Waste water from breweries may contain a significant presence of organic materials from the raw materials used and a degree of acidity and alkalinity from the cleaning chemicals. The objective of this study was to evaluate wastewater samples from the brewing industry in terms of the following indicators: suspended solids, biochemical oxygen demand, chemical oxygen demand, ammonia nitrogen, total nitrogen. Data were statistically analysed by ANOVA single-factor method. The results demonstrated that quality parameters analysed had values below the limit.
