Title in Portuguese
Minimização e reuso de águas em indústrias sucroalcooleiras: estudo de caso
Keywords in Portuguese
Efluente zero
Efluentes líquidos
Minimização e reuso de água
Sucroalcooleira
Abstract in Portuguese
Em conseqüência da constatação do consumo elevado de águas nas indústrias sucroalcoleiras, gerando efluentes líquidos que impactam o meio ambiente, considerando os avanços na implantação da cobrança pelo uso da água, este trabalho aborda várias alternativas de minimização e reuso de águas nas indústrias sucroalcooleiras, objetivando a redução da poluição na fonte e minimização da captação de água superficial, reutilizando os efluentes dentro do processo produtivo. Também são apresentados os resultados de um estudo de caso realizado em uma indústria, na qual foi realizada uma pesquisa do processo industrial, para determinar o consumo de água e a qualidade de efluentes e propor alternativas para minimização da captação de água e geração de efluentes.
Title in English
Minimization and reuse of water in sugar and ethanol industries: a case study
Keywords in English
Liquid effluents
Minimization and reuse of water
Sugar and ethanol industry
Zero effluent
Abstract in English
It is a fact that the sugar and ethanol industry in Brazil has a high level of water consumption and consequent production of effluents, with a negative impact to the environment. Also, the environmental legislation indicates a continuous raise in the charge for the usage of water from natural sources. As a consequence of the present situation, this work brings up several alternatives for the minimization and reuse of water at sugar and ethanol industries, aiming the reduction of pollutants at their source and the minimization of water uptake from the available supplies, by reusing the effluents inside the production process itself. It is also presented the results from a case study carried out in an industry where the production process was analyzed in the point-of-view of water usage and effluent generation. Alternatives for water uptake and effluent generation minimization are therefore proposed.
