High-Quality Rotary Drum Filter from China Suppliers - Reliable Solid-Liquid Separation Equipment from Factory
Stainless Steel Aquaculture Drum Filter for Fish Farming System
Drum filter (also known as drum micro filtration screen) is a solid-liquid separation equipment, widely used in the first stage of raw water or sewage solid-liquid separation process in aquaculture, waterworks, urban domestic sewage, papermaking, textile, printing and dyeing, chemical industry, etc.
It is mainly composed of four parts: tank component, roller component, backwash component and liquid level automatic control component. The roller component consists of a roller frame (which can be made of metal or plastic) and a screen (stainless steel screen or nylon screen). The main function is to filter tiny suspended substances in the water (fish excrement, bait, pulp fiber, sand), Plankton such as algae and daphnia.
Box Type Drum Filter
The drum filter is mainly composed of four parts: tank component, roller component, backwash component and liquid level automatic control component. It is made of non-toxic seawater corrosion-resistant high-quality engineering plastic materials. A stainless steel filter screen is fixed on the rotatable drum, and the tiny suspended substances in the water are separated and filtered through the screen and finally achieve solid-liquid separation.
During the filtering process, small suspended particles in the water will cause the screen to be blocked. When the screen is blocked, the liquid level automatic control component works, and the backwash water pump and roller reducer automatically start working to make the screen timely cleaning to keep the equipment in good working condition.

Submersible Drum Filter
The open drum filter is mainly composed of three parts: roller component, backwash component and electric control box system.
A stainless steel filter screen is fixed on the rotatable drum, and the tiny suspended substances in the water are separated and filtered through the screen and finally achieve solid-liquid separation.
During the filtering process, small suspended particles in the water will cause the screen to be blocked. When the screen is blocked, the liquid level automatic control component works, and the backwash water pump and roller reducer automatically start working to make the screen timely cleaning to keep the equipment in good working condition.

Frequently Asked Questions (FAQ)
Q: What is the main function of an aquaculture drum filter?
A: It is a solid-liquid separation system designed to filter out tiny suspended particles such as fish waste, uneaten bait, organic matter, algae, and plankton from the water body.
Q: How does the automatic backwash system work?
A: As particles block the filter screen, the water level changes. This triggers the liquid level sensor, automatically activating the backwash pump and roller reducer to spray clean water and clear the screen.
Q: What materials are used to prevent corrosion in saltwater?
A: The critical parts, including screens, bearings, and screws, are made from high-grade SS316L stainless steel, while the body components are built from corrosion-resistant SS304 or high-quality engineering plastics.
Q: Can the drum filter run continuously without manual intervention?
A: Yes, it is designed for continuous 24/7 operation. The intelligent water level control system automatically manages the cleaning cycles, reducing maintenance and labor costs.
Q: Can the drum filters be customized for specific project requirements?
A: Absolutely. While we have standard specifications, we can customize dimensions, inlets/outlets, and capacities to match the unique design of your fish farming system or wastewater plant.
