When a reduction of dissolved solids from a water supply is required, MPW’s reverse osmosis (Mobile RO) trailers offers a versatile solution. Reverse osmosis is a membrane process that provides a physical separation of the supply water into two streams, permeate and concentrate. 

Reverse osmosis (Mobile RO) can be used to improve numerous industrial water treatment processes. The system provides the ability to vary flow rate with changing influent water quality conditions and production requirements. The system is operable in either single-pass or double-pass mode.

As pretreatment to ion exchange demineralization, reverse osmosis provides a significant reduction in regeneration of chemicals. Many water recovery and reuse projects require RO, such as cooling tower blowdown reduction, holding pond dewatering and wastewater reuse.

MPW's multi-pass 200, 300 and 600 Mobile Reverse Osmosis (Mobile RO) systems provide varying flow rates and onboard filtration and are convenient production solutions for recovering dissolved solids, Total Organic Carbon (TOC) and other colloidal contaminants. ​

Reverse Osmosis System Features:

  • Quick conversion to single-pass or double-pass operating mode
  • Removes up to 99% ionic contaminants and organics over 200 molecular weight
  • 24-hour remote monitoring
  • PLC controlled chemical feed systems for de-chlorination, pre-filtration, scale inhibiting and pH control
  • Full system automation / touch screen controls
  • Onboard filtration

Typical Applications:

  • Total dissolved solids reduction
  • Colloidal silica reduction
  • Water system outage support
  • Organic compound reduction
  • Demineralizer system pre-treatment
  • Environmental improvement and waste discharge reduction
