50F5 Modular Ionizers

• Ionizer modules can be rack or flange mounted to fresh air inlet duct or recirculation plenum or duct

• Power consumption only 50 watts per module

• Oxygen present in air flow over tubes becomes bipolar - ionized and reactive

• Ionized air flows via HVAC air distribution ducts to building or enclosure

• No ozone produced.

And Ionization of VOCs Shown to be Effective

• Ammonia

• Acetic Acid

• Acetone

• Butyl Alcohol

• Carbon Monoxide

• Chloro Benzene

• Chloroform

• Dimethyl Disulfide

• Diethylamine

• Ethyl Cyanide

• Formaldehyde

• Hydrogen Sulfide

• Methane

• Methyl Mercaptans

• and many more ....

Heritage Lift Station San Jacinto River Authority The Woodlands, Texas 77380

• A very smelly lift station is positioned within a few feet of the property line of a $1M home

• End of pipe systems including chemical drum scrubbers and chemical spray systems did not solve the problem

• Trans-Tech custom designed and installed an air ionizer system with positive pressure air feed on April 2, 2001

• Within minutes the wet well exhaust was clean and odor free. Trans-Tech Energy and Environmental,

MWRD Denver from Pilot to System Design and Installation

• 50F5 modular ionizers will be flange mounted to plenums

• Shown during construction is one (1) of two (2) twenty-four (24) module MWRD plenums

• Total treated volume includes the SPB Basement at 26,800 CFM (45,543 M3/Hr.) and Cake Storage Building at 16,700 CFM (28,373 M3/Hr.)

• MWRD ionization system coming on line September 2003.

CONCLUSIONS

• Bipolar air ionization provides a simple and cost effective odor control solution

• Added value includes corrosion control, health and safety advantages

• Recommendation: Do not allow simplicity of concept to be misinterpreted as lack of need for thoughtful system design and engineering.

• Total costs - capital plus O&M are less than “end of pipe” odor control system alternatives.
