Best answer
A portion of the activated sludge from anaerobic sludge digester is pumped back to the aeration tank to serve as inoculum.
The anaerobic bacteria digest the bacteria and fungi of the floes.
The anaerobic bacteria in the sludge release CO2, methane etc. during decomposition; these gases from the bio gas is used as a source of energy, as it is inflammable.
