Automatic Backwashing Drum Microfilter – Food Grade Fine Particle Removal System

Food-Grade Drum Microfilter with Self-Cleaning & Backwashing System

Product Overview
The rotary drum microfilter is a high-efficiency solid-liquid separation system designed for fine debris removal in food-grade applications. It effectively screens and removes visible fine impurities from wastewater while meeting stringent hygiene and safety standards.

Working Principle
Wastewater enters the unit and flows into a hollow rotating drum. Solids are retained on the drum surface and transported upward as the drum rotates. Upon reaching the highest point, debris is dislodged by gravity and a pressurized backwashing system, collected in an integrated tank, and discharged. Simultaneously, filtered effluent passes through the drum mesh and advances to subsequent treatment stages.

Key Features

• High-efficiency filtration for fine particle removal

• Replaceable filter components

• Integrated self-cleaning and backwashing mechanisms

• Fully automated operation

• Compact, space-saving design
