Advanced Oxidation

Advanced Chemical Oxidation Processes

One of the most effective and conventional methods for contaminant removal is chemical oxidation. Specifically, advanced oxidation processes (AOPs) are frequently used to oxidize non-biodegradable, recalcitrant, and toxic organic pollutants, through in-situ production of reactive radicals. Ozone is another strong oxidant used worldwide to selectively degrade organic pollutants from water. Ozonation was not practical for many years in Israel due to extreme natural levels of bromide (~2 mg L-1) in lake Kinneret, and the concern of forming bromate, the potential human carcinogen by-product of bromine ozonation. In Israel 2016, however, when 75% of water of the drinking water in Israel was supplied by desalination, the relevance of ozonation became significantly promoted.

Zucker Lab focuses on novel design approaches for targeted chemical oxidation applications: 1. Novel in-situ chemical oxidation by passive dissolution of ozone gas for remediation of petroleum-contaminated groundwater: development, optimization, and evaluation of the feasibility of such process to replace current groundwater remediatio

n schemes. 2. Catalytic ozonation processes to enhance the removal of ozone-resist pollutants: hybrid systems for efficient mass transfer of ozone to the treated water, and subsequent conversion to reactive radicals. 3. Adsorption-photocatalysis hybrid materials and processes
