The New Generation of fine screening

Next stage design for enhanced function and operational efficiency

Fine and Ultra-fine screening for municipal and industrial wastewater applications to protect efficiently downstream processes at highest capture rates and increased hydraulic capacity.

Unique Features

  • Highest screenings capture rate technology on market due to efficient flow path and panel media. (up to 85%)
  • Highest hydraulic performance available with the patented honeycomb panel
  • No accumulation of debris below the machine possible
  • Low maintenance with virtually due to less wearing parts
  • Improvement of downstream processes provides operational and maintenance efficiencies
  • Excellent retrofitting capability to existing channels to improve plant hydraulics and screenings capture efficiency e.g. fine screen or step screen replacement
  • Can be designed to accommodate channel dimensions and hydraulic requirements; highly suitable for deep channel designs


Passavant-Geiger/Aqseptence Group offers an efficient and space saving screening solution with a revolutionary drive concept. Contrary to the conventional technology, the Centre-Flo has a chainless drive with shaft and pinion on the clean outside of the screen belt.

The screen belt geometry and the large open area of the panels enables highest capture rate of screenings. Clean side and dirty side strictly separated, and so a “carry over” effect of solids on the clean water side are excluded.

With the curved honeycomb panels, Noggerath® ensures an exceptional performance in wastewater treatment. In addition, there are further innovative filter elements such as the flat honeycomb screening elements or the perforated panels. Both options can be made by additive manufacturing (recommended) or stainless steel (if required).

The nature-inspired honeycomb screening elements generate extremely high open area (up to 90%) and thus reduce the operating headloss and enable significantly higher throughput.
