• Mind setting:– Water business & sustainability is unique
• Water COLD ≠ energy
• Water = team play
• Water in the region & current performance
• Water quality
• Conclusion:– COLD water independent of oil price & other raw materials– Water price < 1 ‰ of total industrial production cost– Regional water issue– Scarce water sources first to households = hygiene first– Industry can perform with less quality– Quality control & ultra pure come first in industry– Sustainable quantity improvements will then follow

Solving global problems• Most people will (soon) live in mega cities than instead of rural areas
• Most mega cities will be situated in a river delta or at the coast.
• Health and safety risks will increase
• Pressure on the water systems will grow
• PPP is a solution to these challenges
• Household wastewater recycling concept: – Urban regions with water problems– Source for local industries
• Key elements: = Time & Temperature & Risk Mgt. &. ….Science & Technology (= TUD)
≠ €’s & ultra pure

• Science & technology regarding water & energy chain– Reference potable water= heating ≤150 Wth.household-1public oblivious – Potable water = hygiene ≤ 10 We.household-1 = 50 kg CO2.a-1
– Municipal waste water = ecology ≤ 20 We.household-1 for O2 mainly
– Industrial water = risk mgt ≤ 60 We.household-1 for RO mainly
• 5 – 50 years time table to incorporate the water chain– Industrial water integral part– Complex chemical matrix & ultra pure needs– Natural follow-up for existing potable & municipal waste water– Science & technology approach is unique & consistent
• COLD water independent of oil price & other raw materials• “gezondheidstechniek” of Water mgt at Civil dep. Dia 62; oil- & water- price since 1989 - 2005• Sanitation basics = 1.000 m3.a-1.household-1 including rain.• Energy basics = 6 kWth per person• Transport: 1 m3 * 1 bar * 10 mWk.bar-1 * 9.8 m.s-2 * 103 kg.m-3 = 100 kJ per m3 water• Heating: 1 m3 * 25°C * 4.18 kJ.kg-1 * 103 kg.m-3 = 100 MJ per m3 water• Compressing: 1 Nm3 air * 1 bar * 104 kg.m2.bar-1 * 9.8 m.s-2 = 100 kJ per m3 air.• Compressed air below 1 mWk = 2,000 kJ per kg oxygen .

• Road to sustainable integral chain of events; internal factors– Back to Basics:
• Focus on previous, current and next water user
• Trouble free exchanger life time for decades = every pipe centuries• 2 mm of carbon steel only• Energy conservation = clean heat exchangers• Reliability = clean heat exchangers• Thermodynamics: predict clean heat exchangers
H2O = (re-use as) cooling water & customer vulnerability

• Accept industry as part of the solution– Public Private Partnership PPP = regional integration– Potable water first for the “kids” = hygiene– Municipal waste water to industry= €
• Delivery– Multi raw water sources– Reliability of delivery & ultra pure– Sustainable water source
• Dow Terneuzen– 50 % internal water recycle
• 80 % sweet WWTP re-use
– Energy savings• 55 kTon CO2 equivalent = 90 % of 240 kJ.kg-1 demiwater MSFE• 2 kTon CO2 equivalent = 65 % based on RO-salt to RO sweet
