The Challenge

A premier advanced materials manufacturing facility in New England required a constant supply of reverse osmosis (RO) water for its manufacturing processes. Permeate of <10 microsiemens/cm was required. A municipal water supply would be feeding the facility, requiring RO pretreatment to be designed and put in place ahead of the RO. Peak flow requirements were ~35 gallons per minute (GPM) of RO permeate.

Our Solution

Pure Flow designed a custom high purity water solution with the following components:

  • Backwashing duplex parallel carbon tanks for dechlorination and RO pretreatment
  • Backwashing duplex alternating water softener for hardness reduction and RO pretreatment
  • Suez E4-H Reverse Osmosis – 4″ membranes, horizontally-oriented membrane housings

The complete system was pre-piped and skid mounted at our facility prior to shipment to site for start-up and commissioning. The system operates flawlessly and meets all customer specifications.
