Chemical Contaminants Assessment Influencing the Proper Funcntioning of the Waste Water Treatment Plant in a Brewing Factory: Case of SABC Yaounde -Cameroon
Journal of Geography, Environment and Earth Science International,
The present study were carried out in the brewing factory of Cameroon (SABC) Yaoundé focuses on the evaluation of chemical contaminants influencing the wastewater treatment plant.
Standard methods of analysis of physicochemical parameters of wastewater in anaerobic sludge were done according to Waterleau .
The information collected made it possible to evaluate chemical contaminants according to the use of water, water solubility and dangerousness.
It was found that, chemical contaminants are mostly disinfectants (30%) and cleaning products (15%). Nevertheless, there are others used for pH regulation, such as beer stabilizers, etc. The wastewater treatment plant has shown overall good yields. The temperature that varies between 31°C and 32°C, characterise an optimal temperature for the metabolism of microorganisms. The pH oscillates between 7 and 10 characterise majority the alkaline waters. This study shows that the presence of chemical contaminants in discharge water which came from different part of the factory and were other chemical are used, influences microorganism area and can affect their health of purification microorganisms by acting on the physico-chemical parameters of wastewater and sludge.
