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.
Mechanical Vapor Recompression (MVR) Evaporator
Saltworks’ VapComp and other MVR evaporators require only electrical power to operate. You may already be reducing your brine volume with membrane systems, an MVR evaporator can help you to take the next step in brine management.
ZERO OR MINIMAL
MVR evaporators use a vapor compressor to evaporate brine and condense distilled water. They 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. They generally come in two types:
- Falling film: wastewater falls down a heated tube, with vaporization occurring on the tube surface. These evaporators are intended for cleaner waters, with less scaling potential.
- Forced circulation: wastewater is heated in a high circulation rate heat exchanger, and evaporates in a vessel, reducing the risk of scaling on heat exchanger surfaces. Forced circulation evaporators are intended for more challenging waters, and when making solids.
Vapcomp for Your Project
Saltworks’ VapComp is a forced circulation MVR, delivered in partnership with leading MVR companies, combining the best MVR technology with Saltworks robust system design, solids management, and automated self-cleaning.
We can engineer an MVR into your total process flow, including consideration of upstream membrane systems. Contact us to ensure that your plant is fully integrated and comprehensively optimized.

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.
A lower cost evaporator crystallizer has emerged – the SaltMaker AirBreather. It is based on the robust backbone of its closest relative – the SaltMaker MultiEffect.
New ultra-high pressure reverse osmosis technology for minimal liquid discharge (MLD) can reduce brine management costs by three times relative to evaporators. Modernized chemical softening technology is available to prevent scaling and enable recovery up to the osmotic pressure limit at 1,200 or 1,740 psi.
