Learning objectives
You should be able to:• Think creative and innovative about chances for the wastewater
treatment plant of the future….• Select technologies and design treatment chains to fulfill the
needs for the surrounding activities…• In the Netherlands or for your own country• Discuss about chances and defend choices you make

Why Water reuse?
Why:
• Draught;
• Salt;
• Effluent relatively clean compared to other sources.
What :
• Cooling water
• Proces water
• Irrigation water
• Drinking water??

Other measures in sludge treatment
• Sludge desintegration (5 bar, 150ºC)
(More biogas with higher methane content, easier to dewater sludge)
• Fuel Cell
• Supercritical gasification
(Without O2, high pressure (200-400 bar), high temperature (500-700ºC)
conversion of biomass to CH4, CO, N2 and H2)
• More efficient use of energy and low-value heat from CHP
