The Terminodour odor control system from CSO Technik, distributed in North America by Kusters Water, division of Kusters Zima Corp. (Spartanburg, S.C.), neutralizes odor at its source. Ionized air is pumped into the building, where it reacts and oxidizes odors, while maintaining a healthy work environment for operators. It uses no water, chemical or media.

“Most odor control systems extract and scrub odor from the gas stream. Terminodour generates negatively charged oxygen molecules and delivers them into the source of the odor, be it a building or a tank,” says Colin Froud, CEO, CSO Technik. “The odors are then oxidized by contact with the ionized air.”

Fresh air is drawn by a fan into the Terminodour system via an external louver and filtered to remove particles. The filtered air is passed into the plasma reaction chamber where hydrogen and oxygen molecules are electrically charged in a 5:4 ratio. The resulting ions are distributed throughout the building according to the location and severity of odor emission points.

Odor reductions of 80 to 95 percent can be achieved within a building and up to 99 percent in storage tank and wet well applications.

“Most of our 200-plus installations are in the wastewater sector,” Froud says. Typical applications are headworks, wet wells, pumping stations and EQ basins. “We have also installed systems in sludge treatment centers, although typically we provide combination systems incorporating the Terminodour with scrubbing systems in this type of application for an effective, low-cost solution.

“On a recent project we were able to offer greater than 50 percent reduction against the cost of a chemical scrubber with operational costs about 25 percent of the chemical scrubber system,” Froud says.

The odor control system has a small footprint and requires minimal maintenance. “The improved air quality also results in greatly reduced sulphide-inspired corrosion of concrete and plant control panels,” Froud says.

The system is designed to control hydrogen sulphide, mercaptans, DMS (dimethyl sulfide), DMDS (dimethyl disulfide), amines and other wastewater-related gasses.

The modular unit can be sized to meet plant needs. Quarterly maintenance of the inlet filters and ionizing tubes requires no specialized tools or training. Odor control systems are available for rent or trial usage. 800/264-7005; www.kusterswater.com.
