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. 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.

‘Motor coalition’ asks DOE to reconsider proposed energy- efficiency rating change

Alternative suggested for rating increases that could cost hundreds of millions, impact both users and OEMs
Unless simply tired of the subject, almost anyone would agree that in the 21st century energy efficiency is a matter of considerable importance to the process industries. But, as per usual, how to get from here to there can quickly become a matter of heated debate.

The motor itself can also be more energy efficient

Brushless PM motor technology more efficient over broad operating range, author says; use of less costly, readily available ferrite magnets
NEMA Premium efficiency induction motors are considered by many to be the standard for integral horsepower, general-purpose, AC induction motors. While these motors raise the bar for energy efficiency, continuing improvement is both possible and cost-effective.
