Abstract
Abstract
Breweries are the traditional industry in agro and sector using cost effective techniques to manufacture the best quality product. Beer is a soft drink obtained through alcoholic fermentation, using selected yeasts of the genera Saccharomyces, of wort prepared from malt cereals, mainly barley, and other amylaceous or sugar-based raw materials. Most of the solid wastes and waste waters firms industries are discharged into the soil and water bodies and thus ultimately pose a serious problem threat to human and routine functioning of ecosystem. The main characteristics of environmental concern that can be associated with brewery wastewater include Biochemical Oxygen Demand (BOD)/ Chemical Oxygen Demand (COD) concentration, TSS concentration, pH, nutrients (nitrogen and phosphorus) concentration and temperature. Water pollution is serious problem globally involving the discharge of dissolved or suspended substances into groundwater, streams, rivers and oceans. A major source of pollution in developing countries is industrial activities and this has gradually increased the problem of waste disposal. Anaerobic bacterial degradation of organic matter (i.e. in the absence of oxygen), methane gas (CH4), carbon dioxide (CO2 ) and traces of other elements are produced. Aerobic biological treatment is performed in the presence of oxygen by aerobic microorganisms (principally bacteria) that metabolize the organic matter in the wastewater, thereby producing more microorganisms and inorganic end-products (principally CO2, NH3 and H2O).The overall result is a growing interest within the brewing industry in environmental pollution controls systems.
Keywords- Waste water, Ecosystem, Breweries, Chemical Oxygen Demand, Biological Oxygen Demand, Concentration, Total Suspended Solid.
