Aqua-Jet® SS-PW Surface Aerator For THM Removal
The Aqua-Jet® SS-PW surface mechanical aerator, manufactured by Aqua-Aerobic Systems is certified to NSF/ANSI 61 by UL for use in potable water applications. These units can be utilized for THM stripping applications or circulation in potable water treatment systems and reservoirs with a minimum volume of 100,000 gallons.
THM stripping involves the removal of Trihalomethane (THM), which represents a group of volatile organic compounds formed by the interaction of organic precursors in raw source water and free chlorine added for disinfection.
The Aqua-Jet aerator model SS-PW offers a lower cost aeration solution for THM stripping applications from the perspective of capital, installation and operating cost when compared to diffused aeration or other spray aeration products.
A technical presentation, Aeration Strategies for THM Control, was given by Jacobs Engineering Group on March 9, 2011 as part of the DBP Compliance Approaches webcast that was broadcast by American Water Works Association (AWWA)*. The Jacobs Engineering Group presentation discussed the evaluation of several aeration methods for THM reduction in potable water applications collected from a one-year study. The Aqua-Jet surface aerator model SS-PW was one of the methods evaluated and proved to be an efficient strategy for reducing THMs. The testing also concluded that the Aqua-Jet aerator offers the lowest capital and operating cost compared to the other forms of aeration tested.
