Análise do tratamento de efluente gerado na fabricação de cerveja

Abstract

In beer production is generated a large amount of highly polluting discharges containing high organic load, sharp color and toxic chemicals to humans and the environment. Wastewater treatment is consisted in the technology use to adapt the residue to the standards of the Environmental Waste Legislation before being discharged into the environment by minimizing the environmental impact. The wastewater treatment stations have their own specific characteristics in accordance with the effluent generated by the industry. It is up to the effluent generator to ensure that it has an adequated end, investing in a treatment structure to make the production chain more sustainable. This study aimed to evaluate various process parameters of a WWTP, as well as its monitoring through analysis and data collection station, to allow tight control of physical and chemical characteristics of the effluents generated in a brewery factory in the city of João Pessoa, Paraíba. The study was conducted during January 2013. Samples were collected at four distinct points: lift station (raw wastewater), equalization tank, the reactor output and output facultative pond (final effluent). Were realized analyses of pH, temperature, settleable solids, COD and BOD. The results of the various parameters analyzed in this work show that the Brewery Effluent Treatment Station shows an excellent performance in the operating conditions tested, reaching values within the limits required by the laws of CONAMA (2005), so there aren’t any significant impacts to the environment.
