The Global Water Treatment market is estimated at $8 billion (2017) and poised to grow and reach approximately $8.6 billion by 2025
LNAPL is a light non-aqueous phase liquid that exhibits a liquid density less than that of water, hence it forms a floating phase that is not soluble in water (e.g., gasoline, fuel oils). There are three types of possible LNAPL contamination: Oil spill at the water surface; industrial wastewater; long-term sources forcontinued ground and underground water contamination. Therefore, the LNAPLs are a great environmental concern. Despite a variety of available solutions, the global community is still searching for a robust, effective and rapid method suitable for both mobile and residual fraction.
Our technology is aphysicochemical method for rapid and effective in situ water purification of LNAPL pollutants (Organic compounds floating on a water surface). The method includes an AOP-based unique combination that contributes to the decomposition reaction rate of LNAPLs, conversion of 99% rapidly (< 1hr).
- This complex disassembles the contaminates into environmentally-friendly end products without producing hazardous side product.
- Relatively inexpensive due to use of a previously developed method for radical production.
- Water pollution due to LNAPLs (Light Non–Aqueous Phase Liquids) is a worldwide problem. The Globally Produced Water Treatment market is estimated at $8 billion and poised to reach approximately $8.6 billion by 2025, according to a report from Research and Markets.
- The technology proposed is relevant for different mediums (waste, sea, and ground water) hence, the complex gives a solution for industrial, domestic and environmental contaminations. Industrial partners could include the electronic industry, water treatment companies, and petro chemical industry.
- AOPs are considered a relatively expensive purification method. Prof. Sasson’s current technology is using an alternative advance AOP agent (not HO). This technology is based on a previously developed unique method for radical production, which was shown to be applicable, effective and inexpensive. This method can be of specific solution in different mediums.
- Easy to implement (including from an airplane) in the case of crude oil spill.
Preliminary results to support the core of the invention were obtained in a laboratory environment - sampleof contaminated industrial waste water (see figure 1).
Next steps are in-situ scale up and pilot
