Hebei Huayu Environmental Engineering Co., Ltd offers a range of air fine bubble tube aerators designed for efficient oxygen transfer in municipal and industrial wastewater treatment applications. These tube aerators generate micro‑to‑fine bubbles (typically 1–3 mm in diameter), which rise slowly through the liquid column, maximizing contact time and oxygen dissolution.
Design and Construction
Each tube aerator consists of a durable header manifold—constructed from corrosion‑resistant stainless steel (304L or 316L) or carbon‑steel with epoxy lining—connected to a series of flexible microbubble membranes. The membranes are available in materials such as EPDM or silicone, selected for mechanical resilience and chemical compatibility. Precision‑machined end caps and gasketed joints ensure leak‑free operation at pressures up to 0.3 MPa.
Aeration Performance
Fine bubble tube aerators achieve oxygen transfer efficiencies (α‑values) of 0.5–0.7 under standard test conditions (20 °C, clean water), reducing energy consumption compared to coarse‑bubble systems. Adjustable air‑flow distributors allow operators to balance oxygen delivery across multiple tubes, compensating for varying tank depths and hydraulic loads.
Installation and Operation
The tube assemblies can be suspended from overhead rails or mounted on guide rails for easy removal during maintenance. Airline piping connects to blowers via flexible hoses or stainless‑steel rigid piping, with inline butterfly valves and differential‑pressure gauges to monitor distribution and detect blockages.
Maintenance and Cleaning
Periodic back‑flushing with clean water or mild cleaning agents removes accumulated biomass and mineral deposits from the membrane surface. Individual tube cartridges can be replaced in minutes without disturbing adjacent units. Hebei Huayu provides detailed maintenance manuals and spare‑parts kits to minimize downtime.
Applications
These tube aerators are compatible with activated‑sludge basins, sequencing‑batch reactors (SBRs), oxidation ditches, and aerated lagoons. Their fine‑bubble pattern promotes uniform mixing and prevents dead zones, supporting biological nutrient removal and improving effluent quality.
