The application of microporous aeration discs in aquaculture oxygenation is affected by various factors, so a fixed value cannot be given for their service area. However, based on the information published by Baidu Baike and empirical data from actual engineering applications, the following reference ranges can be provided:
Generally speaking, the service area of microporous aeration discs is usually between 0.25 and 0.55 square meters per disc, and there are also data indicating that their service area ranges from 0.35 to 0.75 square meters per disc. These differences may be due to different models, specifications, and actual usage conditions (such as water quality, air flow rate, etc.).
In practical applications, in order to determine the specific service area of the microporous aeration disc, the following factors need to be considered:
1. Model and specifications: Micro porous aeration discs of different models and specifications have different service areas. Generally speaking, larger models of aeration discs have a relatively larger service area.
2. Water quality conditions: The types and concentrations of pollutants in aquaculture water can affect the efficiency of oxygen transfer, thereby affecting the service area of microporous aeration discs. For example, high concentrations of substances or other pollutants may reduce the solubility of oxygen, thereby reducing the service area.
3. Airflow rate: The size of the airflow directly affects the quantity and speed of bubbles released from the microporous aeration disc. Appropriate airflow can ensure the operation of the aeration disc, thereby expanding its service area.
In addition, the performance parameters of the microporous aeration disc, such as the average pore size of the aeration membrane during operation, total oxygen transfer coefficient, oxygen utilization rate, oxygenation capacity, etc., also affect its service area. Therefore, when selecting and using microporous aeration discs, it is necessary to comprehensively consider these factors to ensure that they can meet the oxygenation needs of aquaculture water bodies.
Overall, the service area of microporous aeration discs is not a fixed value, but is influenced by various factors. In practical applications, it is recommended to determine the number and model of microporous aeration discs based on the specific conditions of the aquaculture water body (such as area, water quality, etc.) and the required oxygenation amount.
