Optimización de la Planta de Tratamiento de Agua Residual de la empresa Bioalimentar sector Pachanlica.

Abstract

This research aimed to optimize the Wastewater Treatment Plant of Bioalimentar Company, in Pachanlica, in the city of Ambato. This study started recognizing the area collecting and discharging wastewater. Then, flow measurement where sample and data were taken, water - flow that comes in the plant is 1.16 m3 / h. Plant procedure to purify wastewater in not so optimum. It has an activated system for sludge and bacteria were added to this water – flow, because the bacteria are able to purify wastewater by themselves. Formed floaters were towards a secondary sedimentation tank, so purified water goes to the bottom and has a disinfestation process, and generated sludge goes to bio- manager tank. After water characterization, it was observed that parameters of Suspended Solids (113.5 mg/L) Biochemical Demand of Oxygen (BDO) (480mg/L), Chemical Demand of Oxygen (CDO) (610mg/L), Total Coliforms, Fecal Coliforms are over the limits according to Unified Text of Environmental Regulations (UTER). It was concluded that analyzed parameters allowed determining components of treatment system to optimize economic resources which will have a manual grid system, a Flocculation- Coagulation, and a different doses of disinfectant to eliminate the pathogen agent, so it is reached the reduction of established limist such as: Suspended Solids (14 mg/L) Biochemical Demand of Oxygen (BDO) (237 mg/L), Chemical Demand of Oxygen (CDO) (237mg/L). it is recommended to implemet grid, Flocculation – Coagulation tank in order to manage and control contamination of liquids that are discharged to the dry place next to Bioalimentar Company.
