    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?
    An aquaculture drum filter is a solid-liquid separation device designed to remove tiny suspended solids such as fish excrement, leftover feed, algae, and organic waste from the water. This ensures optimal water quality and clarity in fish farming systems.
    How does the automatic backwash system work?
    As the screen filters out suspended particles, it gradually becomes blocked, causing the water level inside the drum to rise. Once it reaches a set level, the automatic liquid level sensor triggers the roller motor and the backwash pump. High-pressure water sprays clean the screen, flushing the trapped waste out through the sewage drain.
    What materials are used to prevent corrosion in saltwater applications?
    Our drum filters utilize premium corrosion-resistant materials. The filter screen, critical bearings, and screws are made of SS316L stainless steel, while the tank structure is constructed from high-quality, non-toxic, corrosion-resistant engineering plastics or SS304 stainless steel, making them ideal for seawater and freshwater environments.
    Can the drum filter capacity and dimensions be customized?
    Yes. We offer fully customizable solutions to match your specific system requirements. We can design and manufacture filters of various capacities, dimensions, and inlet/outlet configurations based on your specific aquaculture setup.
    Why is a drum filter preferred over traditional sand filters?
    Unlike traditional sand filters that require high water pressure and manual backwashing, drum filters run continuously, consume less energy, do not clog easily, and automatically discharge solids from the system without interrupting the filtration process.
    What are the main applications of these drum filters?
    They are widely used in factory indoor recirculating aquaculture systems (RAS), high-density fish farms, aquaculture nurseries, ornamental fish ponds, seafood temporary holding systems, and aquarium water treatment projects.
