Abstract

The performance of an alternating pumped sequencing batch biofilm reactor process in synthetic diary wash-water treatment was studied. The system comprises two reactors with two identical plastic biofilm modules. Two centrifugal pumps, one connected to each reactor, alternately move the water from one reactor to the other one, resulting in aeration. At three loading rates (336, 501 and 1080 g COD/(m³ d)), total COD and total nitrogen were removed by 91-94% and 46-80%, respectively. Nitrogen was removed from wastewater by denitrification in the anoxic phase and Simultaneous Nitrification and Denitrification (SND) in the aerobic phase.
