E-Series Features

RO is used to remove residual salts and other aqueous species from your water. RO involves the reversal of flow through a membrane from a high salinity, or concentrated, solution to the high purity, or "permeate", stream on the opposite side of the membrane. Pressure is used as the driving force for the separation. Veolia’s RO systems offer reliability, ease of operation, cost savings, consistent water quality treatment, and improved removal of contaminants. Other E-Series RO benefits include:

  • Skid-mounted and ready to use with complete system delivery
  • No assembly; plug-and-play simplicity
  • Easy to order, with configure to order options
  • Complete factory support for any and all inquiries
  • Drawings and manuals available by contacting your Veolia's sales representative
