Why is my disc aeration diffuser losing efficiency?

- Loss of efficiency can be caused by clogged air holes, deterioration of the diffuser material or problems with the air supply system. Regular inspections and maintenance are necessary.
A disc aeration diffuser losing efficiency can be due to several factors. Here are some common reasons:
1. Fouling and Clogging: Over time, the pores of the diffuser membrane can become clogged with biological growth, minerals, or other debris from the water. This clogging reduces the diffuser's ability to release fine bubbles, thus decreasing oxygen transfer efficiency.
2. Aging of Membrane: The material of the diffuser membrane can deteriorate or become less elastic with age and continuous use. This can lead to larger bubbles, which are less efficient for oxygen transfer compared to finer bubbles.
3. Air Supply Issues: If the air supply to the diffuser is compromised, whether by leaks in the system, inadequate air pressure, or flow rate, the efficiency of the diffuser will decrease. Ensuring that the air supply system is operating correctly is crucial for maintaining diffuser efficiency.
4. Improper Cleaning: Improper or infrequent cleaning can lead to a build-up of materials on the diffuser surface, reducing its efficiency. Chemical or physical cleaning processes that are too harsh can also damage the diffuser, further reducing its effectiveness.
5. Water Quality: The quality of the water being aerated can affect diffuser efficiency. High levels of certain chemicals or minerals in the water can accelerate the fouling process or even damage the diffuser.
6. Inadequate Maintenance: Regular maintenance is critical to ensure the longevity and efficiency of aeration diffusers. Neglecting maintenance can lead to a variety of issues that cumulatively reduce the system's overall performance.
To diagnose the exact cause of the efficiency loss in your specific case, it would be advisable to conduct a thorough inspection of the aeration system, including the diffuser membranes, air supply equipment, and the water quality. Depending on the findings, actions such as cleaning or replacing the diffusers, repairing air supply components, or adjusting maintenance procedures may be necessary.
