Sulf-IX™ and Sulf-IXC™
Our ion exchange based technologies use resins to selectively remove sulphate and hardness from process waters to produce treated water compliant with sulphate discharge limits and a solid gypsum by-product.

All ion exchange reactions take place in fluidized bed reactors at rise rates that precipitate gypsum without scale formation on the resin beads. And with only the gypsum pore water lost during the process, these technologies can improve water use efficiencies in applications such as cooling towers by removing sulphate to allow for increased water recirculation and re-use.
