Abstract
This study investigates the performance of laboratory pond system
containing immobilized cells of Saccharomyces cerevisiae in the
treatment of raw tannery wastewater as compared to a pond system
without cells. The performance of the pond system was evaluated by the
measurements of BOD, COD, sulphate, TS, chloride, pH, chromium and
cadmium. Also, the hydraulic characteristics of the pond configuration
such as the average retention time and flow rate were estimated.
The results obtained indicated that the system containing the immobilized
cells yielded better results in the reduction of some of the parameters
when operated under the same hydraulic and organic loadings. For
example, the overall BOD, COD and chloride removal were 73.5%, 62.96%
and 69.56% respectively. Also, chromium and cadmium respectively
attained a reduction of an average of 96.21% and 53.77%.
Using statistical tools in further analyzing the results showed that the
immobilized cells of s. cerevisiae are solely responsible for the reduction of
the parameters.
