The main aim of this study was to find the relationship between the operational parameters and morphology of sludge flocs. Simultaneously, the variations in floc size along activated sludge chamber were studied with respect to the oxido-reductive conditions.

BACKGROUND Ammonium oxidizing bacteria (AOB) have been suggested to have a lower oxygen half‐saturation index than that of nitrite oxidizing bacteria (NOB), …
—Purification of waste water is commonly done using the activated sludge process. The ratio of the activated sludge flocs and filamentous bacteria play a key role in the purification process of waste water. The sludge bulking or filamentous bulking
Activated sludge floc morphology and nitrifier enrichment can explain the conflicting reports on the oxygen half‐saturation index for ammonium oxidizing bacteria (AOB) and nitrite oxidizing bacteria (NOB) Jun Wu. Corresponding Author. E-mail address: jun.wu08@gmail.com.

of activated sludge flocs in full-scale WWTPs, and 2) determine the effects of floc morphology on sludge settleability and effluent suspended solids levels. 2. Materials a nd Methods 2.1. Sample Collection Mixed liquor and effluent samples were collected from three full-scale activated sludge wastewater treatment plants (WWTPs) in Accra, Ghana.
Activated Sludge Activated sludge is a type of secondary treatment whose primary role is to remove most of the dissolved solids remaining in the waste stream after
The presence of bacteria is vital for the wastewater treatment process. In an ideal wastewater treatment plant system, bacteria (about 95%) along with a small portion of fungi and protozoa should form a biological floc that is known as an activated sludge. This is essential for the degradation of organic substances in wastewater.
