Masses of bacteria associated with fungal filaments to form mesh like structures, what is it called ?

Flocs

The primary effluent is passed into large aeration tanks where it is constantly agitated mechanically and air is pumped into it. This allows vigorous growth of useful aerobic microbes into flocs (masses of bacteria associated with fungal filaments to form mesh like structures). While growing, these microbes consume the major part of the organic matter in the effluent.

Masses of bacteria associated with fungal filaments to form mesh-like structures are called flocs. Flocs are formed during the biological treatment or secondary treatment stage of sewage treatment. In this stage, aerobic microbes, including bacteria and fungi, grow and aggregate together, forming flocs. The flocs consist of a complex matrix of microbial cells, extracellular polymers, and fungal filaments. These flocs help in the removal of organic matter from the sewage by providing a large surface area for microbial activity and facilitating the settling of solids during the sedimentation process. Flocs play a crucial role in the treatment of sewage by enhancing the efficiency of organic matter degradation and improving the overall quality of the treated effluent
