AWWA WQTC71391

This powerpoint presentation begins by providing a brief overview of bioprocesses for drinking water treatment aspart of a multistage process, processes in fixed-bed bioreactors, and modeling approaches. Study objectives include the development and verification of a mechanisticmodel to study the behavior of filter columns with respect to bacteria concentrationsat media surface and in suspended phase. Experimental methodology included performing column experiments with differentcarrier media - apply Iwasaki-law, determining filtration coefficient (changes with attached bacteria concentration); setting up model for column behavior from mechanistic approach - Langmuir kinetics - attachment / detachment; determining coefficients -attachment and detachment rates, andmaximum attached bacteria capacity; and, comparing coefficients from column and batch(validation of model prediction). Includes tables, figures.
