BioGill® Gill Structure

Key to BioGill® performance efficiency is the growth of healthy biomass on the patented nano-ceramic media, known as “Gills”.

These Gills provide the ultimate air and liquid interface for the microorganisms to grow, multiply and thrive. Wastewater is pumped to the clog resistant, patented HydroSwirl™ dispersal manifold, located at the top of each cartridge. Wastewater is then gravity-fed down through the cartridge.

The nano-particulate coating on the Gills, forms web-like structures that create a multitude of attachment sites for the biomass. This structure helps build thicker and more resilient biomass.

Arranged in suspended vertical loops, each Gill is folded over a support, creating two distinct sides: one in contact with the wastewater and the other in contact with the air. Oxygen diffuses within the biomass from the air side to the liquid side. At the same time, nutrients diffuse through the biomass from the liquid side to the air side. The process is known as counter diffusion and works 4 to 5 times faster than oxygen diffusion. This means BioGill® systems can be online, achieving treatment goals within days after start-up or system restart.

ANSTO developed, water and wastewater treatment plant

Invented and developed by scientists at the Australian Nuclear Science & Technology Organisation (ANSTO), this innovative technology challenges the traditional metrics and way of thinking in treating wastewater.

The technology is fundamentally different to conventional water treatment systems relying on submerged cultures and different to conventional attached growth processes where both nutrients and oxygen are supplied with the liquid from one direction.

The BioGill® technology allows for superior passive oxygen transfer, as gaseous oxygen is supplied directly to the biofilm from the atmosphere without traversing a liquid layer. This allows for greater oxygen fluxes and promotes treatment and energy efficiencies.

BioGill® key benefits


The BioGill® media fosters a biomass that is remarkably tolerant of fluctuations in wastewater flow and BOD & COD loadings. This is a key benefit for facilities with variations in wastewater producing activities over the course of the week or throughout the year, making these bioreactors equally well suited to year round or seasonal use.

The Gills achieve higher BOD & COD removal capacity through faster microbial community start up which is up to 7 times faster than conventional bioreactor technology. As such, substantial biomass re establishment can occur within 24 hours after a system shock, upset or system shutdown and restart, following a dormant period.

BioGill® technology can also treat a wide range of influent BOD & COD concentrations and tolerate levels of Fat, Oil and Grease (FOG) that challenge or disrupt alternative biological treatment systems

Highly effective

By providing the perfect oxygen rich habitat, the microbes perform at their best, protected in the biofilm and effectively removing pollutants from the wastewater. The BioGill® technology solves many of the shortfalls of other technologies by delivering effective treatment of high organic waste streams at low cost and low energy. The technology is also proven to reduce odor.

Low touch wastewater solution

BioGill® bioreactors are simple to install and easy to operate, with minimal maintenance requirements. No skilled wastewater treatment operator is required for the day to day maintenance and operation

Standardized, modular and scalable

BioGill® bioreactors are compact in design with a small footprint. This means units can easily be added as a customer s facilities expand.
