Disc Diffuser plays a vital role in the sewage treatment process, so its maintenance and cleaning are essential to ensure the efficient operation of the system. Here are some methods and suggestions on how to maintain and clean disc aerators.
Regular inspection
1. Visual inspection: Regularly check the appearance of the aerator, especially whether the diaphragm is damaged, cracked or aging. If any abnormality is found, the diaphragm or the entire aerator should be replaced in time.
2. Air flow inspection: Check whether the air flow of the aerator is uniform. If the air flow in a local area is found to be too large, it may be due to leakage in the air distribution branch pipe or damage to the diaphragm, which needs to be repaired or replaced accordingly.
Cleaning method
1. Empty the aeration tank: First, empty the aeration tank to better carry out the cleaning work.
2. Clean with water and brush: Use clean water and a soft brush to clean the surface of the aerator to remove attached dirt and impurities.
3. High-pressure cleaning: For dirt that is difficult to remove, you can use a high-pressure water gun to clean it.
4. Disassembly and cleaning: If there is a lot of dirt on the aerator, you can consider disassembling it and cleaning it part by part.
5. Automatic cleaning device: During operation, the aerator can be cleaned regularly using an automatic cleaning device to reduce the workload of manual cleaning.
Maintenance measures
1. Select high-quality materials: When selecting a disc aerator, materials with good quality, strong corrosion resistance, and good high and low temperature resistance should be selected to extend its service life.
2. Reasonably adjust working parameters: According to the actual water volume and water quality, reasonably adjust the working pressure and aeration volume to avoid fatigue and damage of the diaphragm due to excessive use.
3. Monitor water quality: Strengthen the monitoring of the sewage treatment system, promptly detect and deal with abnormal water quality, and prevent damage to the rubber diaphragm.
4. Clean sediment regularly: Check whether there is sediment and crust on the aerator diaphragm, and clean or replace the diaphragm in time to maintain a good aeration effect.
Troubleshooting
1. Uneven air flow: If uneven aeration is found, it may be due to insufficient blower capacity or malfunctioning valves. Check and confirm that the blower is working properly and adjust the valve position.
2. Reduced dissolved oxygen level: If the dissolved oxygen level is reduced or the system resistance loss is increased, it may be due to sediment on the aerator diaphragm or aging of the diaphragm. The diaphragm should be checked and cleaned, and the diaphragm or the entire aerator should be replaced if necessary.
The above methods and measures can effectively maintain and clean the disc aerator to ensure its efficient operation in the sewage treatment process.
