There are four fundamental types of industrial evaporators and crystallizers used for wastewater treatment, brine management, or improving water reuse. Lower your risks and improve costs by understanding the trade-offs between the different evaporator types.
SaltMaker MVR & MSF Evaporative Crystallizers
Mechanical vapour recompression (MVR) and multi-stage flash (MSF) evaporators
Achieve true zero liquid discharge (ZLD) with forced circulation evaporative crystallizer options:
SaltMaker MVR requires only electrical power to operate,
SaltMaker MSF operates from thermal energy, including waste heat sources as low as 80°C.
MVR AND MSF
ZERO OR MINIMAL
Forced Circulation Evaporators
You may already be recycling wastewater with membrane systems or producing a brine that needs crystallizing; a SaltMaker evaporator helps you to take the next step in wastewater management. In concentrating complex brines or achieving ZLD, many factors need to be considered but uptime and reliability most of all.
Saltworks delivers forced circulation evaporators that do not require expensive chemical pre-treatment and clean themselves while they operate. They achieve this by having evaporation occur in a flash vessel instead of on heat transfer surfaces and employing high shear brine flow through forced circulation heat exchangers and built-in self-cleaning controls. Our technical experts use the correct materials to ensure against corrosions and build a long-lasting plant. We offer a standard 50–200 tonnes per day evaporation rate or custom sizes on request.
Limit Install Costs and Timelines
Our standard SaltMakers are delivered as factory-built pre-tested modular blocks based on a standardized supply chain. This offers owners a number of benefits:
- Secure delivery times and quality: our production facility, engineering, supply chain, and quality control are all under one roof.
- Rapid site installation of shippable ISO blocks that are quickly placed at site on footings, interconnected, and started-up.
- Battle-tested: components and engineering that have been thoroughly field-tested with repeat installations.
- Training and support: we provide onsite technicians to help you install, start-up, and train your team.
MVR Evaporators & Crystallizers
Mechanical vapour recompression (MVR) evaporators and crystallizers use a vapour compressor to evaporate vapour from brine and condense distilled water, recycling the heat of condensation. The vapour compressor provides a temperature rise across the heat exchange. MVRs offer two primary advantages: they only require power to operate (so there is no need for a gas line connection or heat) and are compact.
MSF Evaporators & Crystallizers
Multi-stage flash evaporators and crystallizers use thermal energy to evaporate vapour from a brine, lowering electrical energy consumption and removing the need for a vapour compressor. In a single effect, cooling water is employed to condense distilled water.
In multiple effects, the heat of condensation is recycled to evaporate brine from successive effects. Practically, a maximum of four forced circulation effects is common, while waste heat sources at 80°C may mean employing fewer effects.
Take the Next Step
All SaltMaker MVRs and MSF are built from the same core components, with robust engineering, quality control, and modular packages to lower your total cost of ownership.

SaltMaker MVR and MSF Applications
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.
