  1. ACTIVATED SLUDGE MODEL By Rudra Narayan Gooptu

  2. Objective Its aim is to treat wastewater in a Wastewater treatment plant where nitrification is enabled

  3. Constituents of the Plant The plant is where the activated sludge process is implemented It consists of:

  4. Flow scheme of Treatment Plant Influent Secondary Clarifier Reactor 2 Anoxic Reactor 3 Aerobic Reactor 1 Anaerobic Effluent Return Sludge

  5. Computations ASM provides the following types of computation:

  6. Maximum Aeration Basin and Sludge Sludge Maximum Aeration Basin

  7. Managing Supernatant The processes involved are:

  8. Activated sludge process helps clean up sewage

  9. Extending With Denitrification Process Includes:

  10. Aeration Process

  11. Introducing Control Mechanisms Control in ASMare of the following types: • On/off control • Proportional control • Aeration Control: oxygen concentration depends upon pollutant load and temperature. Aeration control is of the following types: • On/off control • Temperature control

  12. Denitrification in Secondary Clarifier A secondary clarifier aims at an ideal separation of sludge, and providing a hydraulic hindrance to the wastewater flow The Process Involves: • Formation Of sludge blankets • Consumption of residual oxygen • Formation of sludge islands

  13. Sludge Treatment using retrievable diffusers Bacteria ( seen under a microscope)

  14. Activated Sludge in Different Reactors

  15. Full Treatment Plant

  16. THANK YOU
