Waste treatment systems are well known sources of foul odours. The most prevalent of these are hydrogen sulphide (H2S), ammonia and volatile fatty acids.

Hydrogen sulphide is caused by the anaerobic digestion of sulphur containing compounds by bacteria. The organisms produce these dissolved sulphides and release them into their aqueous environment. Water has a saturation point for sulphides and when the point is breached the sulphides are liberated from the water in the form of H2S gas.

OT200 was developed to eliminate and control malodours originating from waste water and sludge storage lagoons. The product works on three levels to eliminate odours.

The first is to introduce microbes that use the malodorous compounds produced by anaerobic bacteria as a food source for their own growth and in so doing eliminate these before they are released into the air.mechanical desludging was postponed

Secondly, anaerobic bacteria that are responsible for the majority of malodours, grow and reproduce more slowly than the facultative aerobes present in OT200/400. This means that if the aerobes can be applied in sufficient quantities, then they will out compete the sulphide producing bacteria for food.

Thirdly, the microbes present in our product will work to reduce organic waste in the system and in so doing affect the anoxic environments that support the growth of the sulphate reducing bacteria.


  • Malodours are formed in areas of the sewer where anaerobic conditions occur. The are generally characterised by areas of low flow like rising mains, pumping ‘wet wells’ or sumps and storage tanks used to balance the sewerage plant.
  • Food processing waste handling lagoons
  • Animal waste sludge and storage basins
  • Domestic septic tanks and grease traps
  • Effluent ponds in piggeries, poultry farms, abattoirs and dairy producers
  • Sewage pump stations and sludge handling facilities.


  • Eliminate the unpleasant odours and the impacts of these on the public.
  • Reduces hydrogen sulphide (H2S) induced corrosion of metal and concrete in waste treatment works. (H2S is a precursor for the formation of sulphuric acid)
  • Removes already formed H2S and ammonia compounds from the system.
  • The product reduces foul odours at source and does not mask the symptoms.
  • Improves safety by reducing H2S which is considered toxic.
  • Reduces BOD and the composting of organic wastes.
