Electrical

Typical Power Consumption: 2 – 4 kWh/1,000 gallons of product water

Performance, number of stages and cell pairs, recovery and power consumption are dependent on inlet feed water quality and temperature. A Watsys projection must be completed by an authorized SUEZ Water Technologies & Solutions design representative for proper system design & for any performance guarantee to be provided.
