Drum filter(s)

The Purusaqua drum filters are designed to be used in aquaculture and the industry. The first Purusaqua drum filters have been in use since 2007 and have since then definitely proven their worth. Purusaqua drum filters come standard with extensive controls, flush pump and lid. Our drum filters are unique in performance and quality, which is also the reason why they are used in many countries.

A couple advantages of our filters:

  • Casing fully made out of 12mm thick polypropylene (PP)
  • Built very robustly, the most heavily loaded weld seam has been welded with an extruder&nbsp
  • Compactly built
  • Available for maximum water flows ranging from 25m³/hr up to 350m³/hr
  • Gear-driven, no axle connections under water that can start to leak
  • 24VDC propulsion (also suitable for swimming ponds) (25, 50 and 100m³/hr model)
  • It’s possible to install a UVC lamp
  • Measuring of the water level through pressure
  • There are no floats that can get stuck
  • Purge levels can be set per mm
  • Low water alarm can be set per mm (deactivates the circulation pump and optionally the UVC when the water level gets too low)
  • Rotation speed of the drum can be infinitely adjustable
  • Flush time infinitely adjustable
  • Overflow protection can be set, deactivates the propulsion engine when the load is too big
  • Controls automatically shut down the (optional) UV when the lid is opened
  • Flush process is blocked when the lid is opened, this prevents risk of entrapment!
  • Equipped with an alarm output
  • Controls keep track of the intervals between the last 3 flushes

Drum Filters

Drum filters have emerged as a revolutionary component in the field of water filtration, offering efficient and reliable solutions for various applications. These filters utilize a rotating drum to remove debris and impurities from water, providing a comprehensive and low-maintenance filtration method.

How Drum Filters Work

The fundamental mechanism of drum filters involves water passing through a drum, typically made of fine mesh or perforated material. Mechanical filtration occurs, trapping particles and waste on its surface. Clean water then exits through the filter. When the mesh is clogged, the drum will rotate and a rinsing cycle will start. During the rinsing cycle the collected debris is removed from the drum, keeping the system in optimal condition.

Advantages of Drum Filters

  1. High Filtration Efficiency: Drum filters excel in removing both large and small particles from water, ensuring a thorough filtration process.
  2. Low Maintenance Requirements: Compared to traditional filtration methods, drum filters have minimal maintenance needs. The automatic cleaning mechanism reduces manual intervention, making them suitable for both residential and industrial applications.
  3. Space-Efficient Design: Drum filters are known for their compact design, making them suitable for installations where space is a constraint. Their efficiency is not compromised by their smaller footprint.
  4. Continuous Filtration: During a rinsing cycle, the normal operation of a drum filter is not interrupted. ty without interruptions.
  5. User-Friendly Operation: Many drum filters are equipped with user-friendly controls, enabling easy customization of filtration settings and monitoring of system performance.

Drum Filters for Koi Ponds

Koi enthusiasts and pond keepers recognize the importance of maintaining pristine water conditions for the health and vibrancy of their prized fish. Drum filters play a crucial role in achieving and sustaining optimal water quality in koi ponds.

Key Considerations for Koi Ponds

  1. Particle Size Removal: Koi ponds often accumulate fine particles and uneaten food. Drum filters with a fine mesh or perforated plate are effective in capturing these small particles, preventing water cloudiness and maintaining water clarity.
  2. Biosecurity and Disease Prevention: Koi are susceptible to diseases, and maintaining a clean pond environment is paramount. Drum filters aid in removing organic material, a feeding round for harmful bacteria and pathogens.
  3. Efficient Mechanical Filtration: The automatic cleaning mechanism of drum filters ensures that mechanical filtration is consistently efficient, reducing the risk of clogs and blockages that can occur with other filtration methods.
  4. Integration with Existing Pond Systems: Drum filters can be seamlessly integrated into existing pond filtration systems, complementing other filtration components such as biofilters and UV sterilizers.
  5. Adjustable Filtration Levels: Koi pond owners can adjust the filtration levels based on specific requirements, accommodating variations in fish load, feeding habits, and environmental factors.

Pond Drum Filter

Pond drum filters cater to a broad spectrum of water bodies, from backyard ponds to large-scale aquatic facilities. Their versatility and effectiveness make them a popular choice for maintaining water clarity and quality in various pond environments.

Applications of Pond Drum Filters

  1. Residential Ponds: Homeowners with decorative ponds or water features benefit from the compact size and efficiency of pond drum filters. These filters enhance the aesthetics of the pond by keeping the water clear and free from debris.
  2. Commercial Aquaculture: Pond drum filters find extensive use in commercial aquaculture settings, where maintaining optimal water quality is crucial for the health and growth of aquatic organisms. They contribute to the efficiency of fish farms and aquaculture facilities.
  3. Municipal Water Features: Public parks and recreational areas with ponds or water features utilize drum filters to ensure that the water remains clean and visually appealing. These filters contribute to the overall maintenance of public spaces.
  4. Zoological Institutions: Zoos and aquariums employ pond drum filters in their aquatic exhibits to provide a healthy and visually pleasing environment for aquatic life. The continuous filtration ensures that the water remains pristine for both the animals and visitors.
  5. Swimming ponds: Removing organic material in swimming ponds is a necessity for pristine water quality. Drum filters are the best choice for this task

Installation and Maintenance of Pond Drum Filters

Proper installation and regular maintenance are crucial for the optimal performance of pond drum filters.

  1. Installation Considerations: Always choose a drum filter which is large enough for the application. It is better to have a drum filter that is oversized then a undersized filter
  2. Routine Cleaning and Inspection: Regular cleaning of the drum is necessary to prevent clogs and ensure consistent performance.
  3. Monitoring System Performance: Pond owners should monitor the performance of the drum filter regularly. Many modern drum filters come equipped with monitoring systems indicating rinse intervals.

FAQ

Why should I choose a drum filter for my pond?

A drum filter has a high filtration efficiency, low maintenance requirements, and the ability to remove both large and small particles.

What maintenance is required for a pond drum filter, and how often should it be cleaned?

Maintenance is a crucial aspect of any filtration system. A drum filter usually should be checked once a week. During this check it might be necessary to clean the waste chute.

In some cases it might be necessary to degrease the mesh once in a while. The interval depends on the waste load and the amount of fats and proteins.
