Multi Vapor Recompression Distillation
Multi Vapor Recompression Distillation is a unit operation, It Helps to reduce TDS at very high Concentration.
Process Description :-
Mechanical vapour Recompression distillation of saline water is a process in which mechanical energy is used as the main driving force. It is basically a heat pump process that pumps heat from a low-temperature reservoir to a higher temperature reservoir, just as in household refrigerators where the heat is pumped from the air inside the refrigerator box to the ambient air outside of the box. In a vapor compression distillation of saline water, the system is not a closed cycle and the basic system consists of the evaporator-condenser and the compressor. The working fluid is water vapor. Water vapor generated from the water layer on the evaporation side of the heat transfer surface is compressed to raise its saturation temperature and pressure and is then condensed on the condensation side of the heat transfer surface, forming condensate and releasing the latent heat of condensation to be transferred across the heat transfer surface into the water layer on the evaporation side to cause further evaporation of water.
Target Impurities :-
- TDS
- Free Radical Ions
Advantages :-
- For any dissolved salts Rejection upto very 99.9%.
- Quality of treated water is very good.
- Low Opex cost.
