Ecologix Externally Fed Drum Screens are extremely versatile and can be applied to industrial wastewater systems with heavy solids loading and high flow rates. The screening cylinder can be configured with wedge wire or a perforated plate.
Influent is delivered to the screen through a pump or by gravity. A weir on the drum evens out the flow and presents it tangentially onto the screen surface where solid separation occurs. A set of internal and external sparge pipes with nozzles ensures the screen surface is maintained clean and free of solids build-up. The separated solids are scraped off the screen by a diverter plate where they are collected for further treatment or dewatering.
