Treat and reuse cooling tower blowdown without chemicals, reach true ZLD. Remove salts from circulating cooling water, increase cycles.

Reach true zero liquid discharge (ZLD) with the SaltMaker Evaporator Crystallizer.

Improve recovery of existing reverse osmosis assets with ElectroChem Advanced Electrodialysis. ElectroChem can function as a kidney on the cooling tower to remove specific ions and increase cycles.

Salt Splitter changes water chemistry from scaling to non-scaling, maximizing recoveries.

Solutions for:

  • Treatment of cooling tower blowdown
  • Selective ion removal
  • Improve RO performance

Benefit from:

  • True zero liquid discharge
  • Increase cycles using EDR kidney to remove ions
  • Remove ionic scaling limits
  • Turbo charge reverse osmosis (RO) while reducing fouling potential
  • Increase RO system recovery
  • Soften RO feed, concentrate the brine
  • Reduce waste volume, reduce trucking, reduce disposal bills
  • Mobile pilot plants available



SaltMaker Evaporator Crystallizer

  • True zero liquid discharge (ZLD)
  • Produce freshwater and solids
  • Treat any concentrated blowdown wastewater with little to no pre-treatment
  • Modular design

ElectroChem Advanced Electrodialysis

  • Soften RO feed, concentrate brine
  • Bolt-on to existing RO plants, maximize recoveries
  • Minimal pre-treatment
  • Function as a kidney to cooling tower: remove all ions of concern

Salt Splitter

  • Extreme recoveries on previously scale limited waters
