Demonstration Project

in Wastewater Treatment


Danish Water Forum

in cooperation with Delhi Jal Board

IIT Delhi, 22nd September 2011

Mr. Lars Christensen

Deputy Head of Mission, Royal Danish Embassy

Danish Water Forum

Indian-Danish Water Days February 2009

  • State-of-the-art technologies

  • Market opportunities:

  • Wastewater Treatment

  • Cost savings

  • Agreement of a Demonstration Project

Meeting of the Prime Ministers September 2009

  • Access to CO2 reducing technology

  • Cooperation in the areas of environment

  • Involvement of The Danish Ministry of Environment

Demand For Better Water Quality

Motivation for The Demonstration Project for Danish Companies is

to upgrade existing plants with new technology that ensure:

  • Energy Optimization

  • Improvement of Treatment Process:

  • Optimization of The Discharge Profile

  • Reduction of Bacteria Levels

  • Reduction of Pollution

  • Staff Training

Signing of MOU 22. November 2010

For the collaboration between Delhi Jal Board and Danish Water Forum for the demonstration project:

“The Coronation Pillar Sewage Treatment plant (Phase III–10MGD)”

Danish Water Forum(DWF) was established 2003

Umbrella-organization consisting of companies and organizations with different approaches to the market.

Electricity consumption for waste water treatment plant (activated sludge)

Comparison of investment share vs. energy consumption share

In the secondary treatment phase waste water is treated by means of bacterial breakdown of the dissolved biological waste.

In order to foster this bacterial break-down, the oxygen level of the water needs to be correct, not to high nor to low. Aeration is the process by which the area of contact between water and air is increased, either by natural or mechanical

means, resulting in air being suspended in water.

Investment share Aeration blower of total plant

Electricity consumption share of total plant

Scope of evaluation without distribution pumping stations

Why efficiency should be point of interest?



OPEX on energy cost

OPEX on Compressor energy cost

Because the 2% initial cost ties up the client with a 55% energy

bill to pay during the next 20 years

Treatment Plant

The Coronation Pillar Sewage Treatment plant

(Phase III – 10 MGD)

Main objectives with the upgrade

Upgrade the facility without civil changes, and optimization

of the facility by adding:

  • Energy Efficient Pumps

  • Aeration Systems

  • Sensors and Controlling Hardware

  • Data-Collection System

  • Chemical/Biological Optimization Analysis

  • Capacity-Building (Training of the staff)

Energy savings used for payback over agreed period
