Our subsidiaries

Denkgrün GmbH

Sewage sludge recycling for raw material recovery, energy storage and energy generation

In 2015, pro aqua started with the electrochemical treatment of processed biogenic waste. Years of research and development work have led to the development of a process for the recovery of raw materials (e.g. phosphorus, nitrogen) and energy generation from biogenic waste. Denkgrün GmbH was founded in 2020 and entrusted with the technical and economic implementation.

Chlorine-free pool water treatment

In 2008, the first prototype of an electrochemical cell with boron-doped diamond electrodes was presented to the world market leader for hot tubs. The latter recognised the potential of the diamond electrode and the automatic disinfection of the pool water. Two years of technology development were concluded with the founding of DCW – Diamond Clear Water GmbH in 2010, which is responsible for the production and distribution of this exclusive niche product.
