What power components were included in our 50 mgd NPV model?
The NPV model used estimated allowances for the total treatment power including raw seawater intake pumps (200 ft-head), pre-filtration pumps (105 ft-head), the actual RO process number from the ADC pilot, product water lift pumps (40 ft-head) and product water finish pumps (200 ft-head). For the first set of SW30HR-380 membranes, the total treatment power from our NPV model at the MAP was 10.67 kWh/kgal (2.82 kWh/m3) verses 7.15 kWh/kgal (1.89 kWh/m3) for the RO process alone.
