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.

How to Manage Brine Disposal & Treatment

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).
