Mega-scale SWRO.

Reimagined.

PowerLine: Optimized SWRO

Power up to ten SWRO trains with one central VFD, improving energy efficiency by 3.5% and savings millions of dollars in capital and operational expense.

Challenges

Membrane biofouling

VFD-related energy losses

Limited pump efficiency

BiTurbo HEMI Rendering Isometric View-400x300

Solutions

Optimized multi-stage SWRO

reduce fouling and extend membrane life

Minimal reliance on VFDs

reduce HVAC requirements and electrical losses

90%+ hydraulic efficiency

optimize pump and motor configuration

Single stage vs two stage RO comparison
RO membranes operate better, foul less, and last longer in multi-stage arrays

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
