DAGYEE Fine Screening Rotary Drum Filter System: Your Complete Solution for Advanced Solids Removal
Externally rotary fed drum screen description
The DAGYEE Fine Screening Rotary Drum Filter System represents the pinnacle of efficient and reliable solids-liquid separation for applications demanding superior effluent quality. This fully integrated, externally fed system is engineered to continuously remove fine particulate matter—down to 0.25mm, 0.5mm, or 1mm—from wastewater streams. More than just a screen, it is a packaged unit that often includes a self-cleaning drum filter, an integrated screenings compactor/dewatering screw, a control panel, and all necessary piping, providing a plug-and-play solution for precise filtration needs.
Externally rotary fed drum screen principle
-
Influent & Distribution: Wastewater enters the system and is evenly distributed across the entire width of the externally rotating drum via an adjustable weir or spray pipe.
-
High-Precision Screening: The liquid permeates through the fine stainless steel wedge wire or mesh panels. Suspended solids as small as 0.25mm are effectively captured on the drum's exterior.
-
High-Pressure Backwash: Positioned internally, a series of non-clogging nozzles direct powerful water jets onto the screen media from the inside out, dislodging all trapped solids instantly and continuously.
-
Screw Conveyor & Dewatering: The dislodged solids fall into a collection hopper and are transported by an integrated screw conveyor. The screw often functions as a compactor, pressing out excess water to significantly reduce the volume and weight of the waste for cost-effective disposal.
-
Clean Effluent: The filtered water collects inside the drum and exits via outlet flanges, ready for downstream processes or discharge.

Externally rotary fed drum screen advantage
High Flow Capacity & Robust Design: Optimized for large surface area screening, handling peak flows and shock loads with ease. Constructed from heavy-gauge, corrosion-resistant stainless steel.
True Continuous Operation: The internal self-cleaning mechanism operates concurrently with filtration, eliminating downtime for screen cleaning and ensuring consistent process performance.
Superior Solids Capture: Effectively removes a wide range of solids, from fine fibers to coarse particulates, with screen apertures available from 0.25mm to 6mm.
Reduced Downstream Burden: By capturing solids at the source, it significantly lowers the organic and hydraulic load on subsequent treatment stages like clarifiers, digesters, or MBRs, improving their efficiency and reducing operational costs.
Low Operational Overhead: Energy-efficient drive systems and optimized spray water usage result in lower lifetime operating expenses compared to conventional screening methods.
