Diseño de tratamiento de agua para uso en la planta de lácteos Tunshi - ESPOCH

Abstract

The water treatment process was designed for use in the Tunshi Dairy Plant of the Polytechnic School of Chimborazo. With the deductive and inductive method: problems caused by low water quality were diagnosed, looking for the specific type of treatment according to the characteristics of the water, with the experimental method the physicochemical and microbiological characterization of water was performed, using gravimetric, volumetric and instrumental techniques, using: thermometer, pH meter, spectrophotometer, turbidity meter, conductivity meter and jar test, sampling was carried out by Standard Methods 2310. The results of the characterization outside the INEN 1108 drinking water standard are: Hardness = 288 mg/L, Alkalinity = 500 mg/L Nitrates= 16,100 mg/L, Phosphates = 0,740mg/L, Dissolved Solids = 722.9mg/L, and Total Coliforms = 108.6 CFU/100ml. The most efficient process to reduce the parameters outside the INEN 1108 Standard is based on: retention of large solids, chemical coagulation accompanied by flocculation, sedimentation of suspended particles and disinfection with sodium hypochlorite, this process has stages of: Roughing, Homogenization, Sedimentation, Filtration and Disinfection. It is concluded that the treatment process has an efficiency of: Hardness=31%, phosphates=66%, nitrates=12.5%, dissolved solids=30.83%, fecal coliforms=100%. This shows that the water quality complies with INEN Standard 1108. II. It is recommended to the Administration to implement this project, since the treatment process is the most efficient to improve the conditions of the water used in the plant's production process.
