How to design a traditional filtration tank for a fish pond

The design of a traditional fish pond filtration tank typically includes several key steps and elements:

1. Determine the location and size of the filtration basin:
- The filter should be located at one end or corner of the fishpond to allow for easy channeling of water flow.
- Determining the size of the filtration tank is usually based on the size of the tank and the number of fish.

2. Planning of the structure of the filtration basin:
- Filtration ponds typically consist of multiple compartments, including a sedimentation compartment, a physical filtration compartment, a biochemical filtration compartment, and a clear water compartment.

3. Design of sedimentation bins:
- This is the first compartment of the filter tank and is used to settle larger solid particles.
- They are usually designed to be larger to slow down the flow of water and allow heavy materials to settle.

4. Design of physical filtration bins:
- Immediately following the sedimentation bin, it is used to remove smaller particles and suspended matter.
- Use filter materials such as sponges, filter wool or other porous materials.

5. Design of biochemical filtration bins:
- Used to cultivate beneficial bacteria to break down ammonia and nitrite in fish feces.
- Materials used include ceramic rings, biospheres, and volcanic rocks that provide a large surface area for bacteria to attach to.

6. Design of clean water silos:
- A final compartment for storing filtered water, which is then pumped back to the fish pond.
- Can be designed with shallower bins for easier cleaning and maintenance.

7. Water flow design:
- Ensure that water flows evenly through each chamber to avoid the formation of stagnant areas.
- Use pumps and piping systems to control the direction and speed of water flow.

8. Pipelines and pumps:
- Select a suitable pump to ensure that its flow rate and head are appropriate for the needs of the filter tank.
- Design of the piping system, including inlet pipes, outlet pipes and pipes connecting the various bins.

9. Maintenance and cleaning:
- Design filtration basins that are easy to clean and maintain so that the filter material can be replaced and the sediment cleaned on a regular basis.

10. Aesthetics and concealment:
- If possible, design the filtration pond to blend in with its surroundings or hide it in the landscape.

11. Security considerations:
- Ensure that the filter tank is structurally sound to avoid collapse or damage.
- Ensure the safety of pumps and electrical equipment to avoid the risk of electrocution.

12. Budget and selection of materials:
- Choose the right material according to your budget, such as plastic, concrete or stone.

13. Environmental impact:
- Consider the impact of the filtration pond on the surrounding environment, such as noise and visual impacts.

14. Backup systems:
- Consider designing a backup filtration system in case the primary filtration system fails.

15. Automation and monitoring:
- If possible, consider automated systems to monitor the operational status of the filtration basin, such as an automated backwash system.

When designing a traditional fish pond filtration tank, the specific needs of the pond and environmental conditions should be taken into account to ensure the effectiveness and sustainability of the filtration system.
