Key Advantages

1. High oxygenation efficiency, lower energy consumption
The membrane's tiny pores release bubbles smaller than 1mm, greatly increasing the gas-liquid contact area, and under standard conditions, oxygen utilization can reach 30%; 
With the same aeration effect, the blower uses less energy, saving electricity and reducing costs over the long term.

2. Clog-proof and backflow-resistant, with a long maintenance cycle
It has a built-in one-way check structure. After shutdown, the diaphragm automatically tightens to close the micro-holes, preventing sludge from flowing back into the aeration branch. High-quality EPDM rubber is resistant to scaling and sticking to sludge, greatly reducing the frequency of disassembly and cleaning.
3. Corrosion-resistant and long-lasting
The main chassis is made of anti-aging ABS engineering plastic, and the diaphragm is made of acid- and alkali-resistant EPDM rubber/food-grade silicone, suitable for various industrial wastewater with different pH levels. Under normal sewage conditions, it can be used steadily for 3-5 years.

Simple Technical Specs Summary

 Flexible installation and strong adaptability  
Comes with standard UPVC pipe clamp fittings, which can be fixed directly on the aeration branch at the bottom of the tank, so layout isn't limited by the tank shape; three sizes available to match different tank volumes and wastewater loads, suitable for both small tanks and large biochemical tanks.  
 Low operational noise and high stability  
Microbubbles provide gentle air release, no loud bubble bursts; pressure stable, can be submerged up to 8 meters, and even under high water levels and large aeration volumes, the membranes won't tear or leak.   Good suitability for intermittent aeration  
Designed for intermittently operated wastewater treatment tanks, repeated start-stop cycles won't cause backflow blockages, no extra anti-backflow fittings needed, simplifying the design of the whole aeration system.

Disc micro-porous aerator

1. Basic Product Introduction
The disc-type microporous aerator is a specialized oxygenation device for biochemical tanks in wastewater treatment, and it is also a mainstream aeration accessory from Yangzhou Deyuan Environment. It consists of four parts: EPDM rubber/silicone microporous diaphragm, ABS plastic support base, one-way check valve, and connecting clip. Common sizes are Φ215mm, Φ260mm, and Φ300mm.
Working principle: When air is supplied by the blower, the rubber diaphragm's micropores expand to release tiny bubbles. When the machine stops and pressure is released, the diaphragm's micropores automatically close to prevent sludge and wastewater from backflowing and clogging the pipes.
Suitable scenarios: municipal domestic sewage, chemical, food, textile wastewater, and aquaculture tail water. It can be used for continuous aeration or intermittent aeration processes.

Daily Maintenance and Cleaning Plan
Daily Inspection (Every Day)
Check if the bubbles are continuous and uniform; if the fan pressure rises by more than 15%, it indicates micropore blockage; no bubbles in certain areas = membrane damage or branch blockage.
Physical Blowing (Once every 1–2 months)
Run low airflow in reverse for 3–5 minutes, letting the membrane tubes shake off sludge; use a low-pressure water jet to wash the pipe walls in the tank.
Chemical Acid Cleaning (For inorganic calcium and magnesium scale, every 6 months–1 year)
Drain the tank, soak in 5% dilute hydrochloric acid for 30–60 minutes to dissolve inorganic salt crystals, rinse with clean water, then restart operation.
Replacement Standard
If membrane tubes have large-scale cracks, lose elasticity, or resistance is still high after acid cleaning and blowing, replace the entire membrane tube, while the support frame can be reused.

FAQ

How does the aerator prevent clogging?
It features a built-in one-way check valve that automatically closes micro-holes when pressure is released, preventing sludge backflow.
What is the expected service life?
Under normal sewage conditions, the aerator can operate steadily for 3 to 5 years.
What materials are used for the membrane?
The membrane is made of acid- and alkali-resistant EPDM rubber or food-grade silicone.
Can the product be customized?
Yes, we offer OEM, ODM, and full customization options based on samples or designs.
How is the maintenance performed?
Maintenance includes daily inspection, physical blowing every 1-2 months, and chemical acid cleaning every 6-12 months.
What is the oxygen utilization rate?
Under standard conditions, oxygen utilization can reach 30% due to tiny bubbles increasing gas-liquid contact.
What is the minimum order quantity?
The minimum order quantity is 1 set.
