Self-Cleaning Drum Microfilter – Food Grade Fine Debris Removal Equipment with Backwashing System
Product Description
The rotary drum microfilter is a high-efficiency, high-precision solid-liquid separation system designed to effectively remove fine visible impurities from wastewater. Built to food-grade standards, it incorporates advanced backwashing and self-cleaning mechanisms for continuous and reliable operation.
Working Principle
Wastewater enters the equipment, where solids are intercepted by the rotating hollow drum. As the drum rotates slowly, the retained debris is lifted to the highest point. Under the combined action of gravity and the backwashing system, the solids are dislodged, collected in an integrated tank, and discharged from the system. The filtered effluent passes through the drum screen and proceeds to subsequent treatment stages.
Product Advantages
Powerful filtration performance for fine debris removal
Replaceable filter elements for flexible maintenance
Integrated self-cleaning and backwashing system
Fully automatic operation with minimal manual intervention
Compact and space-saving design
