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.
Waste Heat-Powered Evaporator Delivered to EV Battery Plant
Treating wastewater, improving sustainability, lowering costs, and providing cooling
July 25th 2022
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.
This installation adds to the growing list of full-scale, waste heat-driven plants delivered by Saltworks, reducing energy consumption and operating costs, while enabling a greener future.

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. Saltworks’ experts can help select the right water recovery and brine minimization system for your needs.

Saltworks 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 with challenging waters and brines. From its headquarters in Richmond, BC, Canada, Saltworks designs, builds, and operates full-scale treatment plants, and offers comprehensive offsite and onsite testing services with its fleet of mobile pilots.
Saltworks has shipped two SaltMaker MVR crystallizers and a SaltMaker ChilledCrys to the electric vehicle (EV) battery industry. These full-scale systems will play an essential role in the production of lithium and nickel—two critical elements in EV batteries.
Saltworks’ SaltMaker AirBreather is the first open-to-atmosphere evaporator-crystallizer with patented technology to guarantee low emissions, making sure your process is regulation-compliant, safe, and future-proofed.
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).
