The engelbart AB process was developed during decades of research through the combined collaboration of a team of international experts led by Dr. Wilke Engelbart  Based on past success with ponds, fish-farms, municipal and industrial WWTPs and experiences with highly toxic wastewater from chemical plants, etc., the disadvantages of known processes and equipment were eliminated and advantages were continuously improved upon.

The engelbart AB process is the latest improvement of the engelbart BioDopp process. It is a a 2-stage process that uses two different kinds of activated sludge.In the first stage (A) it is a special sludge for combination of biological phosphate elimination with pre-clarification of the raw wastewater. In the second stage (B),  consequently, a very limited load of a special nitrifying-denitrifying sludge results in an improved digestion of so-called hardly biodegradable residual components. It then results in drastic reduction of COD in the treated wastewater compared to “common” processes. Additionally – as desired – less surplus sludge emerges in the complete engelbart AB process. Compared with conventional methods that use a sludge recycling, the treatment capacity per basin-volume could be doubled.

Engelbart AB is very suitable for municipal wastewater treatment applications especially during winter months when the concentration of nitrogen compounds in the effluent is higher. The effluent from engelbart AB process can meet the water quality requirements for safe discharge directly into rivers and lakes.

The Engelbart AB process meets the highest demands in terms of:

• Treatment capacity per volume of the basin

• Minimizing the residual pollutants in the purified effluent

• Simplifying the operation, control and monitoring

• Operation reliability

• Minimizing energy consumption of the treatment process
