SaltMaker ChilledCrys Crystallizer
ChilledCrys concentrates water and extracts salt. It achieves energy savings by avoiding evaporation.
Evaporators and crystallizers serve two important roles:
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.
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.

* Challenging water chemistry typically means high in organics and/or scaling ions. Saltworks’ other technologies such as XtremeUF and BrineRefine address challenging chemistry upstream of evaporators & crystallizers.
The SaltMaker evaporator-crystallizer family is engineered to meet diverse needs while integrating safety-by-design. Each system is built to maximize uptime through sound engineering to reduce scale, remove corrosion risk, and self-clean during operation.
Scalability and ease of installation and operation is at the heart of every SaltMaker. All four SaltMaker products are constructed using modular ISO shipping container building blocks and are available in different sizes, with configurable options for your application.
Every brine presents unique challenges, and our engineers are ready to review yours. The best solution may involve a cost-optimized blend of technologies. As a manufacturer of membrane, thermal, and chilled concentrators Saltworks is uniquely positioned to optimize treatment economics for the lowest total cost of ownership.

Achieve true ZLD with two forced circulation evaporative crystallizer options: SaltMaker MVR and SaltMaker MSF.
Open-to-atmosphere evaporator, operating at low temperatures to concentrate brine.
Modern, modular, and automated. Reduces brine volume, even to zero liquid discharge (ZLD).
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).
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.
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.
