Location:

The laboratory is located at the school of Mechanical Engineering, Iby and Aladar Fieischman Faculty of Engineering, Tel-Aviv University, Israel

Research topics:

The experimental work conducted in the environmental engineering laboratory covers several topics related to basic transport phenomena and to different treatment technologies. These include:

• Separation processes, mainly liquid-liquid extraction for removal of organic pollutants and/or heavy metals. In particular, continuous and batch Phase Transition Extraction (PTE); application of PTE to treatment of industrial waste water, contaminated soil and sediments.
• Transport phenomena associated with phase transition of partially miscible solvent systems (e.g., free convection, forced convection).
• Liquid-liquid two-phase flow, concurrent and countercurrent flows with and without phase transition, two-phase flow phenomena in small diameter tubes.
• Wind tunnel that simulates velocity profiles in the earth boundary layer for studying pollutants dispersion in the atmosphere.
• Ultraviolet (UV) disinfection and advanced oxidation processes (AOP) of target microorganisms and chemicals intended to improve water-quality through experimental and theoretical work.
• Particle shape from the nano to micron scale in waters, effluents and natural water bodies undergoing various treatments such as granular and membrane filtration, polychromatic UV disinfection and AOP processes.
