Özet

A novel biofilm reactor named as 'rotating perforated tubes biofilm reactor' was used for treatment of synthetic wastewater with and without liquid phase aeration. Effects of major process variables such as feed wastewater flow rate, COD concentration and loading rate, liquid phase aeration on the rate and extent of COD removal were investigated. Liquid phase aeration was proven to be advantageous especially for high strength wastewaters at high COD loading rates. Kinetics of COD removal was investigated and kinetic constants were determined by using the experimental data. An empirical design equation was developed to quantify the system's performance as a function of major process variables.
