HEVAP™ High Efficiency Evaporation

Reliability is vital for Zero Liquid Discharge (ZLD) operations. At Aquatech, we have extensive experience designing ZLD plants which has led to the development of our patented HEVAP™ High Efficiency Evaporation technology. HEVAP™ pre-conditions the feed water by incorporating a softening step combined with additional conditioning of the feed water prior to treatment by the evaporators. This process provides the evaporators with essentially a scale free environment in which to operate. As a result, this allows evaporators to be more efficient with less downtime and longer runs in between evaporator cleanings.

HEVAP™ Advantages

  • More availability than conventional evaporator (up to 100%)
  • Reduces the frequency of washing/cleaning
  • Handles brackish water make ups
  • Higher recoveries
  • Lower operating expenses (OPEX)
  • Lower life cycle costs (LCC)
  • No EDTA dosing required
