Integral with any submerged aeration system is a pressurised supply air source to compress air for release below the water surface. The new INVENT iTURBO- Blower has been designed specifically for this application.
INVENT has designed an advanced turbo blower and implemented state of the art manufacturing techniques that allow blowers to be customised to the unique requirements of any wastewater treatment plant. The company says this ensures the energy consumption and operating range is optimized for the specific process. The result is a dedicated machine operating at peak performance tailored for every application.
The iTURBO-Blower is a radial compressor in either single or two stage configurations. The compressor is direct driven by a high-speed permanent magnet motor.
With over ten years of development and operating experience the iTURBO-Blower incorporates “rigid” cartridge style air cushion bearings, not foils. The result is, INVENT say, a dependable bearing without the complexity of active electronic control. The turbo impellers are optimized for the pressure and flow range required by any aeration system, and modelled with computational fluid dynamic (CFD) analysis in addition to test tuning to achieve peak efficiency.
Motor cooling is accomplished with a proprietary “2 pass” pressurised system for maximum heat transfer. As the system is independent of the process air, the blower can be used in extreme environments where ambient temperatures exceed 50° C.
The iTURBO-Blower is an integrated blower package, using Siemens or Rockwell Industrial PLC controllers and HMI panels. All measurement sensors required for the safe and reliable operation of the blower are included within the package. The blower constantly monitors air flow, pressure, and temperatures within the package. A communications connection to the blower allows all operating and diagnostic information such as power consumption, speed, and operating hours to be transferred to the plant SCADA or DCS systems.
To ensure the acoustic enclosure is robust and durable, INVENT have standardised on heavy section zinc anneal sheeting powered coated with 100um heat hardened surface protection. Fasteners, fixings, and hinges on the blower enclosure are SS 316 stainless steel, to ensure all components have maximum life expectancy, as the working environments are usually very harsh.
The iTURBO-Blowers are available in a range from 22kW to 400kW, discharge pressure capability to 150 kPa.
To experience the new technology up close, you can visit the INVENT stand at this year´s IFAT in Munich, Germany, 13-17 May, booth number 327/426 in Hall A2.
