Description of a dairy industry effluent: treatment proposal

Thayná Nunes Borges, Raíssa Miranda Costa, Hebert Medeiros Gontijo


Industrial activities generate too much effluents which, if not treated properly, generate pollution and damage to water resources, which makes environmental requirements severest. The project proposes to a dairy industry, specialized in the production of cheese bread, an efficient treatment of effluents, technically and economically viable of its waste generated in the process that is currently launched without treatment in nature, with a high pollutant load characteristic of waste from the dairy industry. For this, bibliographical surveys were carried out on the subject of effluent treatment, application of a questionnaire in the company and the physico-chemical characterization of the generated effluent with the purpose of elaborating the design of the Vermifiltro. Thus, the result of this work is the complete design of the treatment system that was proposed to the industry, composed of the results of laboratory analysis, sizing calculations, low plan of the implantation site, as well as the schematic design of the Vermifiltro. Therefore, Vermifiltro appears as an option to remedy environmental pollution, as well as showing itself as an efficient and economically viable technique in relation to conventional treatments, since the release of tailings in water resources directly affects its quality, changing its characteristics originates and causes in several imbalances, which evidences the necessity of the implantation of a treatment system.
