The need for brine minimization

Evaporation Ponds –
Land Intensive Solution

Saline Water Basin

Fresh water scarcity and concerns for environmental impact resulting from industrial use place a high degree of importance on recycling and reuse of inland water sources. Since the beginning of the 20th century, industries where traditionally located next to water sources for effluent disposal. These industries are gradually moving to inland locations where disposal is not trivial at all.

Industries that contribute to pollution in inland locations include but are not limited to desalination plants, mining, agricultural applications and power stations.

Following more than three decades of continuing expansion of sea water desalination capacity at coastal sites, considerable interest has now shifted to inland water sources.

Many inland desalination facilities possess ample underground reservoirs of saline water and deserve special focus as they generate large volumes of rejected waste. However, their design presents greater challenges than building a similar facility at a coastal location. Even with the use of conventional brine minimization technologies for high product water recovery, the volume of highly concentrated plant discharge streams can still be very large and costly to dispose.

There are several means of disposal of concentrate that are practiced worldwide. These include: surface water discharge, disposal to front end of sewage treatment plants, deep well disposal, land applications and evaporation ponds.

Not all disposal options are available at a given location due to climate, geology, soil conditions, distance from plant, level of local public concern, and the local regulatory position. Inland desalination plants have few or no cost-effective and environmentally sustainable disposal methods.

Lesico CleanTech profile

Lesico CleanTech is a private cleantech company with a business focus on developing and commercializing sustainable technologies which recycle or significantly reduce the volume of liquid waste, primarily desalination rejected brine. The solutions not only help users comply with stringent regulation, but results in substantial savings in real estate, installation and operational costs.

The company was founded in Israel and over time has patented a number of platform treatment technologies which enable liquid waste minimization by enhanced evaporation and a cost effective high recovery desalination process with an innovative electro dialysis membrane stack. Our products and services are designed to reduce significantly the acquisition and operation costs of inland brine discharge installations and optimize the use of natural resources and provide significant reduction in footprint.

While clean water technology development and commercialization is our main function it is also a key to addressing the needs of our clients who seek cost effective sustainable brine discharge solutions which comply with ever growing stringent regulations aimed to prevent contamination of ground&water resources. We also provide our clients with specialized advisory services for implementing the value-added solutions.

Lesico CleanTech participate in collaborative research and development projects with the department of water research in Ben Gurion University (BGU) and the support of the OCS (Office of the Chief Scientist) in Israel. The company enjoys a direct interface with BGU’s world experts in environmental hydrology, microbiology and meteorology and continuously exploring for innovations that will expand its product base and value proposition.

The WAIV (Wind Aided Intensified eVaporation) system is a commercially available proprietary technology that has been widely demonstrated and licensed outside of Israel. Successful commercial beta unit tests are operated in Israel, Australia and Mexico.

We provide access to our technologies through flexible licensing, EPC or project partnership arrangements, as appropriate.

Lesico CleanTech Mission Statement

Lesico CleanTech seek to position itself as a world leader in zero liquid discharge technologies, to offer its customers with an entire range of environmental services to enable efficient desalination and other industrial processes which requires cost effective discharge solutions, while committed to sustainable development practices.
