  • Zero-liquid discharge (ZLD) is a water treatment process in which all wastewater is purified and recycled; therefore, leaving zero discharge at the end of the treatment cycle. Zero liquid discharge is an advanced wastewater treatment method that includes ultra filtration, reverse osmosis, evaporation/crystallization, and fractional electro deionization.
  • Zero liquid discharge can be defined broadly as a process for maximum recovery of water from a waste water source that would otherwise be discharged. This water is beneficially reused and the salts, and other solids contained in the waste water are produced and generally disposed in a landfill.

We offer the following MEE:
  • Forced Circulation Evaporators
  • Falling Film Evaporators
  • Rising Film Evaporators
  • Hybrid or Combination Evaporators

Forced Circulation Evaporators:
  • The liquid is circulated through the calandria by means of a circulation pump, where it is superheated at an elevated pressure, higher than its normal boiling pressure. Upon entering the separator, the pressure in the liquid is rapidly reduced resulting in some of the liquid being flashed, or rapidly boiled off.
  • Since liquid circulation is maintained, the flow velocity in the tubes and the liquid temperature can be controlled to suit the product requirements independently of the pre-selected temperature difference.
  • Falling Film Evaporators
  • WTE specializes in manufacturing and supplying superior quality Falling Film Evaporator. Offered evaporator is designed using latest cutting edge technology under the vigilant supervision of expert professionals. Our evaporator is widely acclaimed by the clients for its superb attributes like consistent performance, high operation efficiency and longer service life. We offer this Falling Film Evaporator in various sizes and specifications so as to meet the varied industrial demands.

  • Excellent heat transfer coefficients.
  • Low temperature operation
  • Optimum heat transfer area
  • Self cleaning action from salting
  • Scaling and fouling
  • Rising Film Evaporators

Rising-Falling Film Evaporator Product Operation:
  • The rising falling film evaporator (RFC), or recirculating version, RRFC, works on uniform metered flow entering the bottom of the steamchest and rises through the first pass with rapidly increasing velocity. After leaving the first pass the flow of the vapor liquid mixture is reversed and directed downward through the second pass at extremely high velocity. The mixture then enters the separator where the vapor and liquid are separated.
  • When not designed as a circulation unit, the rising falling film evaporator provides once through evaporation of heat sensitive materials, requiring minimum retention time. It is particularly adaptable to multiple effect systems but provides a lesser turn-down capability than the RRFC configuration.

Rising-Falling Film Evaporator Characteristics:
  • High tube velocity minimizes fouling.
  • Able to achieve high concentrations at low temperatures.
  • Risk of entrainment is greatly reduced since the major portion of the liquid passes directly out of steamchest rather than being re-entrained with vapor from the separator.
  • System may be turned down without loss of efficiency or effectiveness.
  • Holding time is a matter of seconds (RFC).
  • Suitable for evaporation of a wide range of liquid concentrations.
