YMX Filter designs and manufactures rotary drum screens (also called rotating drum filters or drum sieves) that provide efficient, automatic separation of suspended solids from liquid streams.

Rotary Drum Screen Applications

Rotary drum screens are widely used for solid-liquid separation in industrial and municipal systems:

Wastewater treatment: removal of leaves, fibers, grit, and suspended solids before biological treatment.

Food & beverage: pre-screening of effluents in meat processing, dairy, or canning plants.

Chemical & process industry: separation of solid particles from process liquids.

Water intake & cooling systems: prevent debris from entering pumps or pipelines.

Mining and mineral processing: coarse solids removal and slurry pre-screening.

Design and Operation

The drum is a rotating cylinder fitted with wedge wire or perforated screen panels.

Liquid flows through the drum surface, while solids are carried along by rotation.

Scrapers or brushes remove accumulated solids from the drum surface.

Optional backwash spray system reduces clogging.

Designed for continuous operation with minimal manual intervention.
