| Abstract | The anaerobic filter has proved to be an energy saving waste
treatment technology, having a complex mechanism.
The objective of this study was to formulate a fundamental
model for the substrate removal in anaerobic filter, to be used
in its design.
This study was conducted in lab-scale unit using synthetic
waste, with glucose as the main carbon source. The variations
were made in influent COD concentration, hydraulic retention time
and the surface area of the filter media used.
Engineering models were developed using best-fit model
parameters. Further, design charts were developed for practical
applications, for the percent COD removal with hydraulic loading
and the height of filter media column.
The Contois kinetic model was used to compare experimental
and t h eoretical results. This model justified the comparison at
low organic loadings in the range of 0.125 to 1.5 kg COD/(m3.d ) .
The theoretical values deviated widely at higher organic
loadings. |
