Advanced brine processing with Dyvar® technology
Industrial complex brines often contain a challenging mix of dissolved salts, organics, and chemicals that are difficult to concentrate or crystallize using conventional technologies.
When brines are aggressive, highly concentrated, or variable in composition, traditional thermal-based systems may struggle, facing issues such as precipitation, corrosion, and energy inefficiency. Dyvar® has demonstrated the ability to reliably concentrate and crystallize these complex brines, delivering consistent and effective results where other systems tend to fall short.

Improve your brine processing with Dyvar®
Dyvar® employs advanced flash evaporation cyclones combined with a high-velocity brine recirculation loop.
In this loop, the brine is heated in a separate heat exchanger, ensuring complete separation between the heating surface and the evaporation surface within the cyclones. This design effectively minimizes scaling and fouling. Thanks to our proprietary cyclone technology and high brine velocity, Dyvar® can concentrate even the most complex brines to exceptionally high levels.
With Dynamic Vapor Recovery, Dyvar® internally recycles the heat it generates, significantly reducing energy consumption. The system can push brines beyond the point of crystallization.
Because Dyvar® can concentrate saline brines beyond the crystallization point, salt crystals are formed and can be separated from the liquid. This enables both fractional and complete crystallization, allowing for the selective recovery of specific salt components.

Frequently asked questions about Dyvar®
Dyvar® is Salttech’s advanced evaporation and crystallization technology, built to treat complex brines and concentrated saline waste streams more efficiently than conventional systems. Using high velocity flash evaporation cyclones, separated heating and evaporation surfaces, and internal heat recycling, Dyvar® minimizes scaling and fouling while pushing brines beyond the crystallization point for selective or complete salt recovery. Below you will find clear answers to the most common questions about what Dyvar® is, how it works, which brines and industries it can handle, and what performance you can expect.
1. What is Dyvar® technology?
Dyvar® is Salttech’s advanced technology for evaporation and crystallization, designed to handle complex brines / concentrated saline waste streams more efficiently than conventional methods.
2. What types of brines can be treated with Dyvar®?
Brines with fluctuating salt composition and varying concentrations, such as those found in produced water from oil and gas operations, mining activities, and other industrial sources. Brines containing high levels of organic compounds, including reject streams from the dairy industry and for example leachate treatment plants. Highly corrosive brines, originating from RO reject streams, ion-exchange brines, and acidic or alkaline process streams.
3. How does Dyvar® technology / evaporator & crystallizer work?
Dyvar® employs advanced flash evaporation cyclones combined with a high-velocity brine recirculation loop. In this loop, the brine is heated in a separate heat exchanger, ensuring complete separation between the heating surface and the evaporation surface within the cyclones. This design effectively minimizes scaling and fouling. With Dynamic Vapor Recovery, Dyvar® internally recycles the heat it generates. The system can push brines beyond the crystallization point, forming salt crystals which can be separated from the liquid. This enables both fractional and complete crystallization, allowing for the selective recovery of specific salt components.
4. What makes Dyvar® unique compared to other evaporation and brine treatment technologies?
Dyvar® is a one-step, corrosion-free, robust evaporation and crystallization technology with modular sizing and energy efficient cyclonic evaporation for treating complex brines. The unique aspect of Dyvar is the use of advanced flash evaporation cyclones, where brine is heated in a separate heat exchanger. This separation of heating and evaporation surfaces prevents scaling and precipitation which are further limited by high fluid velocities in the brine recirculation loop.
5. Is Dyvar® technology an evaporator or a crystalliser?
Dyvar® Technology is an evaporator with crystalliser capabilities. The system can push brines beyond the crystallization point, forming salt crystals which can be separated from the liquid. This enables both fractional and complete crystallization.
6. Why do companies choose Dyvar® over conventional alternatives? Dyvar® offers:
• Evaporation and Crystallization in a Single Step • Engineered for Challenging Brines • Fully Electric, Plug-and-Play Design • Selective Salt Recovery Enables fractional crystallization • Lowest Operating Costs in Its Class • Modular and Rapidly Deployable • Proven Across Critical Industries
7. Can Dyvar® remove salts and provide zero liquid discharge (ZLD)?
Yes. Depending on the salt matrix, Dyvar® can selectively or completely recover salt via fractional crystallization and integrating a Solid Discharge Unit.
8. Can Dyvar® handle extreme conditions?
Yes, Dyvar® is capable of processing high TDS, extreme pH (1–14), organic loads and corrosive brines, also with fluctuations in quality of the brine.
9. What is the heating principle of Dyvar? / Is continuous steam supply needed?
Dyvar® incorporates internal heat recycling through Dynamic Vapor Recovery (MVR principle) and operates without the need for continuous steam supply.
