not to alter the results. With the database, analyzes and calculations of the efficiency in the purification of the residual water were carried out, obtaining the following results: DQO = 76.69%, DBO5 = 75.27%, ST = 57.33% efficiency, which allowed to establish criteria of Design and to determine that the peat has high efficiency for the purification of the residual water from the washing of Jeans
