7 NethWater BOT credentials (1) Engineering integrity fully based on standards of power and (petro)chemical industry (e.g. redundancy, safety, operational reporting) Contractual liability 100% conformity during last 15 years Liquidated damages for non-compliance NethWater BOT credentials (2) Financial incentives On the downside of contractual KPI s: liquidated damages to Evides On the upside: sharing savings between Evides and customer Technological innovation Only proven technology risk mitigation through cooperation with suppliers of world class Continuous improvement ongoing incentive to enhance production stability while reducing OPEX (research, pilot plant work, training of staff) )

8 Value in the full water cycle Process Water Boiler feed Water Industrial customer Cooling Water Waste Water NethWater focus on the power & chemical industry: Process water (eg: Desalination) Waste water treatment (eg: MBR) Water (Re)use Technology (eg: UF) Water source management Also in Northern Europe water stress is experienced, for example: London City The local rainfall of 600mm/year results in availability of only in 265 m 3 /cap/yr *. This is less than in Israel. Water reuse will increase the availability of water for the urban supply and therefore good water management is integrated into EU legislation: EU Water Frame Directive 2000/60/EC Promoting sustainable water use, protecting available water sources * Source: Planet Water, RWE Thames, London, UK

11 Evides water plant (on the Dow site Terneuzen) Water portfolio Dow Chemical Terneuzen Dow Terneuzen (30 plants) outsourced its water utilities via BOT to Evides. The various water utilities needs are supplied via various feed sources and a number of Evides facilities with various technologies Total utilities: Water supplies: Fresh water: 1,000 m3/h; Demineralised water: 750 m3/h; Condensate return: 1,000 m3/h; Ultrapure water: 1,200 m3/h Water Reuse: Cooling tower supply water: 750 m3/h (reuse industrial effluent); Feedstock IMS to output: 300 m3/h (reuse municipal effluent water). Technologies used: Integrated Membrane Systems (IMS) Ion exchange resins Multimedia filters

16 Developments Chinese water policies New policies developed by NDRC and ministeries e.g.: China Water Conservation Technology Policy Outline, aiming at: Water conservation Efficiency water use Promote sustainable use of water resources Impact developments in Chinese water policy Proposed measures for industry: Promoting re-use Promoting use of seawater Promoting higher efficiency Newest policies: Aiming at zero water discharge

17 Shaanxi Province Shenmu Xian Water management Yellow River The Yellow River Runs Dry In 18 out of the last 26 summers the Yellow River has run dry further and further upstream for longer periods of time. During the summer of 1998, the river failed to reach its mouth at Bohai Bay for over 250 days.

23 Ribbon cutting ceremony June 2010 Demo plant program (jun-oct10) Research of Turning effluent water into a valuable water source, via focus on: 1. Maximum water reuse; 2. Product water quality; 3. Optimum closure industrial water cycle; 4. Residual management; 5. Technical and Economical Feasibility; 6. Fluctuations in feed source; 7. Integration with municipal water treatment plant. Startup June duration of demoplant operation determined via monthly reviews. Presentation to the public via site visits, publications & oral presentation

24 Overall conclusions Global urbanization + industrialization demands good water source policy, legislation and control. Water management will integrate water demand, water availability & sufficient water quality. Turning effluent water into a valuable water source for the Industry. Technologies for water treatment and reuse are available, proven practise and a sustainable environmental solution. Cooperation between different parties in the water cycle is required for maximum efficiency: Industry: end-user of the water; Municipality: supplier of the water, waste water and regulator; NethWater: water utility operator can be the integrator of the parties via BOT contract: Investment, Design, Construction and Operation of the integrated water (reuse) treatment plant Overall conclusions NethWater provides integrated water solutions: integration of know how, designing, engineering and operation; BOT is the business format of choice of NethWater; In case you are interested in our services please contact and meet Mrs. Cathy Feng of Evides China in Beijing
