REDUCE ENERGY CONSUMPTION
  • 5% higher pump efficiency
  • Up to 5% lower energy consumption through elimination of losses and more efficient pumping
  • Handle entire feed flow with c.90% efficient impellers
  • Up to 70% lower HVAC requirements
OPTIMIZE MEMBRANE CONDITIONS
  • Up to 30% longer membrane life
  • Up to 80% higher cross-flow
  • Lower fouling with up to 40% lower membrane beta
  • Smaller second pass: up to 30% lower permeate TDS
IMPROVE PLANT RELIABILITY
  • Up to 50% lower maximum differential pressure for better safety and reliability
  • Eliminate VFD-related downtime by using smaller, easily reparable drives
We are constructing more desalination capacity than ever, but traditional single-stage membrane arrays dominate
 
Small increases to recovery come at the cost of higher biofouling, higher chemical consumption and shorter membrane life
 
Large arrays of isobaric ERDs also struggle to maintain consistent energy transfer, and introduce brine-feed mixing
