Tratamento para reúso da água de lavagem de animais do frigorífico Frigobutiá do Município de São Pedro do Butiá

Abstract

Currently, with the water shortages, it is sensitive to concern and the search for procedures to reuse it safely, for the environment and especially for health. In the industries the area of effluent treatment is ample with the purpose of reusing it again in its production process. Thus, the objective of this study was to construct a Slow Pilot Filter, monitor its operation and evaluate the feasibility of implementing a real-scale Lentoem Filter for the treatment of animal washing waters from the Frigo Butiá located in the city of São Pedro do Butiá RS , in order to demonstrate that sustainable practices can be utilized seeking benefits for the industrial sectors, as well as for society and the environment. Daily analyzes were performed for the parameters of turbidity, pH, true color, conductivity and total and thermotolerant coliforms, and scraped the filter bed at the end of each filtration run. The filter removed up to 96% turbidity, up to 94.7% apparent color, conductivity was reduced up to 68%, and the pH remained between 7 and 8 at a temperature of 23 to 27 ° C. The removal of coliforms was up to 100% of thermotolerant coliforms and removal of up to 98% of total coliforms. This study shows that it is possible to install the Slow Filter in the FrigoButiá to clean the corrals, pens, corridors, cleaning trucks and other environments where water with a drinking quality standard is not required.
