The purpose of the present study was to estimate Cr(VI) removal through biological mechanisms in biofilm reactors operated in SBR operating mode with recirculation using different filter media types. The choice of the support material is of great importance since chromate reduction is followed by th

The efficiency of packed bed reactors on the biological degradation of phenol was studied in this work. In particular, the effect of the specific surface area of the support material and the operating mode on biodegradation efficiency were determined. Phenol removal was studied using two pilot-scale

Pilot scale trickling filters were constructed and tested in order to study biological removal of ammonia, iron and manganese from potable water. The effect of the size of the support material on nitrification performance was studied extensively. The mean size of the gravel and hence, the specific s
