The Proper Application of Rotary Lobe & Rotary Screw Blower Technology

Written by Kaeser’s system experts, this whitepaper compares rotary lobe and screw blowers, isochoric and isentropic compression, and how to properly apply these technologies for designing an energy-efficient system.

Blower System Integration for Wastewater Aeration Applications

The overall wastewater treatment process is complex, and each step is integral to ensuring water is properly purified. Blower air is an important part of biological wastewater treatment plant (WWTP) processes. Integration—on the blower package level as well as the system level—is key to maximizing energy efficiency and ensuring that this critical service is readily available for the communities the WWTPs serve.

Energy-Efficient System Design for Wastewater Treatment Plants: A System-Splitting Approach

Energy is the single highest operating cost in a wastewater treatment plant, with energy to operate blowers for aeration being the single highest energy consumer. With rising energy costs, it is vital to examine the system’s efficiency and understand how each piece of equipment works with one another and how this interaction impacts plant energy efficiency. This paper outlines the traditional approach to wastewater treatment plant design and the efficiency problems associated with it, as well as explains system-splitting, an alternate design approach with key efficiency gains.

CAGI Data Sheets: Blower Performance Comparison

Comparing blower performances across different manufacturers and technologies has long been a difficult task. For many years, it was all too easy to present data that, though accurate, was potentially misleading. Manufacturers were selective about what information they published, as well as the conditions they chose to specify performance. The result was a numbers game that the buyer frequently lost.
