Energy-Saving Tubular Aeration Pipes Reduce Energy Consumption and Improve Treatment Efficiency

Product Description

Large-scale aeration and oxygenation of municipal sewage using microporous aeration pipes

1. Product Definition
The microporous aeration tube is a long, tubular, high-efficiency microbubble oxygenation device. It has a hollow support pipe wrapped with an elastic microporous rubber membrane. Compressed air is released through the pipe wall in all directions (360°) as fine bubbles ranging from 0.2–3mm, performing both oxygenation and bottom stirring in the tank. It's widely used in municipal sewage, industrial biochemical tanks, oxidation ditches, and integrated equipment. There are two main types: fixed pipe type and liftable pipe type.

Special micro-bubble aeration pipe for wastewater biochemical treatment

2. Performance Indicators
Standard air flow per meter: 4–8 m³/h·m; best flow for a single 1m pipe is 5–7 m³/h
Effective service area: 0.8–1.5 /m; paired 2m pipes cover 1.5–3 
Bubble diameter: 0.2–3 mm
Oxygen transfer efficiency (OTE): 25%–35% (better than traditional disc type, with stronger mixing)
Oxygenation power efficiency: 6.5–7.8 kgO/kWh, significantly energy-saving
Aeration resistance loss: 2200–3000 Pa (higher than disc aerators, blower pressure needs to match)
Number of micropores: about 60,000–80,000 self-closing micropores per meter
Recommended installation height from ground: 150–250mm
Maximum applicable water depth: ≤6m

After Sales Service

360° full-area aeration, no dead corners with sludge buildup
Disc aerators only release air upwards, causing sludge to accumulate at the bottom; tube aerators provide multi-directional upward aeration, continuously disturbing bottom sludge, mixing more effectively, ideal for plug-flow bioreactors and oxidation ditches.
Even air distribution, large coverage per tube
For the same tank volume, fewer aeration tubes are needed than disc aerators, branch connections are reduced by 30%, fewer leakage points, and lower piping costs.
Self-cleaning better than disc type
When inflated, tubular membranes expand completely; the membranes repeatedly stretch and contract during startup and shutdown, shaking off surface sludge flocs and reducing the chance of large-scale membrane blockage.
Flexible installation, fits irregular tanks
Long-strip structures can be arranged along the tank length; square, rectangular, or irregular small integrated units are all compatible.
Upgraded versions allow maintenance without draining
No need to empty the tank; cleaning or replacing can be done without stopping operation, greatly reducing downtime and maintenance costs.
Corrosion-resistant, lightweight
Plastic frame and rubber membrane, no rust issues, long-term stable operation underwater.

FAQ

Pipeline Pre-Treatment: Before installing the main air pipe and branch pipes, use high-pressure air to blow off welding slag and dust—hard particles can tear the membrane pipe. 

Pipeline Flow Rate: Main pipes 10–15 m/s, branch pipes ≤5 m/s; install condensate drains at low points.

Spacing Layout: Aeration pipes should be laid parallel with a center-to-center distance of 500–800 mm, covering the entire bottom of the tank without leaving gaps.

Height Control: Keep all aeration pipes at the same height, with a maximum deviation of ±10 mm, otherwise aeration will be uneven in some areas.

Air Tightness Test: Check for leaks under low pressure, and only fill with water for commissioning once there are none.

Deep Water Reinforcement: In areas where the water depth is over 5 m or stirring is strong, add saddle supports to reduce pipe movement.
