Abstract
A new trickling filter model incorporating media geometries were compared to the predictions of the modified Velz equation. The two approaches predicted similar effects of hydraulic loading on sBOD removal. The model predicted slight improvements in sBOD removal with filter height, compared to large increases in sBOD removal using the modified Velz equation. The model also predicted a decrease in sBOD removal with increasing recycle, versus an increase in sBOD removal predicted by the modified Velz equation. The maximum aerobic sBOD removal capacity of a plastic media module was determined, although oxygen was not indicated to limit sBOD removal. A procedure was outlined for plastic media trickling filter design.
