New automated grease trap designed by Aerofloat.

Aerofloat installed its Aerotrap at Goodman Fielder bakery – a unique automated grease trap.

The Need

Goodman Fielder was looking for a pre-treatment step to take some of the load off its existing wastewater treatment system.

The Solution

Aerofloat installed its unique Aerotrap, which uses a similar automated sludge removal mechanism as its patented dissolved air flotation (AeroDAF). The Aerotrap is effectively an automated grease trap, which has ensured a simple solution for removal of fats, oils and grease (FOG) from the wastewater.

The Benefit

Goodman Fielder was provided with a simple, maintenance friendly and effective solution that has taken significant load off the existing wastewater treatment plant.


Goodman Fielder is a leading regional food company across Australasia.

It manufactures, packages and distributes a number of products from various sites around the country.

Goodman Fielder in Moorebank, Sydney, is a bakery producing garlic bread.

An increase in production meant that the existing wastewater treatment plant was unable to handle the heightened load of FOG in the wastewater. Goodman Fielder looked for a pre-treatment step to lessen the load on the existing plant.

The Aerofloat Solution

Aerofloat installed its Aerotrap and several other process steps to manage the removal of solids and grease, high wastewater temperatures, plus the transfer of the treated wastewater to the main plant.

Aerofloat’s engineers’ experience in grease trap wastewater treatment designs meant it was able to meet the client requirements quickly and effectively.


Aerofloat introduced a pre-treatment phase to remove a large proportion of fats, oils and grease (FOG) from the wastewater. This ensured Goodman Fielder’s existing wastewater treatment facility did not become overloaded and remained compliant.

After Care Service

Aerofloat can help you maintain optimal performance of your wastewater treatment system long after installation.
