Grease & Skimmings Removal: Scum Concentrator
The Walker Process Equipment Scum Concentration System is a low-maintenance and easy-to-operate system that reduces the cost of processing skimmings removed by clarifiers. The system is specifically designed, engineered and constructed to reduce the volume from water, fats, oil, grease and other material from clarifier skimmings that would otherwise be introduced in to the digester – the elements that promote foaming, degrade performance and increase treatment costs
The system is designed for dewatering and homogenizing the grease and skimmings (typically from the primary clarifiers) and concentrates the mixture to a total suspended solids concentration of approximately 50%.
Two steps provide dewatering as scum is first pumped through a grinder to a rectangular separation tank that is provided with a chain and flight collector to skim the greasy material for discharge to one or two day tanks. Second, the day tank is used for storage and equipped with heating elements and a mixer to further reduce the moisture content of the collected scum or grease.
The system consists of a flotation (separation) tank and a preparation (day) tank with mixer and electrical controls. Optional accessories include a grinder, scum concentrate (grease) pump, and access platforms.
