An anoxic/oxic membrane bioreactor (AO-MBR) and three anaerobic side-stream reactor
(ASSR) coupled MBRs (ASSR-MBR) were operated to investigate effects of side-stream …

The performances of anaerobic-anoxic-oxic processes with (A 2 OB) and without (A 2 OC)
beneficial microorganisms were compared to provide valuable insights on how they are …

Managing sewage sludge effectively is a major challenge in today's environmental
practices. This is due to the rising sludge production and the challenge of finding …

In this study, the biological removal of nitrogen and phosphorous (BNR) was investigated by
applying modified MLE-OSA technique. To conduct this study, three pilot plants scale were …

This paper provides the literature on the investigation of biological organic removals of
monoethanolamine (MEA) in an activated sludge system. A total of 31 papers cited and …

This study proposed a maintenance metabolism based upgraded activated sludge as
MANODOX system that restricts excess biosludge generation from high strength real tannery …

The impact of sludge interchange rate (SIR) on sludge reduction by oxic-settling-anoxic
(OSA) process was investigated. The sludge yield of an OSA system (a sequencing batch …

The oxic-settling-anoxic (OSA) process, which involves an aerobic tank attached to oxygen-
and substrate-deficient external anoxic reactors, minimizes sludge production in biological …

Carbon to nitrogen ratio (C/N) is not the lone limiting factors in biological nutrient removal
from municipal wastewaters, but readily biodegradable to slowly biodegradable COD ratio …

Shortcut nitrification-denitrification (SCND) is widely concerned because of its low energy
consumption and high nitrogen removal efficiency. However, the current difficulty lies in the …
