Treating leachate from landfill and waste dumps is a growing environmental concern and BioGill technology can remove/neutralise a great variety of toxins such as dioxins, benzene and aromatic hydrocarbons.
Potentially, leach water can be reused as irrigation for sporting fields and other such uses. In treating the leachate with BioGills, energy costs associated with aeration can be significantly reduced.
Major benefits
1. Quick odour removal
2. Effective sulphide removal
3. Effective de-nitrification
4. Self-optimising and robust
5. Low energy and low maintenance

Quick odour removal
Most other biological treatment processes require the aeration of the treatment ponds. This creates increased aerosols and draws the odour forming compounds into large volumes of air, causing massive peaking in odour.
These aeration systems are expensive to operate and maintain and have problems delivering any significant oxidation of ammonia.
With BioGills, effluent movement is contained within the enclosed bioreactors. The bacteria and fungi in the biomass are extremely efficient and quick at removing the sulphides and volatile fatty acids that create the odour problems. Movement of air in and out of the BioGill is small, reducing odour spread.
Effective sulphide removal
Very rapid sulphide oxidation in the waste stream assists in odour control and allows the biomass to fast track the nitrification process.
Effective de-nitrification
The biomass effectively and quickly removes excess nitrogen and converts various nitrogen compounds such as ammonia to plant friendly nitrates suitable to promote tree growth when reused for irrigation.
Self optimising and robust
As leachate concentration varies over time, it is an important attribute of BioGills that the biomass quickly adjusts to deal with the make-up of the food source in the leachate. Heavy metal concentrations will not impact on the performance of the BioGill system.
Low energy and low maintenance
With minimal to zero maintenance on the treatment cores and very low energy consumption, BioGills are inexpensive to operate.
