Features

The VHP Evaporator minimizes the amount of waste that needs to be hauled off-site, and its heat pump technology uses less energy than traditional methods.
The integration of a heat pump circuit provides the necessary heating and cooling to evaporate and then extract clean condensate from the wastewater solution.
The heat pump cycle uses electricity to move heat from one place to another instead of generating heat directly. Therefore, it is five times more energy efficient than conventional electric resistance evaporators.
The system is designed to operate autonomously and without supervision to reduce manpower needs and costs. All models are designed for continuous operation, 24 hours a day, 7 days a week, and require only an electrical supply and compressed air.

Process Description

ENCON Vacuum Evaporator with Heat Pump - PFD
1
FEED WASTEWATER
Wastewater is collected in a holding tank upstream of the evaporator, and fed to the system via the separation vessel.
2
EVAPORATION
The wastewater is circulated by the circulation pump through the main heat exchanger, where it is heated by hot refrigerant. The heated wastewater is then returned to the separation vessel. Upon arrival, flash evaporation occurs.
3
CONDENSATION
The water vapor in the vessel exits to the condenser, where It’s condensed by cold refrigerant. Distilled condensate exits the process via the condensate tank.

KEY DESIGN PRINCIPLES

  1. Evaporation takes place at low temperature and reduced pressure conditions. The pressure in the separation vessel ranges from 0.7 psia to 1 psia. At this pressure, the boiling point of water is 90-102 °F.
  2. Energy consumption: 0.57 kWh/gallon of distillate.
  3. Refrigerant: The ENCON Vacuum Evap uses R513a which has a low Global Warming Potential (GWP) of 573 which is less than half that of competitors systems, is Freon-free, and has an ozone depletion potential of zero.
  4. Continuous flow system: this means that the solution in the separation vessel is maintained at a constant, maximum desired concentration. Concentrate is continuously discharged and replaced by fresh inlet solution.
