WAIV - Wind Aided Itensified Evaporation:
A state-of-the-art enhanced evaporation technology for brine volume reduction/minimization. The device is operated by the wetting of evaporation surfaces, mounted on suitably constructed modules. A pump brings the water from small holding pond or storage tank to a distribution network on top of the vertical surfaces from which the vertical strips are fed by gravity.
The device uses the driving power of wind, which drives away excess humidity from the surfaces to itensify the evaporation process by a factor of 15-20 X more than a conventional evaporation pond.
How does it work?
- Holding pond from which WAIV is fed
- Pump to lift brine to perforated pipes which distributes it to the wetted surfaces
- Wetted surfaces from which brine evaporates
- Impervious surfaces (concrete) sloping back to pond to allow excess brine to return to pond by gravity
Technology benefits
- Extremly low waste volume
- Reduced foot print (Land/CO2)
- Ideal for inland ground water treatment
- Easy retrofit for existing systems
- Compliance with discharge regulations
- Simple and yet reliable
- Modular
- Salable or reuseable byproducts in some applications
- Pilot testing available in Israel
