EFFLUENT EVALUATION FROM CASTLE BREWERY FACTORY IN THIKA

Abstract

In this project sample of the effluent from four parts of castle brewery factory's efficient treatment plant.(L.T.P) were physically and chemically analysed.These four areas are sedimentation pond,j, aeration pond, maturation pond and the final effluent tanks.The analysis was carried out as per the given procedures which • were found to be the most accurate the final effluent which is being drained Into the nearby rivers after undergoing various treatment procedures is the one that determines the pollution extend of the brewery of the water courses and the environment in genera From the analysis and the experience carried during the research the average contributions of the following parameters were obtained tllOCl181illCdi oxygen Dernalld (BOD) Cllerlliccd uxygen Demand (COD) ~Ll lplll(lt; cunC81111 atl enl -rotal suspended solids (TSS) Potassium, 1<+ .

The above being major sources of water pollution, their values were noted to be far much above the recommended values for drinking water given by the World Health Organisation (WHO) eg the maximum level of BOD s should not be greater than 20 mg/l, comparing this to the BODs value of the final effluent of 343.3mg/l obtained, the level is far much greater. This trend also applies to the . other parameters whereby the set standard limits by W. H. 0 are very much below the values obtained from the analysis.
