New Advanced Oxidation Process for the Destruction of Micropollutants

Growing concerns among scientists, public health agencies, government officials, and the public have prompted added interest worldwide in the potential health effects of increasingly common chemical contaminants that have been finding their way into our water supplies. These contaminants are used in everything from industry to agriculture to medical care.

To address this challenge, ITT Corporation announce that it has launched a new Advanced Oxidation Process (AOP) concept for the destruction of these micropollutants. The new MiPRO™ process will be marketed under ITT’s WEDECO brand name.

Among emerging contaminants of the most concern in recent years are organic/inorganic substances such as NDMA, MTBE, 1,4-dioxane, pesticides, pharmaceuticals and personal care products (PPCP’s) and other endocrine disrupting compounds (EDC’s), as well as those that contribute to total organic carbon (TOC) and chemical oxygen demand (COD) loading.

AOP solutions typically involve a combination of technologies that can include ozone (O3), ultraviolet (UV) light, and hydrogen peroxide (H2O2) – usually as O3/H2O2, UV/H2O2, or all three agents together.

"We’re the first supplier on the market to offer all three methods from a single source – and even in a single solution," noted Peer Krueger, Marketing Director for Disinfection & Oxidation within ITT Water & Wastewater’s treatment unit. "Our emphasis, though, is on the first as a more effective and economical option." The efficiency and cost effectiveness of an AOP system is highly dependent on the contaminants to be removed and the technology used for treatment. By offering both UV and ozone based AOP systems, ITT can determine the most cost-effective solution based on the site-specific treatment requirements of its customers.

ITT’s Water & Wastewater business will supply the WEDECO MiPRO™ solution in three configurations:

• MiPRO™ eco3 – a WEDECO ozone system, H2O2 dosing unit, an injection/reaction unit and residual ozone destruction system
• MiPRO™ photo – a WEDECO UV system and H2O2 dosing unit
• MiPRO™ eco3 plus – a WEDECO ozone system, H2O2 dosing unit, an injection/reaction unit, residual ozone destruction system and a WEDECO UV system

Krueger underscored the fact that depending on the site-specific requirements the total cost of ownership of ITT’s MiPRO™ eco3 option can be as low as one-fourth the cost of typical medium pressure UV and H2O2 options available on the market today.

"We want to point out that there are more alternatives than medium-pressure UV and hydrogen peroxide when thinking of advanced oxidation processes as other choices may be more efficient and cost-effective, providing a faster return on investment for those considering AOP for their water or wastewater treatment needs," Krueger said.

ITT has been supplying AOP solutions developed at its research and development laboratories in Herford, Germany for more than a dozen years. This WEDECO MiPRO™ concept – i.e., the unique combination of its ozone and H2O2 approach – was developed largely over the past year.
