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
