Drum Sieve
Fine Filtration for Low Flow Rates
Drum Sieves are designed for the efficient removal of fine solids from wastewater.
The Drum Sieve operates on an external-fed principle, retaining solids on the outer surface of the rotating screen while allowing the screened wastewater to pass through. The drum, constructed from specially designed wedge wire screen panels, efficiently captures suspended solids, reducing the pollutant load on the wastewater and contributing to the reliable operation of the treatment plant.
The system consists of a gear motor drive unit, a rotating drum, a scraper blade, and a backwash system. Its compact design allows it to be manufactured in a wide range of capacities to meet project requirements. All components are manufactured from stainless steel to ensure excellent corrosion resistance and long service life.
Thanks to its simple design and continuous screening capability, the Drum Sieve is an ideal solution for low-capacity preliminary treatment applications.

Frequently Asked Questions
What applications are Drum Sieves best suited for?
Drum Sieves are particularly well suited for low- and medium-capacity wastewater treatment plants and applications requiring compact fine solids removal. They are an ideal solution for industrial wastewater treatment, packaged treatment systems, and installations where space is limited.
How does the Drum Sieve prevent clogging?
When solids accumulate on the screen surface, the integrated backwash nozzles are activated to clean the screen. The continuous rotation of the drum, together with the scraper blade system, further reduces material build-up. This ensures uninterrupted screening performance while minimizing the risk of clogging.
