Experimentación práctica de una planta de tratamiento de aguas residuales para la lavadora de autos Octopus ubicada en la av Manuelita Sáenz del cantón Ambato

Abstract

The present experimental work executes the construction of a wastewater treatment plant, inside “OCTOPUS” car wash located in Manuelita Saenz Avenue. In order to validate the design of the treatment plant, the verification of the flow of the washing machine was carried out, once it has determined that the existing flow is similar to the design flow the construction process started, it was executed in 10 working days. The wastewater treatment phases in operation are: screening, sedimentation, grease trap, grease storage and an unconventional phase which comprises a 3-stage filter, each stage has a different filter material: peat bed, volcanic pyroclast and activated carbon, materials that were selected based on past thesis works and were the most efficient among a group of several filter materials. The operation of this treatment plant will be evaluated through 4 chemical tests to the water, which are: DBO5, DQO, Suspended solids, Oils and fats. The tests are taken with samples taken both at the entrance (influencer) of the PTAR and at the exit of it (effluent). The results obtained in the wastewater treatment plant have an accuracy of 83%, the oils and fats parameter meet the limits established by the TULSMA.
