Ozone use for removal of Endocrine Disrupting Chemicals continues to gain attention. There are very few oxidants with the potential to remove or successfully bread down EDC’s in wastewater. The use of ozone in water treatment and AOP is continually researched and tested with the anticipation it may be the technology of choice in the future.
A recent article again lays out some new techniques and results of ozone use for EDC removal. Read full article HERE, or see excerpt below.
Newly developed oxidation process uses ozone to degrade contaminants in water
At the Center for Research and Assistance in Technology and Design of the State of Jalisco (CIATEJ) at the east of Mexico, an oxidation process was developed that uses ozone to degrade contaminants in water that alter the synthesis, transport, action or elimination of natural hormones, responsible for maintain self-regulation of metabolic and reproductive processes in living beings.
These compounds represent a potential risk to human health associated with problems in the male and female reproductive systems, and some of them are precursors of breast and prostate cancer.
The research team led by PhD Alberto Lopez at CIATEJ carries out the procedure by gas-liquid reactors, where the water with the presence of such substances called disrupting compounds of the Endocrine System (EDCs) is passed through a gas stream with ozone, which is a major oxidant.
And under certain conditions of temperature, pH, pressure and ozone dosage the EDCs are degraded to less than 95 percent of its initial concentration, exceeding conventional water treatment processes that just reach a 50 percent removal.
EDCs are found in surface water, soil and air. There is great diversity of them, basically solvents, organochlorine pesticides, flame retardants, plasticizers and synthetic and natural hormones.
Oxidation Technologies provides System Integration for both ozone systems and AOP systems for wastewater treatment applications. If you are looking at researching this application or any other with a pilot test or full scale equipment, give us a call. We would be glad to help.
