Epiphany's proprietary MVR Crystallizer uses a recirculating evaporator/crystallizer to achieve an efficient zero liquid discharge (ZLD) solution that is extremely compact in size.  The use of mechanical vapor re-compression reduces energy use, while the re-circulation system drastically reduces fouling/scaling on the heat exchange surfaces.

By operating the crystallizer in a fully saturated state, it is equally capable of distilling input water with Total Dissolved Solids (TDS) ranging from zero to 350,000 ppm.  Distilled water output is typically less than 150 ppm, and the solids are discharged as a slurry with a moisture content of only 25-30%.
