Wastewater Aeration Blowers

The appropriate blower or fan type depends on the process duty and installation. FRP axial fans and FRP centrifugal fans are listed for wastewater treatment plants, while centrifugal, axial, direct-drive, belt-drive and in-line or roof-mounted arrangements support different system layouts. Material selection should account for corrosive gases, temperature, airflow, static pressure and the need for spark-resistant construction.

Aerators introduce or move air within wastewater treatment processes to support biological treatment and process air requirements. The related ventilation equipment also helps manage gases and corrosive atmospheres around treatment areas. Fan selection should be based on the system design, airflow and pressure requirements, gas chemistry, mounting arrangement and any required spark-resistant or explosion-proof options.

Yes. The product range includes FRP fans and thermoplastic options using materials such as PVC, polypropylene and spark-resistant PPs-EL. These materials are intended for corrosive gas streams and chemical environments. FRP models include corrosion-resistant resin construction, while polypropylene resists acid and caustic attack through the material wall rather than relying only on a surface coating.

Axial fans move air along the fan shaft and are available for wastewater treatment applications where the system layout and airflow duty suit that arrangement. Centrifugal fans redirect air through the impeller and are also listed for wastewater treatment plants. The final choice depends on airflow, static pressure, duct configuration, mounting requirements, gas chemistry and available space.

Selected products include spark-resistant or sparkless options. Thermoplastic models can be supplied in spark-resistant PPs-EL, while FRP products can use graphite impregnation for static dissipation. Explosion-proof motor options are also listed for applicable products. The required construction and motor arrangement should be reviewed against the facility hazard assessment and system specification.

Begin with the required airflow and static pressure, then evaluate the gas chemistry, operating temperature, installation position and available electrical arrangement. Consider axial or centrifugal construction, direct-drive or belt-drive operation, in-line or roof mounting, sound requirements and spark-resistant options. IPF Colasit can help review these requirements and identify a suitable plastic or FRP configuration.
