WAIV – Wind Aided Intensified eVaporation (please use the banner from Lesico's Web Site)
What is WAIV? A state of the art approach to providing a highly cost-effective and environmentally friendly approach for evaporation of brine.
The Market One of the pressing problems in applying desalination technologies to the development of new sources of potable water is the disposal of the concentrate at the end of the process. Most of the disposal methods today have impact the environment negatively and are regulated in many countries.
 |
Industrial Brines – concentrated brines (>3%) that cannot be disposed to surface waters or sewers. |
 |
Desalination Brines – where surface disposal is not feasible. |
|
Mineral and mining – tailings ponds, oil pits |
Common Disposal Methods
|
Surface water |
|
Sewers |
|
Brine dilution |
|
Deep well injection |
Our solution: Zero-Liquid-Discharge A process and device based on Wind-Aided Intensification of eVaporation

ED- New modular Electro-Dialysis Membrane Stack
The R&D program New modular design enables excellent flow distribution, low hydrodynamic resistance and no opportunity for clogging of narrow spaces. Hence, Pumping energy is substantially decreased. The new development addresses the negative environmental impacts of reverse osmosis concentrate wastes, by significant volume reduction.
The Market
|
RO (reverse osmosis) brine volume reduction |
|
Brackish water desalination |
|
Industrial wastewater treatment. |
Common methods to treat brine and desalting brackish water Evaporation technologies commercially available today are effective but are considered capital and energy intensive and sensitive to fouling from various biological, organic and inorganic contaminants. These increase the operational costs and can decrease the water quality produced from membranes.
Our solution Our R&D program is aimed to drive down equipment cost, reduce electrical power consumption and to enhance ease of operation and maintenance.
