Desalination/ ( Sea water Reverse Osmosis) SWRO

Customers in water-scarce regions find that the Seawater Reverse Osmosis (SWRO) Series from Dew solves their need for desalination while optimizing operating costs. The SWRO Series covers a range of customer applications, including:

  • Boiler and Cooling feed water make-up
  • Irrigation and potable water
  • Plant process make-up water
  • Industrial and Municipal requirements

We understand your water requirements, analyze your water source and perform a cost-benefit analysis to design and integrate a solution that will best meet your needs. Our advanced energy recovery system reduces energy costs while ensuring high quality water. In addition, our approach to SWRO provides a customized solution that uses standard building blocks.

Features of DEW's Industrial & Commercial Reverse Osmosis Systems

This RO system becomes the controller of your water treatment system. By simply activating standard features through a Color Panel view Plus touchscreen HMI, the operation of the pretreatment, RO system, RO tank level, recirculation pump, and post-treatment DM water is coordinated, controlled and monitored. Virtually seamless operation of any system is realized.

Through the DEWTRACKTM service, we can be remotely monitor the entire system and alarms.
