A novel moving bed biofilm reactor has been developed, where the biofilm grows on small, free floating plastic elements with a large surface area and a density slightly less than 1.0 g/cm3. The specific biofilm surface area can be regulated as required, up to a maximum of approximately 400 m2/m3. The ability to remove organic matter from concentrated industrial effluents was tested in an aerobic pilot-plant with two moving bed biofilm reactors in series and a specific biofilm surface area of 276 m2/m3. Treating dairy wastewater, the pilot-plant showed 85% and 60% COD removal at volumetric organic loading rates of 500 g COD/m3h and 900 g COD/m3h respectively. Based on the test results, the moving bed biofilm reactors should be very suitable for treatment of food industry effluents.

A flexible pilot plant, fed with primary settled wastewater, was used to study (1) organic carbon and nitrification in a two(three)-stage continuous-flow aerobic process and (2) organic carbon and nitrogen removal in a heterotrophic moving-bed sequencing batch biofilm reactor (MBSBBR) for denitrification and in a continuous-flow autotrophic moving-bed biofilm reactor (MBBR) for nitrification. In both experiments the same polyethylene biofilm carriers were used. Filtered COD removal rates in aerobic conditions appear to be proportional to the corresponding loading rates up to 8 gCOD m−2 d−1. Nitrification tests, performed in oxygen limiting conditions and ammonia limiting conditions, showed that the reaction rate was nearly first order with respect to dissolved oxygen due to liquid film diffusion. Denitrification tests, performed without external carbon sources, showed that the denitrification rate never fell below 0.3 gNO3−-N m−2 d−1 even at very low biodegradable filtered COD loading rates.
