Harnessing 20 Years Of Evolution In Wastewater Bioprocess Aeration

In 2001, when KLa designed its first aeration system, the two most prevalent biological wastewater treatment options were sequencing batch reactor (SBR) and conventional activated sludge (CAS) processes. Today’s options are much broader. Yet, cost-efficient aeration still remains an underlying challenge. This Q&A article provides a look at how the industry arrived at today’s opportunities and where it’s headed for the future.
