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.
Water Knowledge Network
Global achievements in UN-water policies and Water
Resource management.
Partners of the pilot project
“The Coronation Pillar Sewage Treatment plant (Phase III–10MGD)”

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 breakdown, 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
