Biological Scrubbers

For efficient removal of H2S, VOCs and other odours from air streams using controlled biological activity. 

Designed for high treatment efficiency, maximum corrosion resistance. Biological scrubbing action minimises chemical consumption and offers low ongoing operational cost. The biological scrubbers are built to designs by Marc Deshusses, Professor of Chemical & Environmental Engineering, USA. Marc Deshusses is a leading international researcher in biological techniques for air pollution control. 

Uses of Biological Scrubbers

  • Wastewater treatment plants for hydrogen sulphide and odour control 

  • Pumping stations for odour control 

  • Rendering plants for odour control 

  • Pulp & Paper plants for odour control 

  • VOCs (volatile organic compounds) 

  • Food processing plants for odour control

Types Available

We have a range of different Biological Scrubber types available to suit any application:

  • Vertical towers
  • Horizontal crossflow style
  • Combination "plug & play" units

Key Features 

  • Lower operating costs

  • Compact footprint

  • No hidden operating costs

  • Extensible

  • Corrosion resistant construction

  • Lower scrubber shell serves as integral sump for recirculating liquid supply 

  • Standard accessories including access doors, spray headers, piping connections, nozzles, internal structure supports, packing plates and hold-down lugs.

  • Circulation pump can be mounted on side of scrubber to minimise footprint

  • Nutrient dosing & storage componentry are optionally included

  • No complex controlling instrumentation. ph monitored only.
