China Drum Filter Suppliers - High-Quality Rotary Drum Micro Filtration Factory for Solid-Liquid Separation
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)
What is the primary function of an aquaculture drum filter?
The drum filter acts as a solid-liquid separation equipment. It filters out tiny suspended substances in the water, such as fish excrement, bait, pulp fiber, sand, and plankton (like algae and daphnia).
How does the automatic backwash system work?
During filtration, suspended particles gradually block the filter screen. When the screen becomes blocked, the liquid level automatic control component detects the change and automatically starts the backwash water pump and roller reducer to clean the screen.
What materials are used to construct the Submersible Drum Filter?
For maximum durability and corrosion resistance, the screen, bearings, and screws of the submersible drum filter are made of SS316L stainless steel, while the other components are constructed from SS304.
Can the drum filter sizes be customized according to specific requirements?
Yes. While standard sizes are available, the drum filters can be customized to various sizes to match the specific space and filtration requirements of your aquaculture system.
Why is a drum filter considered more energy-efficient than a sand tank?
Unlike traditional sand tanks that require high water pressure to operate, the drum filter operates continuously with lower energy demand, is non-blocking, and efficiently removes solid waste without constant high-pressure pumping.
Where are these drum filters commonly applied?
They are widely used in factory indoor high-density aquaculture farms, nursery grounds, ornamental fish bases, temporary seafood maintenance/transportation, and various aquarium or fish pond projects.
