In what ways is the sludge obtained from a  WWTP used?

Expert Answer:

  • The solid sludge formed in the wastewater treatment plant is transferred to a separate tank where anaerobic bacteria decompose it and produce biogas.
  • The dried sludge is now used as manure, thereby returning the organic matter and nutrients to the soil.
