Corrosion Resistant Internally Rotary Drum Screen for Chemical Wastewater Treatment

Internally rotary drum screen description

It is an internally fed rotary drum screen that operates by dividing wastewater evenly with a deflector as it flows into the drum.

The flow then passes through a perforated plate, which screens solids from the water.

Waste materials are transported by a large flight auger to the end of the drum, where they are emptied into either a built-in washer/compactor or directly into a dumpster.

Internally rotary drum screen function

Wastewater enters the center of the drum and spreads evenly.

Solids adhere to the inner surface while clean water flows outward.

A set of pressurized spray nozzles knocks solids loose at the top for removal.

Both designs offer compact footprints, simple installation, and minimal infrastructure needs.

Internally rotary drum screen advantage

1. High solids capture efficiency.

2. Appropriately placed flight segments constantly conveying solids towards discharge point.

3. External spray bar and brush preventing solids accumulation on external screen surface.

4. Pivots fully adjustable and replaceable without removing screen cylinder.

5. Screen design without running seals.

6. Low energy consumption and reduced maintenance.
