PROVEN EFFECTIVE AGAINST GREASE AND GRIT
In 2004, the City of Monroe, Michigan participated in a "cleaning project" initiated for the purpose of raising awareness of the city's grease problem within commercial business concerns such as car washes (wax) and restaurants (grease). Prior to the project, influent sewer lines were chemically treated to break down the accumulation of grease, wax and similar solids in successive stages. As was typical, one FlexRake in the city's 6 ft. channel was in operation for the project.

Unexpectedly, grease, wax and other solids hit the plant nearly at once, creating a "grease attack" at the headworks. This "attack" overwhelmed the conveyor, but the FlexRake continued as normal, removing several inches of grease and debris with each pass at the screen. The FlexRake maintained head works operations; when the crew returned the following morning, they found plant processes continuing uninterrupted.
