In the zeoReactor concept, natural zeolites serve as carrier material for the biology and settlement agent. The ion-exchange properties of the zeolites are the reason for their usage for decontamination of some captions in the water. Using specially modified natural zeolites one can control the ammonia content in the waters. The diffusion velocity of NO3- towards and into the zeolite is greater than the diffusion velocity of 02. It is therefore possible to create an controllable anaerobic environment required for nitrification Because of its large surface area for a settling of the micro organisms significantly higher biomass concentrations compared to traditional activated sludge processes are achieved which directly leads to a reduction of sludge generation. Through these effects, the zeoReactor concept will improve sludge settle ability to enable the plant to operate at a higher solids retention time and thereby improve effluent quality and/or increase plant capacity and enable nitrification to be established arid hence enable a reduction of nutrients discharged from the plant.
