Tube Diffuser Aeration System for Sewage Water Treatment

Tube Diffuser Aeration System for Sewage Water Treatment

Hebei Huayu Environmental Engineering Co., Ltd supplies tube diffuser aeration systems specifically designed to meet the rigorous demands of sewage‑water treatment plants. These systems deliver consistent oxygen transfer, mixing, and scouring to support activated‑sludge processes and reduce energy consumption.

System Components
A complete tube diffuser system includes a central blower station, stainless‑steel aerodynamic headers, flexible microbubble tubes, and stainless‑steel support frames. Air‑flow manifolds incorporate flow regulators to fine‑tune air distribution across diffuser trains. Isolation valves enable zone control for process optimization or maintenance.

Aeration Dynamics
Microbubble tubes create fine bubble curtains that rise evenly along the tube length, promoting vertical mixing and avoiding dead zones. Typical bubble diameters are under 1.5 mm, allowing for slow ascension and extended residence time. This design enhances oxygen utilization and reduces specific energy demand, measured as kWh per kg of O₂ transferred.

Installation and Alignment
Diffuser tubes are fixed to grid systems with adjustable brackets, allowing for precise submergence depth. Flexible airline hoses compensate for thermal expansion and minor settling of tank floors. A modular approach permits phased installation and easy retrofitting of existing tanks.

Cleaning and Maintenance
Automatic air‑scouring sequences can be programmed via PLC to periodically increase blower output, dislodging solids from the membrane surface. Manual soaking is also an option during scheduled maintenance outages. Hebei Huayu offers BRH (back‑rush hydration) kits to restore membrane flexibility after prolonged idle periods.

Operational Benefits
This tube diffuser aeration system supports both carbonaceous BOD removal and nitrification, offering steady dissolved‑oxygen profiles across the basin. Its scalable design—from small community plants to large municipal works—enables custom configurations to achieve effluent standards.
