Diseño de una planta de tratamientos de aguas miel de Kilamupi Café

Abstract

A wastewater treatment plant was designed specifically for Kilamupi Café honey waters, based on a filtration system, which is composed of limestone, gravel, sand and activated carbon. It consists in an applied research and raised design was experimental, by manipulating the variables. Hence, the laboratory analysis was carried out before and after getting sewage to the pilot-scale plant, using composite samples with three replicas thanks to the Standardized Method for Water and Wastewater Examination, 23ava. 2017 Edition. Furthermore, interview was used as technique, which is typical of the qualitative method. In the initial characterization, the following results were obtained: total nitrogen 199,15 mg/L, total phosphorus 11,63 mg/L, pH 3,8, total solids 4086 mg/L, BOD5 5358,66 mg/L, 44 Pt-Co for true color and 1150 mg/L for turbidity. After filtering the wastewater, it was possible to reduce the concentrations of each parameter with a flow rate of 0,5 L/s; total nitrogen was reduced by 98,61%, total phosphorus reached a reduction of 97,59%, BOD5 decreased by 97,55%. In addition, total solids decreased by 98,15%, true color became imperceptible in a 1/20 dilution, pH parameter increased to 7,58 and turbidity parameter reached a value of 26,83 NTU, whose values are within the limits established by current environmental regulations. Moreover, through studies carried out, it was confirmed that the physical processes(secondary) and the materials of the filter bed constitute a viable option for the decontamination of wastewater. Finally, for Kilamupi Café estate, a filtration tank was dimensioned with the following measurements: 1,17 m2 of cross-sectional area; 0,82 m high; 1,08 m wide, 1,05 m long and 0,93 m3 capacity for its further implementation.
