PHYSICAL AND CHEMICAL CHARACTERIZATION OF INDUSTRIAL EFFLUENTS OF SORVETES AFTER APPLICATION OF FLOCULANTES
Journal Title: Periódico Tchê Química - Year 2017, Vol 14, Issue 27
Abstract
The dairy industry plays a major role both economically and socially in Brazil. However, it generates a significant volume of effluent that presents high organic load. Because of this, a proper treatment is required for the generated effluent, trying to minimize the environmental impacts of its disposal. One of the alternatives to make these wastes in accordance to the environmental standards is the use of flocculants and coagulants that are capable of neutralizing the negative charges, causing the particles to come together to facilitate the separation process. This study aims to analyze the efficiency of flocculants for the treatment of effluent from a dairy company located in the central region of the state of Rio Grande do Sul, in the Taquari Valley. The flocculants used were Aquafloc and Aquaflot. For this, the parameters of Oils and Greases, Sedimentable Solids and Chemical Oxygen Demand (COD) were tested. Similar results were obtanied with both flocculants. However, from the analyzed parameters, Aquafloc proved to be more efficient for removal of COD.
