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).
SaltMaker Evaporators & Crystallizers
Modernized evaporators and crystallizers for reliable minimal and zero liquid discharge
Our SaltMaker family of robust modular evaporators and crystallizers can turn almost any saline wastewater into clean water, minimal liquid discharge (MLD) brines or zero liquid discharge (ZLD) solids.
Evaporation & Crystallization Reinvented
Evaporators and crystallizers serve two important roles:
- Concentrating and crystalizing valuable input materials to everyday products
- Achieving minimal liquid discharge (MLD) from wastewaters, or achieving zero liquid discharge (ZLD)
When conventional membrane concentration options are exhausted, evaporation and crystallization solutions are the natural next step. Our SaltMaker evaporator crystallizers operate on challenging industrial brines without complex pre-treatment thanks to their forced circulation and self-cleaning designs. They are engineered to withstand corrosion, minimize site installation costs, and maximize uptime through robust design and intelligent automation.
Whether you seek concentration and minimal liquid discharge (MLD) via an evaporator, or salt crystallization and zero liquid discharge (ZLD) via a crystallizer, there is a SaltMaker suited to your project’s treatment goals.
SaltMaker: Meet the Family
Our SaltMaker family provides scalable, flexible solutions that cover all evaporation and crystallization needs, including MLD and ZLD. We offer five versions tailored to specific end-user needs and energy sources. Each version has a fit case. Volatile organic compounds and ammonia that evaporate with water vapor can be effectively managed to ensure high-quality clean water.

The SaltMaker MultiEffect evaporator crystallizer is a one-step brine treatment plant for volume minimization and zero liquid discharge (ZLD) applications. Its unique evaporative crystallizer design is built to treat the toughest waters and to simplify your brine treatment project.
Zero Liquid Discharge (ZLD) and Minimal Liquid Discharge (MLD) Become Lower Cost Through Reverse Osmosis Innovation
Saltworks is pleased to announce that recent advancements in reverse osmosis technology are now commercially available. Reduce conventional RO brine volumes by 50%, achieving brine concentrations of 130,000 to 150,000 mg/L TDS with spiral wound RO membranes.
Convention teaches that ZLD requires energy-intensive boiling to produce solids. Our engineers recently broke that convention and helped a mining client achieve solid salt production in a novel membrane-chiller hybrid plant using UHP-RO.
