  • What is waste activated sludge (was)?
  • Waste activated sludge (WAS) is generated during wastewater biological treatment process and potentially a secondary pollutant if not properly coped with. WAS treatment and disposal accounts for up to 50% of the operating costs in wastewater treatment plants (WWTPs), challenging the municipal wastewater management worldwide 1, 2.
  • What is waste activated sludge (was) & anaerobic digestion (AD)?
  • Waste activated sludge (WAS) is increasingly being produced with the development of wastewater biological treatment processes, and how to dispose of it has become a serious environmental issue. Anaerobic digestion (AD) has great development potential because it needs low energy inputs and can reduce the amount of sludge and recycle resources.
  • What is activated sludge processing?
  • Activated sludge processing is the most widely used biological wastewater treatment technique 1. However, the common occurrence of sludge bulking severely impacts the normal operation of activated sludge biological wastewater treatment systems, affecting the effluent quality and increasing the time required for the system to recover 2.
  • What are the advantages of activated sludge in wastewater treatment?
  • The advantage of the activated sludge process in wastewater treatment is its wide applicability to treat many different types of wastewater, especially for wastewater with high organic matter content; diverse operating conditions (aerobic, anaerobic, and anoxic condition); and save energy.
