Utilização de um destilador solar convencional para o tratamento de efluente de uma agroindústria

Abstract

Solar power, once held role of significant importance for humanity, this being a source of energy that offers many environmental benefits, in addition to being available in abundance and available throughout the planet. In agribusiness, water consumption in the production process is high, varying depending on the technology adopted in the process. As a result of the process is the origin of various by-products and / or waste which, appropriate allocation should be given, which requires compliance with current legislation. To conduct this study, it was necessary to build a solar still on a pilot scale with design, construction, operation and simple maintenance. Sought to propose and evaluate the technical feasibility of using a conventional solar still to treat the effluent of an agribusiness. The studies were carried out from September to October 2015 at the Federal Technological University of Paraná - Campus Mediatrix, which obtained a daily production around 0.800 L / m².dia considering rainy and sunny days. The physicochemical analysis, it obtained a COD reduction efficiency above 20% and a turbidity reduction efficiency above 80%. Concluding that the solar still is not indicated for the treatment of effluents of high volumes and constant generation..
