Saltworks Expertise

Leverage our strengths, knowhow, and innovation engine to benefit your project:

  • Custom and innovative process engineering: including development of comprehensive mass and energy balance models
  • Membrane separations: use our expertise in electrodialysis, reverse osmosis, and nanofiltration taken to the next level
  • Chemical reactions: change water chemistry, selectively precipitate, build the compounds you seek
  • Physical separation: beyond simple filtration, we know how to concentrate slurries and reliably extract solids
  • Thermal evaporation: remove solvents, including water, through thermal separations with unique requirements
  • Crystallization: create and continuously extract salt crystals, employing our robust crystallization systems.

What’s right for you?

We work together with you to develop the best process for your needs. We are technology agnostic because providing you with the right solution is what matters most.


We operate our own production facility with engineering and design at the same location. We can build and quality assure your plant under tight supervision. Given our experience treating the most challenging waters, we also know who supplies the most cost-effective sub-processes and process elements. After spending years automating our plants, we can help automate yours. We can vest this knowledge into your project.
