WP2: Intelligent real-time analysis of water quality Sensors – ground water Reservoir level Raw water flow Treated water flow Discharge pressure BW flow Temperature, treated water Filter water level Turbidity, treated water Oxygen, treated water Oxygen, raw water Oxygen, filter specific Conductivity, filtered water pH treated water Turbidity, filter specific UV intensity Filter specific flow Ammonium, filter specific Ammonium treated water Filter specific particle counter NVOC treated water/UVT Present Danish state-of-the-art Priority To be included in WP2 Filter WL RW flow Turbidity Trend Alarm Back wash

WP3: INTELLIGENT PIPE REHABILITATION PLANNING TOOL GIS based software 70% of the assets in a water utility is buried underground Improved selection criteria's means reduced investment costs Suited for export Project generation on street level A holistic technical/economic cost/benefit tool Encompasses socio-economics Transparent selection criteria Can be used on all time horizons 1 & 5 & 20 years Alectia is leading partner

Dynamic reservoir control: Uses reservoirs as huge batteries for storage of energy Reduced costs by using more green power in off-peak periods On-line connection to SCADA system Model based WP4: AUTOMATED SMART-GRID POWER CONSUMPTION TOOL

Pv 1) 6) 5) 4) 3) 2) The model uses 6 construction elements: And 7 Input/output functions: T [Hrs] P [Kr/kW] CO2 [Kg/kW] T [Hrs] Q [m3/h] E [kW] T [Hrs] H [mVS] Q[m3/h] H [mVS] T [Hrs] Q [m3/h] T [Hrs] E [kW]

Output from hydrogeo- chemical model based on specific condition of aquifer Calculation of mobilisation of selected kations (Ca, Ni) Grontmij is leading partner (Hydrogeochemical model made by Aktor Inovation) Unconfined aquifer Confined aquifer WP4: AUTOMATED SMART-GRID POWER CONSUMPTION TOOL

WP5: PILOT PELLET REACTOR (CALCIUM REMOVAL) Product: Manual for design of softening devices Pilot system for testing on specific water qualities Uncovering extent of cation removal (Ni, As, F a.o.) Uncovering relation between pellet shape and water quality Softening perspectives: 50% reduction of soap consumption Reduced energy consumption ~2 x Increased life expectancy for household plumbing Reduced metal contamination of drinking water Increased esthetic value Possible dental adverse effects Pilot reactor to be used on: Brøndby vest WTP (HOFOR) Søndersø WTP (HOFOR) Dalum WTP (VCS) Lindved WTP (VCS) HOFOR is the leading partner
