ACTIVATED SLUDGE MODEL By Rudra Narayan Gooptu
Objective Its aim is to treat wastewater in a Wastewater treatment plant where nitrification is enabled
Constituents of the Plant The plant is where the activated sludge process is implemented It consists of:
Flow scheme of Treatment Plant Influent Secondary Clarifier Reactor 2 Anoxic Reactor 3 Aerobic Reactor 1 Anaerobic Effluent Return Sludge
Computations ASM provides the following types of computation:
Maximum Aeration Basin and Sludge Sludge Maximum Aeration Basin
Managing Supernatant The processes involved are:
Extending With Denitrification Process Includes:
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
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
Sludge Treatment using retrievable diffusers Bacteria ( seen under a microscope)
