Mechanical Vapor Recompression Evaporator
Mechanical Vapor Recompression (MVR) Evaporator

The Mechanical Vapor Recompression (MVR) evaporator is engineered to separate waste from water through distillation. This water reclamation system reclaims up to 98% of your wastewater as clean water that can be reused in your industrial processes. The remaining residual waste is collected in a concentrate for disposal. As a result, this system substantially reduces your wastewater disposal costs and minimizes your environmental footprint.

One of the main advantages of the MVR is its low energy consumption, making it one of the best on the market. It evaporates the wastewater under vacuum without heat sources such as electric heaters, gas burners or steam. In addition, since no cooling water is required for the vapor condensation process, your cost savings are even greater.

MVR evaporators are at their best when evaporating large quantities of dilute solutions such as metalworking fluids and rinse waters common to surface treatment parts washing or fluorescent penetrant inspection lines (FPI).

The MVR uses a compressor to increase the pressure of the steam produced. An increase in pressure also increases the condensation temperature of the steam, rendering it usable to heat the original mixture in a heat exchanger. It is this resulting temperature difference produced by compressing steam that enables a highly efficient heat transfer to occur.

As the steam condenses in the heating chamber, it releases its latent heat through vaporization to further heat the original mixture, which in turn produces more steam.

Principle of Operation

  1. Incoming waste water is pre-heated by the heat available in the distillate being produced.
  2. The waste water evaporates under a partial vacuum in the main heat exchanger.
  3. The evaporate (steam) is compressed and returned to the main heat exchanger, where it is condensed. This releases all of the latent heat back into the system.
  4. The condensate is released in the form of a high-quality distillate, ready for re-use or disposal.
  5. The waste water undergoes continuous concentration to a minimum level, where it is then ejected for waste disposal.
