उत्तर
Flocs are masses of bacteria embedded in fungal filaments to form a mesh-like structure.
These flocs consume organic matter in wastewater and reduce the B.O.D. levels in the water. The flocs form a part of activated sludge, a small part of which is pumped back into aeration tank to help as inoculums.
