Estudo de caso para uma possível modificação no tratamento de efluente de uma fábrica de tio2 para um processo de precipitação de íons férricos.

Abstract

he water crisis and the need to optimize the industrial processes, regarding the reduction of environmental impacts in the generation of effluents, inherent to the chemical processes used in the production of titanium dioxide by the sulfate cycle, justifies a better improvement on the subject in question. The aim of this paper is to present a case study to evaluate an alternative for the treatment of the effluent of a titanium dioxide processing industry, aiming to reuse the residual water of a proposed unitary process in whole or in part. would precipitate the largest possible amount of ferric ions, which is the main contaminant of this effluent. With the implementation proposed by this case study, through a theoretical analysis and with its due unitary operations, there will no longer be a need to dispose of the effluent at sea, reducing the environmental impacts inherent to this process and reducing the expenses in the production of water processed in the production process, since this, in parts, will be provided by the process proposed here in this article.
