CHARACTERISATION OF WASTEWATER FROM THE MOZAMBICAN BREWERY: CHARACTERISTIC COMPARISON WITH BREWERY EFFLUENTS FROM OTHER COUNTRIES

Abstract Wastewater from the brewery industry has complex characteristics and is a challenge for environmental engineers in their search for treatment and reuse. The main objective of this study is to compare the physicochemical characteristics of wastewater from the brewery industry in Mozambique and South Africa. The choice is due to the large volumes of water used by the brewery industry in its production processes, as well as the effluent management model that must be adopted. For this study, samples were collected and their physical and chemical parameters analysed. The results were compared with different breweries industries in other countries in the area, the legislation in force in Mozambique and the values estimated in the different articles considered in the literature. With the results obtained, it was possible to characterise the wastewater from the brewery industry in Mozambique in order to find the best method of treating these effluents in a more environmentally friendly way.
