Essential for aquaculture in a 35 acre fish pond: tips for using aerators and Roots blowers
For aquaculture in a 35 acre fish pond, the configuration of aerators and Roots blowers needs to consider multiple factors, including breeding species, breeding density, water quality conditions, and the specific needs of the breeders. Here is a configuration suggestion based on general situations:
1、 Oxygenation disk configuration
1. Installation method
You can choose between disc installation method or strip installation method.
Disc installation method: Use 46mm diameter steel bars to bend into a disc frame, and fix the aeration tube on the disc frame. The total length of the disc frame is recommended to be 1520 meters, with 34 aeration discs installed per acre. The disc frame needs to be fixed at the bottom of the pool, 1015 centimeters away from the bottom of the pool.
Strip installation method: The total length of the aeration pipe is about 60 meters, the pipe spacing is about 10 meters, the height difference is not more than 10 centimeters, and it is fixed at the bottom of the pool, 10-15 centimeters away from the bottom of the pool.
2. Quantity configuration
Based on a breeding area of 35 acres, if the disc installation method is chosen, approximately 105-140 aeration discs need to be configured.
If the strip installation method is chosen, the total length and quantity of aeration tubes need to be determined based on the specific pond layout and aquaculture density, but overall, sufficient aeration area and effectiveness should be ensured.
2、 Roots blower configuration
1. Selection reference
Roots blower diameter: Choose the appropriate Roots blower diameter based on the aquaculture area and water depth. For example, for a 35 acre fish pond, larger diameter Roots blowers such as 80mm or 100mm models can be selected.
Service water surface area: The service water surface area of Roots blower should be greater than or equal to the actual aquaculture area to ensure sufficient oxygenation effect.
Power and flow rate: Select appropriate power and flow rate based on breeding density and oxygen demand. Generally speaking, the higher the power and flow rate, the better the oxygenation effect.
2. Specific configuration
For a 35 acre fish pond, a Roots blower with a power of 5.5KW or 7.5KW and a flow rate of 240m3/h or 320m3/h can be selected.
The length of the aeration tube should be determined based on the layout of the pond and the position of the Roots blower, but it should ensure that the gas can be evenly distributed throughout the entire aquaculture area.
3、 Precautions
1. Maintenance and upkeep: Roots blowers and aerators require regular maintenance and upkeep during use, including replacing lubricating oil, cleaning the inside of the blower and aerator disc, etc.
2. Energy consumption: The operation of Roots blowers requires the consumption of electrical energy, so it is necessary to plan the usage time and power reasonably to save energy costs.
3. Monitoring and Control: It is recommended to equip dissolved oxygen monitoring equipment and determine the time and period for starting up and increasing oxygen based on the pattern of dissolved oxygen changes in the water body.
In summary, for aquaculture in a 35 acre fish pond, the configuration of aerators and Roots blowers should be selected and adjusted according to the actual situation. In the selection process, factors such as breeding species, breeding density, water quality conditions, and the specific needs of breeders should be fully considered to ensure the effectiveness of oxygenation and economic benefits.
