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 microorganisms to grow. No need for expensive aeration. 

Reduced operating costs

Lower energy consumption with minimal maintenance requirements. 

Reliable and durable

Long system life. BioGills operate under atmospheric pressure and are constructed from highly durable materials. The membrane unit has no moving parts.


A BioGill system can deliver savings of +40% on the overall build, energy use savings of +50%, as well as maintenance and repair savings of +50%. ROI on a BioGill system depends on discharge rates applicable to each water control jurisdiction. In high cost areas, an expected payback can be between 18-24 months. 

No aerosols and quiet

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 replaced by healthy new biomass every few days. The attached growth style ensures no issues with sludge bulking or pin flock sludge. The sloughed off sludge settles extremely well and can be collected from the bottom of the recirculation tank.

No filters

BioGill treatment cores contain no filters which could foul easily and are expensive to replace. The membranes function as a medium for the biomass to grow and for the nutrients to diffuse through.
