ADVANCED OXIDATION PRO

Advanced Oxidation Pro is a consulting company specializes in water and wastewater treatment using advanced oxidation processes (AOPs). The company groups global and local experts in AOP, which cover biological, chemical and engineering aspects of these unique processes. The group is led by Dr. Yaal Lester, which has more than 15-years experience in the development and investigation of different AOPs. The company provides high-level consulting services, as well as projects management, design and oversight, combining industrial and engineering know-how with high level academic experience,

ABOUT THE TECHNOLOGY

Advanced oxidation processes (AOPs) are treatments which rely on the accelerated generation of hydroxyl radicals (OH), one of the most powerful oxidizing agents in nature. OH radicals react and destroy any organic and inorganic contaminants in water and wastewater. The most popular AOPs are based on the combination of ozone or UV light with different chemicals, such as UV/H2O2, ozone/H2O2 and photoFenton (UV/H2O2/Fe). Another high-potential process is photocatalysis, incorporating semiconductor catalyst with UV or solar light. Emerging AOPs include hydraulic and ultrasound cavitation, arc plasma and other OH-generating processes. AOPs are considered the only viable treatment methods for effluents containing refractory, toxic, and non-biodegradable materials, and their major advantages are complete mineralization of organics (without any sludge or waste stream) and easy combination with biological processes

APPLICATIONS

DEGRADATION OF WATER AND WASTEWATER CONTAMINANTS

Advanced oxidation processes are the only commercially available technology able to completely destruct non-biodegradable water and wastewater contaminants. Target compounds include pesticides, taste&odor chemicals, emerging contaminants and more. UV-based AOPs were marked as Best-Available-Technology by the USEPA for tertiary treatment of wastewater for indirect potable reuse

DISINFECTION- INACTIVATION OF PATHOGENIC MICROORGANISMS

Hydroxyl radicals (HO•) can inactivate microorganisms through lipid peroxidation and/or damage to membrane integrity, DNA and proteins. Lipid peroxidation, that is the conversion of unsaturated lipids to polar lipid hydroperoxides, results in decreased membrane ﬂuidity and alters membrane properties

INCREASE WASTEWATER BIO-DEGRADABILITY

Oxidants such as OH radicals are known to degrade large (non-biodegradable) organic molecules into small biodegradable ones. This is usually done through the addition of OH to aromatic rings, which facilitates ring-opening by bacteria in the biological treatment, and allows biodegradation. Treating 'hard' wastewaters with AOP increase the wastewater biochemical oxygen demand (BOD), improving subsequent biological treatment.
