The groups of organisms that constitute mesh like structures called ‘floes’ are bacteria and fungi.
These bacterial masses associated with fungal filaments called floes, consume the major part of organic matter present in effluent, thereby reducing the BOD of the waste significantly during biological or secondary treatment of sewage.
Name two groups of organisms which constitute ‘floes’. Write their influence on the level of BOD during biological treatment of sewage.
