High Efficiency China Microporous Ceramic Plate Fine Bubble Diffuser Suppliers and Factory for Water Treatment Solutions
Product Details
This product utilizes an increased gas-liquid contact area to enhance the total amount of gas dissolved in the liquid. Gas passes through the extremely small pores of a nano-scale microporous ceramic aeration plate, dispersing into tiny mist-like microbubbles with diameters between 0.05 and 0.5 mm in the liquid. As the microbubbles rise, oxygen dissolves into the water, achieving efficient oxygenation. Dissolution efficiency is directly proportional to the gas release depth. This product's aeration plate has a pressure resistance of up to 700 kPa and can be used in liquids less than 60 meters deep. In areas without a power supply, it can be used directly with a high-pressure oxygen tank without requiring electricity.

High Energy Efficiency
Operates normally at a pressure of 150-200 KPA.
Debugging Procedures and Methods
1
After installing the nanoscale microporous ceramic aeration plate according to the typical installation diagram, ensure that the nanoscale microporous ceramic aeration plate is placed horizontally in the water. Re-check that all components are properly installed and undamaged.
2
Adjust the outlet pressure of the gas source (liquid oxygen cylinder) to 350 KPA. Set the outlet pressure regulating valve pressure to 150-200 KPA. (Adjust according to oxygen supply requirements)
3
Slowly open the flow meter valve. When a small amount of bubbles appear on the surface of the aeration ceramic, re-check all pipe joints for leaks. If there are no leaks, adjust the flow meter to the required flow rate.
Working Principle
This product utilizes an increased contact area between gas and liquid to enhance the total amount of gas dissolved in the liquid. The gas passes through the extremely small pores of a nano-scale microporous ceramic diffuser plate, dispersing into tiny mist-like microbubbles with diameters between 0.05 and 0.5 mm in the liquid. As the microbubbles rise, oxygen dissolves into the water, achieving efficient oxygenation. The dissolution efficiency is directly proportional to the gas release depth. This product's aeration plate has a pressure resistance of up to 700 KPA and can be used in liquids with a depth of less than 60 meters. It can be used directly with a high-pressure oxygen tank in areas without a power supply, requiring no electricity.
Routine Maintenance
Routine maintenance of the nano-scale microporous ceramic aeration plate involves regularly cleaning the surface of the ceramic plate. The specific cleaning methods are as follows:
1
Normal Cleaning: Manually use a hard nylon brush (metal brushes are not allowed) to remove clay or other dirt from the surface of the nano-scale microporous ceramic aeration plate. High-pressure water guns can also be used for rinsing. After the surface is cleaned, thoroughly dry the nano-scale microporous ceramic aeration plate before placing it in clean water. Use 1500-mesh or 2000-mesh ordinary sandpaper to polish the surface of the ceramic plate until the old surface layer is removed. Determine whether repeated cleaning is necessary based on the results, until a satisfactory result is achieved. Under normal circumstances, the above cleaning methods can solve most of the clogging problems of the nano-scale microporous ceramic aeration plate. If the cleaning effect is still unsatisfactory, consider acid cleaning.
2
Acid Cleaning: Before acid cleaning, perform normal cleaning. After normal cleaning, thoroughly dry the nano-scale microporous ceramic aeration plate. Pour 5-10% dilute hydrochloric acid into a container of appropriate size (the concentration of dilute hydrochloric acid should not exceed 10%). Immerse the nano-scale microporous ceramic aeration plate in the acid solution, ensuring that the liquid level is approximately 3mm above the surface of the ceramic plate. Soak for 12 hours. After soaking, rinse with clean water and then aerate in clean water for 15 minutes to completely blow out the acid solution from the nano-scale microporous ceramic aeration plate. Based on the cleaning results, determine whether to repeat the cleaning until a satisfactory result is achieved.
Application Fields
- Aquaculture: Industrial recirculating aquaculture systems, industrial semi-recirculating aquaculture systems, flow-through aquaculture, pond aquaculture, cage aquaculture, hatchery, temporary holding tanks, aquarium and ornamental fish farming, increasing stocking density, reducing farming costs, and emergency backup during power outages.
- Live Fish Transportation: Increasing live fish transportation density, reducing mortality rates, and lowering transportation costs.
- Live Fish Processing: Carbon dioxide anesthesia, reducing stress response of live fish in holding tanks.
- Wastewater and Sewage Treatment: High-efficiency aeration, oxygen supplementation, and pH control using carbon dioxide.
Our Advantages
- High pressure resistance, good sealing performance, and not easy to clog.
- The ceramic surface is flatter, with higher strength, no long streaks, and no cracking.
- Compared with similar specifications in the industry, it is heavier and less likely to move in the water.
- The ceramic thickness is twice that of the same industry.
- The pore size is 0.8 micrometers, and the pores are uniform. Compared with the 1.0 or 1.2 micrometer pore size in the same industry, the bubbles are smaller, the oxygen dissolution efficiency is higher, thus saving oxygen and reducing costs.
- Higher safety: The ceramic sheet is made of alumina fired at a high temperature of 350℃. The product's safety and hygiene meet ROSH standards and will not react chemically with water. Compared with aeration plates made of alloys (fired with various metals), it is safer.

The aeration plate features an ultimate pressure resistance of up to 700 kPa (0.7 MPa) and can be safely and effectively used in liquid depths of up to 60 meters.
How should I perform routine maintenance and cleaning?
For normal cleaning, manually scrub the surface with a hard nylon brush (never metal) or wash with a high-pressure water gun, then dry and sand with 1500-2000 mesh sandpaper. For severe clogs, perform normal cleaning first, dry, and then soak the plate in a 5-10% dilute hydrochloric acid solution for 12 hours before rinsing and aerating.
Why is an alumina ceramic plate safer than alloy alternatives?
The ceramic sheet is made of pure alumina fired at a high temperature of 350°C. It meets RoHS safety and hygiene standards, does not react chemically with water, and avoids the risk of releasing metal elements into the aquatic environment.
