Diseño de una planta de tratamiento de agua proveniente del lavado de autos en la lavadora “La Unión” en el sector La Joya

Abstract

This paper makes the design of a treatment plant water from the car wash in the washing machine "La Union" in the La Joya, same investigative work that wastewater from effluent carwash was characterized in terms chemical and physical parameters defined by standards, the results of laboratory analysis gave the pH was 8.72 being within the parameters mentioned the TULSMA Book VI Table No. 8. the oils and fats are a high level where <0.98 with the maximum 0.3; total solids is 1438 mg / L while the law a ceiling of 1600 indicated; COD indicates a ceiling of 500 mg / L However, 2779 mg / L was obtained. The BOD5 has a limit of 250 mg / L and exceeding these levels with 943.59 mg / L. The TPH obtained is 264 mg / L and the maximum allowed is 20 mg / L; suspended solids are 726 mg / L being up to 220 mg / L. chemical, physical and biological processes that require water to be reused in the process carwash same starting at, then Grit, the Flocculator, the primary Settler, the aeration tank, secondary settler, drying eras and ends with the process of chlorination was established, which give proper pH level and water purity.
