Flue Gas Desulfurization Wastewater Treatment

Treat flue gas desulfurization (FGD) wastewater, meet EPA discharge regulations. Achieve true Zero Liquid Discharge.

Achieve extreme freshwater recoveries on scaling flue gas desulfurization (FGD) wastewaters with Salt Splitter. Eliminate expensive soda ash softening, reduce brine management costs, and recover chemicals of value from FGD wastewater.


SaltMaker Evaporator Crystallizer can treat the brine for true zero liquid discharge (ZLD).

Solutions for:

  • FGD wastewater reuse or treatment to meet US Environmental Protection Agency (EPA) discharge limits
  • On-site ZLD
  • Maximize recoveries of existing reverse osmosis (RO) systems

Benefit from:

  • Remove ionic (i.e. CaSO4) scaling limits
  • Turbo charge RO while reducing fouling potential
  • Eliminate chemical soda ash softening, reduce costs
  • Recover chemicals of value such as Na2SO
  • Meet US EPA power generation discharge limits
  • Achieve extreme freshwater recoveries
  • True zero liquid discharge
  • Simple, safe, modular
  • Reduce waste volume, reduce trucking, reduce disposal bills
  • Mobile pilot plants available

Our Technologies

  • Modular, low temperature crystallization for true zero liquid discharge
  • Self cleaning and reliable
  • Produce manageable concentrated brine or solids
  • Extreme recoveries on previously scale limited waters
  • Push RO to osmotic pressure limits
  • Output brines are non-scaling for ease of downstream brine management

Project Summaries

Saltworks' Salt Splitter can treat highly scaling FGD wastewaters with Saltworks' SaltMaker for true ZLD. We have successfully treated some of the world's most difficult wastewaters.
