Activated sludge model

  • ACTIVATED SLUDGE MODEL

By

Rudra Narayan Gooptu


Objective

Objective

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


Constituents of the plant

Constituents of the Plant

The plant is where the activated sludge process is implemented

It consists of:


Activated sludge model

Flow scheme of Treatment Plant

Influent

Secondary Clarifier

Reactor 2

Anoxic

Reactor 3

Aerobic

Reactor 1

Anaerobic

Effluent

Return Sludge


Computations

Computations

ASM provides the following types of computation:


Activated sludge model

Maximum Aeration Basin and Sludge

Sludge

Maximum Aeration Basin


Managing supernatant

Managing Supernatant

The processes involved are:


Activated sludge model

Activated sludge process helps clean up sewage


Extending with denitrification

Extending With Denitrification

Process Includes:


Activated sludge model

Aeration Process


Introducing control mechanisms

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

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
