ITT Research Shows Ozone Oxidation in Wastewater Successfully and Efficiently Treats Endocrine Disrupting Compounds

Business Wire
ITT Corporation (NYSE:ITT), the leading provider of pumps and
systems for the movement and treatment of water and wastewater,
today released the results of a comprehensive study showing that
ozone oxidation is highly effective for treating micropollutants
like Endocrine Disrupting Compounds (EDCs). These potentially
threatening substances, such as discarded pharmaceuticals, can be
found in municipal wastewater effluents. The results were outlined
in a presentation at the North American Regional joint conference
of the International Ozone Association (IOA) and International
Ultraviolet Association (IUVA) in Boston by Dr. Achim Ried,
Director of Research and Development at ITT�s Water and Wastewater
business in Germany.
�EDCs in the water stream are a serious issue in water
treatment, potentially threatening people and wildlife,� said Dr.
Ried. �Ozone oxidation offers proven advantages over traditional
chlorination and other oxidation processes that can�t effectively
deal with organic micro-pollutants like pharmaceuticals. ITT
studied ozone treatment of EDCs at nine wastewater treatment
facilities across Europe over a period of ten years. We found that
ozone treatment usually offers proven advantages for comprehensive
disinfection as well as for color and Chemical Oxygen Demand (COD)
reductions.�
High (more than 90 percent) removal rates are achieved for most
of the investigated compounds by using ozone oxidation, Dr. Ried
said. The studies also showed that ozone treatment ensures
selective oxidation of contaminants, and is more energy-efficient
and cost-effective than other advanced oxidation processes.
Dr. Ried said that ITT is unique in its ability to offer ozone
solutions, as well as ultraviolet (UV) technologies, in combination
with other oxidants, to treat EDC contaminants such as
pharmaceuticals and steroids. When released into water systems by
industry, hospitals and homes, they may adversely alter the
endocrine systems in fish and humans. In view of this hazard,
government agencies in Europe and North America have been moving
forward to enact regulations limiting the level of micro-pollutants
that will be acceptable in municipal water.
�The regulatory principle is preventive action,� said Dr. Ried.
�Even very subtle effects on the endocrine system can result in
changes in growth, development, reproduction or behavior that can
affect the organism itself.�
ITT has delivered its WEDECO� ozone technology for the world�s
first full-scale demonstration at a municipal plant in Switzerland.
After successful trial operations that concluded late last year,
ITT received an order to deliver its technology for a second
full-scale demonstration at another plant, also in Switzerland.
Dr. Ried joined ITT Corporation�s Water and Wastewater business
in 1993, and has served in a variety of technical positions at its
WEDECO� unit in Hereford, Germany over the last 16 years. Dr. Ried
is a member of the German Association of Chemists, the
International Ozone Association, FIGAWA (the German Association of
Water Treatment and Gas Production), and the International Water
Association. He studied at the University of Gottingen and the
University of Marburg, and holds a degree in chemistry, as well as
a doctorate in Environmental Chemistry.
ITT Water & Wastewater is a world leader in transport and
treatment of wastewater and provides a complete range of water,
wastewater and drainage pumps, equipment for monitoring and
control, units for primary and secondary biological treatment,
products for filtration and disinfection, and related services.
