Biological Systems

OSIL’s LavaRok biological systems are often the favoured solution for clients looking for a reliable and flexible solution for treating high volumes of odour – without the addition of chemicals.

Biological Systems

OSIL offers two types of biological treatment reactor:

  • Biotrickling Filters/Bioscrubbers

Odours are forced through a packed media bed colonised by microorganisms and the liquid medium is distributed uniformly. The odours are subsequently degraded by the microorganisms in the biofilm. Modes of recirculation and optimised contact between the odour and microorganisms are a key feature of OSIL offered biotrickling filters.

  • Biofilters

The gas is forced through a packed bed with an organic material on which the microorganisms colonise to form a biofilm, which degrades the odours.

Passive Filters & Tube Vents

OSIL are a leading provider of activated carbon-based, passive odour control units (OCUs), which are commonly utilised to adsorb vent gases from sewerage processes.

Passive Filters & Tube Vents

These high-quality ‘passives’ offer effective odour control and hydrogen sulphide removal, and are suitable for use with activated carbon in granular or pellet form.

The ‘passives’ offered by OSIL come with a disposable/refillable filter and can be mounted at the top of the pipe or at waist height.

We can deliver these in a range of construction materials and offer a bespoke design service to suit your environment. Disposable or fillable filters are available – as well as a powered vent option.

Our Passive Filter Systems can even be disguised as trees, bollards and lamp posts where odour control is required in sensitive areas.

OSIL’s Scrubbing Systems offer a number of key advantages:

  • Up to 99% removal efficiencies can be achieved in many applications
  • Can tolerate rapid & wide variations in odour concentration
  • Pressure drop across the system is the lowest in class
  • Low requirement for recirculation and make-up water rates
  • Easy to start up and shut down
  • Easy to monitor and control

Dry Scrubbing

OSIL specialise in tailor-made dry media solutions that do the work for you – whatever the specification, without any operator intervention required

Dry Scrubbing
