Candidatus Microthrix parvicella has been frequently detected as the dominant filamentous
bacteria in bulking sludge and thus seriously affects the stable operation of activated sludge …

The formation of persistent foams can be a critical problem in wastewater treatment plants
(WWTPs) as it could lead to a series of operational problems, especially the reduction of the …

The new paradigm for used water treatment suggests the use of short solid retention times
(SRT) to minimize organic substrate mineralization and to maximize resource recovery …

Candidatus Microthrix is one of the most common bulking filamentous microorganisms found
in activated sludge wastewater treatment plants (WWTPs) across the globe. One species …

Full‐scale demonstration of activated sludge conversion into a granule–floc hybrid process
was implemented in Dijon (France) water resource recovery facility (WRRF). Biomass …

This paper reviews the problem of foaming associated with the activated sludge process and
its control using various physical, chemical and biological methods. Activated sludge …

Excessive filamentous bacteria growth in conventional biological activated sludge systems
is known to cause issues such as sludge bulking, rising sludge and foaming. Understanding …

Activated sludge plants (ASP) are associated with the stable foaming problem worldwide.
