Defunct MBBR to EAAS success story

January 16, 2019

We recently upgraded a defunct 435 KLD MBBR (moving bed biofilm reactor) STP to the classic EAAS (extended aeration activated sludge). 

 

L to R: Day 3, Day 4, and Day 6 after conversion.

 

Note that Day 6 is water taken directly from the settling tank (even before passing through activated carbon filter). As clear as any Bisleri, Aquafina, or Kinley!

 

The water clarity improves over time until the population of biological organisms (aerobic bacteria that break down the sludge in EAAS) stabilises.
