ENCON MVC Evaporator Process Description (Refer to diagram below)
- Unheated wastewater is fed to the liquid vapor separation tank (1) and is heated to a boil by the electric heating element (6).
- Recirculation pump begins circulating heated water through the main heat exchanger (2) and back into the separation tank (1).
- Steam flows up through the mist pad (8) to inlet side of vapor compressor (4).
- Compressed steam from vapor compressor (4) is forced through the steam side of main heat exchanger (3) giving up latent heat to the counter flowing water from the separation tank (1).
- High temperature distillate flows out of the main heat exchanger (3) to feedstock heat exchanger (7) giving up sensible heat to feedstock wastewater.
- Upon reaching steady state, cold feedstock wastewater is fed at a constant rate through the feedstock heat exchanger (7) to raise temperature before feeding to recirculation loop.
- Concentrate is periodically discharged based on conductivity probe (11) from separation tank (1) to concentrate tank (9) through residue pump (10).
