Rotary Disc Sieve

Precision Screening for Reduced Process Load

Rotary Drum Sieves are designed for high-efficiency filtration of wastewater containing fine particles, particularly fibrous materials.

Wastewater flows through stainless steel screen panels mounted on the rotating drum, where suspended solids are retained on the sieve surface while the filtered water passes into the outlet chamber. The retained screenings are continuously removed by a pressurized spray wash system, which cleans the screen surface and flushes the collected solids into the discharge hopper.

Rotary Drum Sieves are available in capacities ranging from 10 to 400 m³/h, with screen openings from 150 to 1,000 microns, depending on the treatment capacity and wastewater characteristics. All components, including the screen panels and structural frame, are manufactured entirely from stainless steel.

Thanks to their design, filtration and screen cleaning take place simultaneously, ensuring continuous and uninterrupted operation.

Frequently Asked Questions

What applications are Rotary Drum Sieves best suited for?

Rotary Drum Sieves are high-efficiency filtration systems designed to remove fine suspended solids, particularly fibrous materials, from wastewater. They are especially well suited for industrial wastewater with a high fibrous content and for applications requiring reliable fine screening.

In Rotary Drum Sieves, filtration and automatic screen cleaning take place simultaneously. A pressurized spray wash system continuously removes accumulated solids from the sieve surface, ensuring uninterrupted operation while minimizing the need for manual cleaning.
