Aerobic wastewater treatment with integrated deammonification

Aeration plant with integrated deammonification

ALMA BHU BIO DEA

Our ALMA BHU BIO DEA was specially developed for industrial wastewater with high ammonium concentrations. Thanks to the combination of partial nitritation, anammox reaction and efficient sludge separation with recirculation, the system achieves low-energy nitrogen elimination of up to 95 %.

The system works without an external carbon source and requires up to 60 % less oxygen, which significantly reduces operating costs. The aeration system is individually adapted to the type of wastewater and customer requirements to ensure stable and efficient performance.

Advantages

Up to 60 % less energy consumption - Thanks to partial nitritation, the ALMA BHU BIO DEA requires significantly less aeration and therefore up to 60 % less oxygen. This leads to significantly lower operating costs and optimum energy utilization.

No external carbon source required - The process works completely without an external C source, as energy-intensive complete denitrification is bypassed. This reduces both operating costs and process complexity.

Significantly lower sludge production - Thanks to the slow growth rate of the anammox bacteria and the efficient use of biomass, noticeably less excess sludge is produced than in conventional activated sludge systems. A clear advantage for maintenance, disposal and plant dimensioning.

Over 50 % less space required - Compared to conventional biological reactors, the ALMA BHU BIO DEA requires more than 50 % less space. The compact, modular design also allows easy integration into existing plant structures.
