To purify local water, a water purification system is added to the
system. By assuming an average water demand (4 L/person per day
[44]), 2 m3 of purified water per day are required. Since the power
consumption of the RO system is very low, this technology has been
chosen as the water purification system. In this study a reverse
osmosis water purification system (TW-1.2 K e 225) from Pure
Aqua, Inc. has been chosen as a case reference [45]. The average
load and the peak load during the day are around 8 kW and
16.5 kW, respectively.
