Abstract
As an important research area in drinking water treatment field, biofiltration and the mathematical modeling has received considerable attention. Butthe model does not match the experimental study. For designing the biofiltration process the practical model is not available. The objective of the study is to develop a representative model which simulates NOM (natural organic matter) removal in water treatment biofilter. A steady-sate model and the Monod-type substrate utilization were applied. The external and internal mass transfer was neglected in this model. The process of substrate biodegradation, bacterial attachment onto filter media and detachment of suspended bacteria was described. The NOM and biomass profiles in a biofilter as a function of filter depth and filtration velocity was simulated. Through a special experiment the key biokinetic parameters and Ks were estimated. Test and calculation results show that the model predictions are in good agreement with the experimental data. The model adapts to a wide range of various conditions by changing the parameters such as flow rate, bacteria and DOC concentration et al.
