Elaboração de um manual para o controle de qualidade da solução de sulfato de sódio

Abstract

The process of neutralizing sulfuric acid and sodium aluminate from automotive batteries and anodizing processes generates a large amount of liquid waste, after the process of separating the precipitate through pressing. This residue is of great interest for the recycling process, as it has a high percentage of sodium sulphate, thus evidencing its use for its reuse as a raw material for manufacturing in the glass, textile and cellulose paper industries. For the commercialization of some products, the parameters are used, and must be applied through the manual of good practices, to the quality control of the residue, avoiding environmental contamination. In this context, the work aims to build the procedure manual for the analysis of waste following standardized processes of low operating cost, which was applied in a small / medium-sized industry, with a consultation with employees and entrepreneurs for validation of the methods for its use, use to preserve the environment, facilitating the procedures that trainees and analysts will carry out with the help of the manual, and also in the development of improvement in the production of products manufactured by the company.
