Grease and Scum Removal
Grease and scum removal is a routine operational task that affects effluent quality, odor, and downstream equipment performance if neglected.
Grease and scum removed daily from clarifiers and aerated grit chambers prevents buildup that affects effluent TSS and downstream equipment (UV disinfection, filters).
Scum handling facilities (scum troughs, pumps, concentrators) require regular cleaning and inspection — a stuck scum pump quietly creates a much bigger scum cleanup later.
Skipping scum removal on a slow shift because 'it's not a big deal today' compounds quickly — a daily small scum removal is far easier than a once-a-week large one.
Track scum volume removed per day as an operational indicator — increases can signal upstream changes (industrial FOG discharge, collection system issue) before they show up in other process trends.
