    they will take care for your future.

Deammonification is an intensive treatment process for waste water containing high concentrations of nitrogen substances. The centrate from mechanical thickening, which contains over a thousand milligrams per litre of nitrogen, flows into the deammonification basins, which operate sequentially. A mixture of granulated and selected microorganisms at a regulated pH value and defined oxygen content, oxidise the ammonium-nitrogen into nitrite-nitrogen and then nitrite-nitrogen together with the remaining ammonium-nitrogen into gaseous nitrogen. The advantage of this process is the lower consumption of energy required for introducing air and the lower amount of an external carbon source, required in comparison to conventional processes.
