Abstract:

A study was carried out from December 2016 to February 2017 with the aim of   evaluating the effects of some coagulants (Aluminium sulphate, Moringa, Starch) on the effluent discharge of the Etoudi slaughterhouse and the Ako’o River which receives these waste products. Monthly water samples surveys were carried out on these two zones and physico-chemical analysis were done following the recommendations of Rodier and his collaborators. The effluents of this major slaughterhouse in the city of Yaounde are highly charged with diverse polluting substances and bacteria. The effects of aluminium sulphate, Moringa, Aluminium sulphate mixed with starch and Moringa mixed with starch were tested on these samples. Microbiological analyses on the other hand were carried out following the spread on the surface of a petri dish containing the culture medium of the water samples after successive dilution. On the bacteriological plan, the reduction rate offaecal coliform, total coliform and Escherichia coli were greater than 95% for the different bio-engineering techniques employed. As for the physico-chemical parameters, the rates of maximum reduction at 70%, 68% and 56% were obtained for the colour, turbidity and suspended particles respectively. Treatments realised with the addition of starch represented a higher efficiency as compared to that realised with sulphate and Moringa only.
