How does a Big Dipper Work?

Big Dippers automatic grease removal devices have internal tanks certified to separate and retain grease just like other hydromechanical grease interceptors,
but also have skimming assemblies which isolate the retained grease into a collector allowing for easy daily maintenance without another company to clean it.
