Activated Sludge Treatment Process Concept and System …
Activated sludge is a sludge particles reduced in wastewater by the growth of organisms in aeration tanks. The term ‘activated’ comes from the fact that the particles teem with bacteria, fungi, and protozoa and is different from primary sludge in the sense that

Troubleshooting Activated Sludge Processes Introduction
www.maine.govOld sludge conditions usually cause a dark brown, thick, scummy foam. It is usually caused by the growth of Nocardia or Microthrix parvicella, both of which grow at the high MCRT/low F/M condition associated with old sludge. A treatment pressure is required to decrease the total sludge units in the system.
