  • Clean in place connections maximize system serviceability 
  • Comprehensive factory testing performed at our ISO9001 certified factory 

 Product Technology

​Reverse osmosis uses a semi-permeable membrane to remove minerals and dissolved solids from water. RO can normally be considered economically attractive on water chemistries with 250ppm ≤ TDS ≤ 2000ppm.  Between 150 -250ppm TDS, local economical considerations and water chemistry will determine whether RO is a viable option. Normally on waters with TDS < 150ppm, ion exchange without RO is feasible for TDS reduction.

A single pass reverse osmosis system typically removes 97% of the total dissolved solids (TDS) and 95% of naturally occurring organics.  The water recovery and average membrane flux usually ranges from 65 to 80% recovery and 14 to 18gfd respectively with both being dependent on the water chemistry. 


​Vantage M86 reverse osmosis and nanofiltration systems come in four different capacities to meet the varied purified water production requirements of our customers. Each system is also available in three different models (Plus, Deluxe and Select) for economy-minded customers to those requiring a more sophisticated system.  ​

For lower capacities please see our Vantage M83 and  M84 reverse osmosis systems.​
