Permanently change water chemistry

Ion exchange membrane process that splits divalent cations from divalent anions, eliminating scaling potential. For example, Calcium Sulphate (CaSO4) is split into non-scaling CaCl2 and Na2SO4. Split fluids are kept separate, enabling extreme recoveries even on scale saturated waters.

Advanced electrodialysis & RO hybrid systems

Our monovalent selective IonFlux ion exchange membranes are embedded into hybrid processes with reverse osmosis, including EDM options licensed from ZDD, Inc. Overcome scaling limits and achieve extreme freshwater recoveries.

ElectroChem Advanced Electrodialysis E200 stack for industrial wastewater desalination, concentrating reverse osmosis (RO) brines, and replacing chemical softening pre-treatment (lime and soda ash).

Low volume, highly soluble brines

Salt Splitter produces two highly soluble, low volume brines for ease of downstream brine management. Keeping the brines separate prevents precipitation. The two brines can be treated and kept separate within a single SaltMaker Evaporator Crystallizer for true ZLD.

Modular and scalable

Built from Saltworks’ ElectroChem system, utilizing the same stack, automation, and controls. Only the membranes and process arrangement are different. ElectroChem systems are highly modular based on standardized skids and readily containerized for fast dispatch and remote operation.
