The upgrade of chemical scrubbers to biotrickling is an innovative application in which traditional scrubbers are adapted at low investment costs.

The so-called “upgrading” of a chemical scrubber to biotrickling delivers the following advantages:

  • Operational costs are reduced considerably as the consumption of chemical reagents is no longer required, there is zero sub-product waste- which would otherwise require special treatment – and there is a considerable reduction in electricity consumption which is between two to five times lower.
  • Because chemical reagent deposits are no longer required, and smaller recirculation pumps can be used, the space available to install other applications increases.
  • Reliable efficacy and stability of the system is provided over time.
  • Due to the elimination of concentrated chemical reagents, working and environmental risks are reduced.
