The Grease Muncher GM700 is a compact grease arrestor designed to reduce fats, oils and grease from commercial kitchen wastewater. Combining a conventional grease interceptor trap design with a specialised biological filter, the system uses microbiological activity to significantly reduce grease content, suspended solids and biological oxygen demand (BOD) before discharge to trade water systems. Ideal for restaurants, cafes, commercial kitchens and industrial food preparation areas across Australia, the GM700 offers a lightweight and flexible alternative to traditional concrete grease interceptors.
The Grease Muncher GM700 has undergone extensive field trials in Australia and is suitable for flow rates up to 1000 L/hr, making it ideal for smaller commercial kitchens, restaurants and food preparation facilities.
Manufactured from a combination of polyethylene and thermoplastics, the unit is designed for long service life, durability and maximum corrosion resistance. The polyethylene chamber simplifies cleaning and helps reduce odours, as fats and grease are less likely to adhere to the internal surfaces.
The compact size and lightweight construction reduce installation and maintenance costs compared with traditional large concrete grease arrestors. This also makes the unit particularly suitable for leased premises, retrofit projects and applications where relocation may be required in the future.
Suitable for either above ground free-standing installation or below ground installation, the GM700 can be installed indoors, outdoors or even on rooftops thanks to its UV stabilised chamber and gas-tight design. Optional concrete cover slabs with cast iron gas-tight covers are available for below ground installations.
The Grease Muncher GM700 complies with SA Water standards for grease arrestors and provides an effective trade waste arrestor solution for commercial and industrial wastewater applications.
Available options include:
Key benefits of the Grease Muncher include:
Wastewater from commercial kitchens, restaurants and food preparation areas enters the grease arrestor through the inlet pipe and flows into the primary separation chamber.
As the flow slows within the chamber, fats, oils and grease separate from the wastewater and rise to the surface, while heavier solids settle below. The wastewater then passes through a specialised biological filter where microbiological activity further breaks down grease and organic matter.
This treatment process helps reduce grease content, suspended solids and biological oxygen demand before discharge into the sewer or downstream trade waste system.
The compact grease interceptor design improves wastewater treatment efficiency while reducing odours, maintenance requirements and grease accumulation within downstream pipework and infrastructure.
The GM700 is suitable for the following applications:
Periodic cleaning by a liquid waste contractor will be required to remove accumulated grease and solids.
A submersible pump is used to transfer water, wastewater or other liquids from one location to another, particularly where the pump can be installed below the liquid level.
They are efficient, quiet and reduce the risk of cavitation, as the pump operates while submerged.
Yes, 240 V pumps are available for standard electrical supply, making them suitable for many residential and commercial applications.
Options include stainless steel submersible pumps for corrosion resistance and heavy-duty materials for industrial use.
