Hebei Huayu Environmental Engineering Co., Ltd’s fine bubble aerators are engineered to deliver high‑efficiency oxygen transfer and mixing in water and wastewater treatment applications. By producing micro‑to‑fine bubbles with diameters under 2 mm, these aerators enhance biological activity and chemical reaction rates.
Design Features
Each fine bubble aerator consists of a precision‑fabricated manifold, flexible microbubble tubing or flat membrane modules, and modular support hardware. Membrane materials—such as EPDM, silicone, or fluoropolymer—are selected based on feed‑water pH, temperature, and chemical exposures. Aerator assemblies are rated for continuous operation at up to 0.35 MPa.
Performance and Efficiency
Fine bubble aerators achieve oxygen‑transfer efficiencies (α∙OTR) of 1.8–3.5 kg O₂/kWh in clean‑water trials, reducing blower energy use by up to 25% compared to coarse‑bubble systems. Their low head loss and high surface‑area coverage ensure even dissolved‑oxygen distribution and robust mixing.
Installation and Scalability
Aerator units can be suspended via overhead rails or mounted on modular guide‑rail systems for ease of removal. Airline connections feature quick‑disconnect couplings and in‑line silencers. The modular design allows straightforward scaling of capacity by adding additional aerator lines.
Maintenance and Lifecycle
Routine maintenance includes low‑pressure reverse‑air scour and periodic membrane soaking in mild cleaning solutions to remove biofilm and mineral scale. Membrane replacement is tool‑free and can be completed within minutes. Hebei Huayu provides detailed maintenance schedules and replacement‑part kits to support long service life.
Applications
Fine bubble aerators support activated‑sludge tanks, membrane bioreactors (MBRs), aerated lagoons, and contact oxidation processes. Their efficient oxygen delivery promotes nitrification, denitrification, and overall treatment stability, making them a preferred option for modern water and wastewater facilities.
