Saltworks presented innovative case studies at the 2015 WateReuse Symposium that demonstrate new ways to treat some of industries’ most challenging waters. One study focused on a mine water treatment system that solves the centuries-old challenge of calcium sulfate scale—permanently changing water chemistry to enable reliable low-cost treatment.
Another study focused on how enhanced oil recovery (EOR) produced water can be recycled and value added by re-activating the expensive polymer residue left in the water. An assortment of true zero liquid discharge (true ZLD) projects, completed with the SaltMaker Evaporator Crystallizer, was also presented. Catch Saltworks presenting again at the upcoming International Water Conference.
ElectroChem Salt Splitter-RO is the answer to the greatest challenge in mine water treatment: calcium sulfate scale recovery limits. When used on these scaling mine waters, the system resulted in over 96% recoveries and 80% lower cost than a conventional lime-RO-evaporator treatment scheme.
ElectroChem Produced Water Desalter treated EOR produced water from multiple operators worldwide. The system not only desalinates the produced water for reuse, but it also re-activates EOR polymers and increases the viscosity of the water to increase yields.
Also presented were results from Saltworks’ recent true ZLD projects completed with the SaltMaker Evaporator Crystallizer. The SaltMaker treated landfill leachate, oil sands evaporator blowdown, and shale gas produced water to produce high-quality freshwater and solids.

Water plays a critical role in ESG performance for many companies. With growing concerns around pollution ands consumption of water and energy, investing in responsible water management technology can improve your ESG profile and reduce operational risks.
Saltworks’ FlexEDR electrodialysis reversal technology has been selected by a heavy industry client located in Chile to recycle their wastewater. The FlexEDR system, provided in partnership with Chile’s VIGAflow, will use Saltworks’ proprietary IonFlux ion exchange membranes.
Treating RO brine optimally begins with utilizing lower-cost membrane systems to minimize volume for downstream processing. Clients must then decide between the available thermal treatment options that allow for brine concentration or treating down to solids for disposal.
The many options for managing brine, a term for saline wastewater from industrial processes, fall under two categories: brine treatment and brine disposal. Brine treatment involves desalinating the brine for reuse and producing a concentrated brine (lower liquid waste volume), or residual solids (zero liquid discharge).
