Pretreatment and RO System for Advanced Manufacturing Customer

Problem: A premier advanced materials manufacturing facility in New England required a constant supply of RO water for manufacturing processes. Permeate of < 10 microsiemens/cm was required. Pretreatment from a municipal water supply was available for RO feed. Peak flow requirements were ~35 GPM of RO permeate

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

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

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