The required air volume for each aerator depends mainly on the specifications, materials, and dissolved oxygen requirements of the water body. The total demand is obtained by calculating the sum of the required air volume for all aerators. The following is a possible calculation method and steps:
1、 Determine the required air volume for each oxygenation disc
1. Checking the specifications of the aerator: Firstly, it is necessary to consult the specification sheet or technical information of the selected aerator to understand the oxygen flow rate or air volume of each aerator under standard conditions. This is usually related to the size, design, and manufacturing materials of the oxygenation disc.
2. Considering the dissolved oxygen demand of the water body: Secondly, the actual air volume of each oxygenation tray needs to be determined based on the dissolved oxygen demand of the aquaculture water body. This is usually related to factors such as breeding species, breeding density, water temperature, and water quality conditions. This information can be obtained through water quality monitoring equipment or water quality analysis reports.
3. Calculate the air volume of a single aerator: Taking into account the above factors, the required air volume for each aerator in practical applications can be calculated. This usually requires weighing and calculating multiple factors to ensure that the oxygenation effect is achieved.
2、 Calculate the total air volume demand
1. Determine the number of oxygenation disks: Firstly, it is necessary to determine the total number of oxygenation disks required. This is usually determined based on factors such as aquaculture area, water depth, and aquaculture density.
2. Calculate total air volume: Then, add up the required air volume for each aerator disk to obtain the total air volume demand. This can be accomplished through simple mathematical calculations, multiplying the air volume of a single aerator by the total number of aerators.
3、 Precautions
1. Consider margin: To ensure the stability and reliability of the system, it is recommended to consider margin when calculating the total air volume demand. This means that a Roots blower model slightly larger than the calculated value can be selected to cope with possible future expansion or increased demand.
2. Consultant: Due to the complexity and diversity of aquaculture environments, it is recommended to consult aquaculture equipment suppliers or technicians before calculating air volume requirements. They can provide more accurate advice and guidance based on the actual situation.
4、 Example Description
Assuming that the oxygen flow rate of each aerator under standard conditions is X cubic meters per hour, and based on the dissolved oxygen demand of the aquaculture water, the required air volume for each aerator in practical applications is Y cubic meters per hour (Y may be greater or less than X, depending on various factors). If there are 60 aerators, the total air demand is 60Y cubic meters per hour.
Please note that the above is one possible calculation method and steps, which may need to be adjusted and modified according to specific circumstances in practical applications.
