Fm. Samb et al., WASTE-WATER TREATMENT WITH BIOFILMS - ESTIMATION OF BIOKINETIC PARAMETERS USING A SEGMENTED COLUMN, Journal of chemical technology and biotechnology, 71(1), 1998, pp. 84-88
This study describes a technique for estimating biokinetic and mass tr
ansfer parameters for biofilm processes in wastewater treatment. The r
eactor used consisted of a column divided into separate units packed w
ith expanded clay pellets. Samples were taken at the exit of each unit
. Oxygen mass transfer and oxygen consumption rate were determined. Th
e system was operated with cocurrent upflows of air and industrial was
tewater. A mathematical approach was developed to estimate biokinetic
parameters such as the maximal oxygen removal rate, saturation constan
t and internal diffusion coefficient. (C) 1998 SCI.
