Drumtec: Internally Fed Drum Screen


Drumtec is an internally fed rotating drum screen built for heavy pretreatment applications such as draining, mud thickening, and sandy or industrial wastewater treatment. This product is highly recommended for membrane bioreactor (MBR) treatment plants.

Drumtec is an internally fed rotary drum screen with a pinion-and-rack driving system. It provides high reliability with minimal maintenance, and little user involvement in daily operation.


1. Simple and Reliable Machinery
The gear motor drives a pinion-and-rack system, which rotates the drum. Made of HDPE (High Density Polyethytylene), the mechanism does not require any maintenance (left).

Oversized trunnions support the drum, and provide stability during rotation (right).        

2. High Capture Rate
Because the drum is fed internally, Drumtec catches all sorts of debris such as rocks, grits, organics, wipes, rags, fibers, and the like. The perforated plate provides a high capture rate of materials as small as 800 microns, making Drumtec a great solution for fine screening, specifically with a MBR system.   

3. Safe & Easy Access
The cover is equipped with a lift handle on each side of the drum. A hydraulic assist mechanism allows a single operator to open the cover. A safety switch automatically stops the drum.         

4. Integrated Bypass
An integrated bypass is available. If equipped, a sensor stops the drum, and the overflow routes to a tank containing a manual rack.        

5. Minimal Maintenance
Spray bars provide touch-free cleaning of the inside of the drum. Weekly maintenance consists only of a visual inspection of the drum and the spray bar nozzles. Nozzles are easily removed for cleaning or replacement, when necessary.        

6. All-In-One Solution
For complete screening treatment, a washer/compactor can be integrated directly at the discharge chute of the drum screen.
