  1. The Trade Council of Denmark Demonstration Project in Wastewater Treatment by 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

  2. Indian-Danish Water Days February 2009 • State-of-the-art technologies • Market opportunities: • Wastewater Treatment • Cost savings • Agreement of a Demonstration Project

  3. 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

  4. 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

  5. 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)”

  6. 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.

  7. Partners of the pilot project “The Coronation Pillar Sewage Treatment plant (Phase III–10MGD)”

  8. Water resources Groundwater resource mapping Water resource planning Surface water hydrology Water treatment Planning Design Rehabilitation Rural water supply Water quality Monitoring Groundwater contamination Water distribution Planning Design Rehabilitation Rural water supply Receiving waters and wetlands Receiving water studies Nature restoration Water usage Water savings Cleaner technologies Wastewater treatment plants Design Upgrading Operation Sewerage Planning Design Rehabilitation Sanitation COWI - Water circle • Integrated services: • Water sector programming and planning • Integrated water resource management • GIS and modelling • Economics • Water pricing and tariffs • Regulations/legislation • Capacity building • Institution building • Public/private partnership • Operations management • Supervisory control and data acquisition • Environmental management

  9. Danfoss’ core businessesfocus on Climate & Energy

  10. Danfoss’ Dedicated VFD for all applications in Water, wastewater & irrigation • Over 25 year track record globally & in Asia Pacific • 1000’s of Drives & Soft Starters in service • Water supply & treatment • RO / Desalination & recycling • Wastewater treatment • Pumping Stations • Irrigation • Power generation • District heating • Waste processing & recycling

  11. Siemens Turbomachinery SolutionsSelection of Municipal Wastewater treatment references Largest in world Largest in Europe Largest in S. America Changi WRP (SIN) 2.4 mio m3/day 10 x KA80SV, 2002 Seine Aval WWTP (FR) 1.7 mio m3/day 15 x KA22SV, 2004 La Farfana Santiago (CI) 760.000 m3/day; 50% of population of Santiago 6 x KA66SV, 2001 Largest in Italy Largest in China Pudong Bailonggong (CN) 2.0 mill m3/day 12 x KA22SV, 2007 Milano South WWT (IT) 1.050.000 P.E. capacity 50% population of Milano 4x KA66SV, 2003 Al Ansab WWTP (OM) 220.000 m3/day; 900.000 P.E. 3x KA80SV, 2005

  12. Fruits on the ground: Where is the biggest fruits? 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. 2 3 1 ~3% ~54% Source: Water Environment Federation Energy Conservation Task Force. Energy Conservation in Wastewater Treatment Facilities. 1997 Investment share Aeration blower of total plant Electricity consumption share of total plant Scope of evaluation without distribution pumping stations

  13. Why efficiency should be point of interest? CAPEX CAPEX + OPEX 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

  14. Treatment Plant The Coronation Pillar Sewage Treatment plant (Phase III – 10 MGD)

  15. 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)

  16. Energy savings used for payback over agreed period “Pay as you benefit” solution The “Pay as you benefit” concept

  17. Financing DJB Partners
