In sewage treatment, flocs are:
The masses of bacteria associated with fungal filaments.
Flocs are aggregates of microorganisms, particularly bacteria, that are associated with fungal filaments to form a network-like structure. These are formed during the secondary treatment stage of sewage treatment, also known as the biological treatment stage. Flocs consume organic matter in the sewage, breaking it down into simpler substances. The treated water is then separated from the flocs, which are either recycled to maintain the microbial population or processed further as sludge.
