For many companies, water plays a critical role in ESG performance. With growing challenges and concerns around pollution, climate change, and consumption of energy, water, and chemicals, investing in responsible water management can measurably improve a company’s ESG profile while reducing operational risks.
A full-scale, waste heat-driven, Saltworks evaporator has been delivered to an electric vehicle (EV) battery plant. The SaltMaker AirBreather evaporator will treat a highly saline wastewater stream to reduce its volume, reducing the client’s need to truck wastewater offsite.

To do so, it will use waste heat from the manufacturing facility, thereby also increasing the facility’s cooling capacity. This is possible thanks to the AirBreather’s ability to operate more efficiently at lower temperatures compared to traditional evaporation technologies, allowing reuse of lower grade waste heat than previously possible.

Saltworks’ CEO, Benjamin Sparrow, commented “the SaltMaker platform was originally developed to treat oil and gas produced waters, leveraging waste heat when available at production sites. We are thrilled to see this technology adopted at full-scale in the electric vehicle industry. Saltworks is proud to help clients from all industries to achieve lower operating costs and improve their sustainability metrics.”
The SaltMaker AirBreather was developed with support from Canada’s National Research Council’s (NRC) Industrial Research Assistance Program (IRAP) and Sustainable Technology Development Canada (SDTC).
Saltworks’ SaltMaker evaporative crystallizers are available with different configurations optimized for the wastewater and energy source, and may be electrically or thermally driven.

About SaltworksSaltworks Technologies is a leader in the development and delivery of solutions for industrial wastewater treatment and lithium refining. By working with customers to understand their unique challenges and focusing on continuous innovation, Saltworks’ solutions provide best-in-class performance and reliability. From its headquarters in Richmond, BC, Canada, Saltworks designs, builds, and operates full-scale plants, and offers comprehensive offsite and onsite testing services with its fleet of mobile pilots.
Our SaltMaker modular evaporators and crystallizers turn almost any wastewater into clean water, minimal liquid discharge (MLD) brines or zero liquid discharge (ZLD) solids.

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).
