Escava ScreenPak Series

The Complete Package

Escava ScreenPak is designed to help reduce plant operating costs by dewatering rejected screenings and grit, significantly cutting disposal costs. Wastewater enters the system and passes through a fine screen, removing floating and suspended matter, then grit and heavy solids settle in the grit removal chamber. The grit transport auger moves the grit against the incoming flow, washing out organic material. The system is fully automatic with inbuilt controls and monitoring system, and is also provided with an emergency bypass which can be opened in the case of a power failure. Controls can also be linked to a central plant SCADA system for full integration.

Fat & Grease Removal

The Escava ScreenPak can be supplied with the optional integrated Fat and Grease removal system. The central low velocity zone is fitted with an aeration flotation and surface skimming system to effectively remove problem causing fat and grease.
