SaltMaker MVR & SaltMaker MSF

Mechanical vapour recompression (MVR) and multi-stage flash (MSF) evaporative crystallizers

Achieve true minimal and zero liquid discharge (ZLD) with forced circulation evaporative crystallizer options. SaltMaker MVR requires only electrical power to operate, while SaltMaker MSF operates from thermal energy, including waste heat sources as low as 80°C.

Forced Circulation Evaporators

While you may already be recycling wastewater or producing a high concentration brine that requires crystallization, Saltworks’ SaltMaker evaporators can elevate your project by decreasing energy and chemical inputs and increasing water purity and yield.

 

Saltworks’ forced circulation evaporators do not require expensive chemical pre-treatment and clean themselves while they operate. This is achieved by evaporating inside 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 right materials to protect against corrosion and ensure a long-lasting plant.

Limit Install Costs and Timelines

Our SaltMaker solutions are delivered as factory-built, pre-tested, modular blocks based on a standardized supply chain. This offers our clients several benefits:

  • Secure delivery times and quality: our production facility, engineering, supply chain, and quality control are all under one roof.
  • Rapid site installation: our shippable ISO block plants are quickly placed on footings, interconnected, and started up at your site.
  • 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 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.

In addition to treating wastewater, SaltMaker MVR is also an industry-leading lithium brine concentrator and lithium hydroxide crystallizer

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.
