Drum Filter for Fish Farming

Filtration Capacity:

• Flow rate: 10 m³/h to 500 m³/h (varies based on size and application).
• Suitable for small-scale to large-scale fish farming operations.

2. Mesh Size (Micron Rating):

• Common sizes: 20 µm to 200 µm.
• Smaller mesh sizes remove finer particles, suitable for systems requiring high water clarity.

3. Drum Dimensions:

• Drum diameter: 0.5 meters to 2.5 meters.
• Drum length: Depends on capacity and system design.

4. Material:

• Housing and frame: Stainless steel (e.g., SS304 or SS316) for corrosion resistance.
• Drum mesh: Stainless steel or durable synthetic materials like polyester.

5. Drive System:

• Motor type: Electric motor or hydraulic drive.
• Rotation speed: Adjustable, typically between 1–5 RPM.

6. Cleaning Mechanism:

• Automatic backwashing system using spray nozzles.
• Operates based on water level sensors or time intervals.
• Pressure range for cleaning jets: 3–6 bar.

7. Water Pressure Requirements:

• Inlet pressure: Usually between 0.5–1.5 bar.

8. Power Requirements:

• Motor power: 0.5 kW to 5 kW, depending on the drum size and system configuration.
• Voltage: 110V/220V/380V (as per regional standards).

9. Solids Handling:

• Handles high concentrations of suspended solids (e.g., fish waste and uneaten feed).
• Solid waste collection trough or hopper for easy disposal.

10. Installation:

• Orientation: Horizontal or vertical, based on system layout.
• Mounting: Free-standing or integrated into filtration systems.

11. Construction Features:

• Sealed design: Prevents water leakage and contamination.
• Corrosion-resistant coatings: Suitable for saltwater or freshwater applications.

12. Automation & Control:

• PLC-based control system for automation.
• Sensors for water level, flow rate, and system monitoring.

13. Durability:

• Designed for continuous operation in harsh environments.
• Longevity: Typically lasts 5–10 years with proper maintenance.

14. Optional Features:

• UV-resistant components for outdoor use.
• Integrated biofilter sections.
• Variable speed control for energy efficiency.
