Distillation

Mit Water supplies distillation systems for treatment of high-salinity, high-COD industrial wastewater where conventional biological or membrane treatment is not feasible. Distillation separates water from dissolved solids and non-volatile organics through evaporation and condensation, producing high-quality distillate and a concentrated residue for further treatment or disposal.

Working Principle

Wastewater is heated to its boiling point, causing water to evaporate while dissolved salts, heavy metals and non-volatile organic compounds remain in the liquid phase. The water vapour is then condensed on a cool surface to produce purified distillate. Depending on the application, the system can operate under atmospheric pressure, vacuum, or with mechanical vapour recompression (MVR) to recover latent heat and significantly reduce energy consumption.

System Configuration

Our distillation systems are available as single-effect, multi-effect or MVR configurations. Key components include a feed pre-heater, evaporator body, condenser, vapour compressor (MVR), vacuum system, distillate and concentrate pumps, and a PLC control panel. Heat exchanger surfaces are constructed from SS316L, titanium or duplex stainless steel depending on the corrosivity of the wastewater. Systems are skid-mounted for ease of transport and installation.
