Grease Muncher – Model 800

The Allied Pumps Grease Muncher combines the conventional underflow grease arrestor design with a special Biofilter which dramatically reduces the grease content of the discharge through microbiological activity.

The Grease Muncher is a lightweight compact grease arrestor ideally suited for installation in both existing and new developments, particularly where conventional concrete grease arrestors are not practical or desirable. They can also be used for temporary installations or where relocation at a later date may be required.

Designed in the United States, the Biofilter has undergone extensive field trials in Australia and has been widely accepted by Australian Water Authorities.
