System Evaluation• System operation
– Operation schedules, Control & Monitoring• Purifier operation• Filter operation
– Filtration grade, Self cleaning, Maintenance
• Cleaning system operation• Other component (valves, sensors, etc)

Space requirementsDOQ Upscale (estimate!!)(500 m3/h) (2000 m3/h)
Volume ~ 6 m3 ~ x 4Weight ~ 1000 kg ~ x 3-4Footprint ~ 5 m2 ~ x 2
• Values are without additional piping system which will be highlydependent on vessel!!
• Piping can easily be of the same size as the rest of the system!

Operational cost
• Power consumption ~10 kW / 500 m3/h
• Service; Cleaning fluent, Lamps
• Service cost is overall low
