Preparation Before Installing Diffuser Discs
Installation Steps for Diffuser Discs
1.Install Support Brackets
First, install brackets or hangers inside the aeration tank based on design specifications. These brackets will be used to secure the diffuser discs. The brackets should be sturdy and able to withstand the pressure from the diffuser discs and airflow.
2.Connect Air Piping
Connect the diffuser discs to the air source using pipes. Ensure that the pipe connections are airtight to prevent gas leaks. During installation, avoid twisting or bending the pipes to maintain stable airflow.
3.Install Diffuser Discs
Mount the diffuser discs onto the brackets, ensuring that each diffuser disc is level. Check that the surface of the disc is flat to ensure uniform bubble release.
4.Test System Operation
After installation, conduct a system test to ensure uniform gas distribution, bubble size according to design specifications, and that airflow and pressure are within normal ranges.
1.Confirm Design Parameters
Ensure that the chosen diffuser disc model matches the design requirements of the water treatment system. This includes design flow rate, oxygen transfer efficiency, bubble size, etc., all of which should meet the actual needs of the wastewater treatment plant.
2.Cleaning and Inspection
Before installation, thoroughly clean the diffuser discs and related equipment to avoid any debris or contaminants affecting system performance. Additionally, check for any damage or defects in the diffuser discs to ensure all parts are intact.
3.Proper Piping Layout
The installation position of the diffuser discs and piping layout must ensure that air is evenly distributed to each diffuser disc, avoiding uneven air distribution.
Maintenance and Cleaning of Diffuser Discs
1.Regular Cleaning
The membranes of diffuser discs may become clogged with debris, sludge, or biofilm, leading to uneven bubble release. Regular cleaning is necessary, especially in environments with poor water quality, where cleaning frequency may need to be higher.
2.Check Membranes and Seals
Periodically check the membranes and seals of the diffuser discs to ensure they are not damaged or worn. Damaged parts should be replaced promptly to prevent reducing the efficiency of the system.
3.Check Airflow and Pressure
Regularly check the airflow and air pressure to ensure stable system operation. If a decrease in airflow or unstable pressure is detected, this may indicate membrane clogging or air pipe leaks, which need to be addressed immediately.
Important Notes
1.Diffuser discs should be installed in appropriate locations to avoid performance degradation due to environmental factors such as temperature changes and chemical corrosion.
2.When cleaning diffuser discs, avoid using harsh cleaners or mechanical cleaning methods that may damage the membrane or other parts.
3.For large-scale wastewater treatment systems, it is recommended to establish dedicated maintenance cycles and personnel to ensure that the diffuser discs are properly maintained.
