CrawTec combined drum filters for CLS and ponds

Combination drum filters are an innovative solution for effective water treatment in closed-loop water supply (CLS) plants, ponds, aquaculture and other systems requiring high water quality. These devices combine mechanical and biological filtration to provide an integrated approach to maintaining a clean and healthy aquatic environment.

Advantages of Combination Drum Filters:

Dual filtration: The combination of mechanical cleaning with a drum filter and biological filtration ensures the removal of both solids and dissolved organic matter.

Process Automation: The drum filter automatically removes mechanical contaminants, reducing the need for frequent maintenance and saving operator time.

Compact: Combining two types of filtration in one unit saves space and simplifies system installation.

Energy efficiency: Modern models are designed to minimise energy consumption while maintaining high performance.

Application of combined drum filters:

• Closed Water Supply Plants (CWS): Maintaining optimum conditions for the growth of fish and other aquatic organisms.
• Ponds and ornamental ponds: Ensuring water clarity and preventing the development of undesirable microorganisms.
• Aquaculture: Creating a healthy environment for fish, shrimp and other hydrobionts.
• Fish farms: Improving water quality to enhance fish productivity and health.

How to choose a combination drum filter:

The following factors should be considered when choosing the right model:

1. Capacity: The filter should match the volume of water in the system and provide the required filtration rate.
2. Drum filter mesh size: The optimum mesh size depends on the type of organisms to be cultured and the degree of water contamination.
3. Biofilter type: Different models offer different solutions for biological filtration, such as moving bed bio-loading or stationary bio-materials.
4. Materials and construction: Quality materials ensure durability and resistance to corrosion, while the clever design makes maintenance easy.

Installation and maintenance:

Combination drum filters are generally easy to install and require minimal maintenance. The automatic drum flushing system reduces the need for manual cleaning, and the biofilter requires periodic monitoring and, if necessary, flushing or replacement of the biomaterial.

Investing in a combination drum filter is an effective way to ensure high quality water in your system. By combining mechanical and biological filtration in a single unit, you can maintain optimal conditions for aquatic organisms to grow, reducing maintenance costs and increasing the efficiency of your entire system. When choosing the right model, consider the specifics of your installation and water quality requirements to ensure long-term, consistent performance of your filtration system.
