Pumping technology Anröchte composting plant

Brief description of the project

Entsorgungswirtschaft Soest GmbH collects and recycles approx. 30,000 t/a of organic waste at the Anröchte composting plant. The existing composting plant was expanded in 2020 to include digestion. The tender was won by Hitachi Zosen INOVA AG for the digestion part. Finsterwalder Umwelttechnik in turn was allowed to supply and install the pump technology for circulation and transfer of the digestion product from the digester to the composting system. The pump capacity is adjustable between 12 and 22m³/h at 10bar delivery pressure.

Procedure in detail

Gate valve pump KS23

FINSTERWALDER SLIDER PUMP KS23 DN250
The two KS23 slide gate pumps are filled alternately from a DN400 pipe via a Y-piece.
One pump pushes the fermentation product back into the fermenter via a DN250 pipe. Both pumps
are operated simultaneously to continuously transfer the fermentation product into the compost mixer.
HYDRAULIC UNIT
The hydraulic unit specially developed for this project drives both pumps and can also operate
other valves on the system. It has a 600L oil tank, a WHG oil pan and consists
of three oil circuits.
control cabinet
CONTROL CABINET AND AUTOMATION
The control cabinet and automation were adapted for the project. The aim was to ensure 24-hour automatic operation
and remote access. In addition, the fermentation product should be sent to the
compost mixer as continuously as possible. For this purpose, frequency inverters were installed, which allow both pumps to be operated
in a coordinated manner.
