The physiology, ecology and population composition of filamentous bacteria in activated sludge
Abstract
Filamentous bacteria play a critical role in the activated sludge process, which is a cornerstone of wastewater treatment systems. These microorganisms contribute to the formation of flocs, influencing the sedimentation properties and overall efficiency of the treatment process. This article examines the physiology of filamentous bacteria, their ecological interactions within the activated sludge environment and the population composition that drives their functional roles. By understanding the dynamics of filamentous bacteria, wastewater treatment facilities can optimize their operations, mitigate operational challenges like foaming and bulking and enhance overall treatment efficacy.
