BioGill Advantages

The BioGill technology offers many advantages over existing wastewater treatment processes:


Above ground

BioGills are an above ground solution, so oxygen is freely available for the microbes to flourish. No need for expensive aeration. BioGills can also be positioned above potential flood zones.


Low operating costs

Very low energy consumption with minimal maintenance requirements.


Reliable and durable

Long system life. BioGills operate under atmospheric pressure and are constructed from highly durable materials.


Cost effective to install

Compared to existing technologies, BioGills are relatively inexpensive.


Produces little or no sludge

A BioGill system can be  can be configured where most, if not all the sludge, is cannibalised. Mostly, the sludge produced is predominately carbohydrate and biodegradable creating a highly effective fertiliser.


Silent with little or no odour

Pumps can be submerged to reduce noise. BioGills do not produce aerosols, so exclusion zone requirements are greatly reduced.



Older biomass sloughs off the gills and is automatically replaced by healthy new biomass every few days.


No filters

BioGill treatment cores contain no filters which foul easily and are expensive to replace.


No chemicals

No chemicals are required in most applications when treating to an irrigation or environmental discharge standard.
