Proposta para implantação de um sistema para tratamento de efluente líquido industrial

Abstract

In this day and age, one of the main issues surrounding society is the concern towards the preservation and use of natural water. Industries are currently the biggest contributors of pollution towards water resources. Debris include; high concentrations of dense metals; such as Iron, Chrome, Nickel and so forth...Other pollutants include substances which could contaminate the water, thus posing a threat to human health and marine life. Industries strive to control such impacts which might also affect other living organisms through the ‘Sistemas de Gestão Ambiental’. A case was brought up about a study towards a company that deals with metals and mechanics (location: Contagem). It focused on the methods adopted by the company when it comes to handling water with waste material. After analysing the data received (accompanied by the lab analysis of waste matter in the water), elevated levels of oil, DBO, DQO, sediments due to suspension, an alteration in the pH levels, Sulphates, Zinc. Thus resulting in the decision that internal action must take place to minimize waste materials found in the water and improve the filtration process. The suggested changes have not yet been implemented due to the fact that there is no data about the efficiency of the proposed solution.
