PROflex LT Brackish Water Reverse Osmosis & Nanofiltration Systems

Robust, flexible, and economical systems for light industrial and commercial applications

The PROflex LT is both an evolution of popular E-Series systems and an extension of the municipal and more industrial focused PROflex product line. With this new offering, you can continue to expect the quality and durability that all Veolia systems provide. The PROflex LT will have the optimized simplicity and economics expected of E-Series systems but incorporate the powerful combination of further cost savings and configurability in the existing PROflex systems. 

Light industrial and commercial applications: 

  • Car washes 
  • Commercial/industrial boiler feed water 
  • Humidification systems 


True Flexibility to Design a System You Want 

PROflex LT offers the flexibility to choose an aggressive or conservative flux and design to meet the capital requirements of your specific situation. You can further explore all of the customizable models below by just providing simple operational inputs into the Veolia flexConfigurator.
