Advanced oxidation processes for water treatment
Discharge of conventionally treated wastewater results in release of micropollutants (e.g., pharmaceuticals, hormones, pesticides) into the environment, including small streams, rivers, lakes, and the marine environment. They also reach soil and groundwater during water reclamation for irrigation, and they are adsorbed into crops. In Israel, around 80% of the effluents are reused for irrigation in agriculture. In consequence, an adequate treatment in order to remove these micropollutants should be applied. In our research, different oxidation techniques are used such as direct photolysis, UV-H2O2, UV-Na2S2O8, UV-TiO2 for removal of micropollutants from water and effluents.

Nanotechnology for removal of micropollutants in water
Application of nanotechnology open new possibilities for water treatment. The high surface area of nanoparticles possibilities their use as carriers for oxidant species. Moreover, the use of magnetic cores in these nanocomposites will allow their reuse by application of a magnetic field. In our research, we synthetize different kinds of nanocomposites for oxidation of micropollutants in water using enzymes and TiO2.
