H2S monitor
ATI’s Q45S odor monitoring system uses a special “Wet” H2S gas sensor in conjunction with a monitor that displays H2S on a large LCD display. The sensor is specifically designed to measure gas in a 100% moisture saturated atmosphere. The monitor also provides 2-alarm relays along with an analog 4-20 mA signal for remote data transmission. An optional sensor air purge system can be provided to remove accumulated water droplets from the sensor membrane, if needed.

Odor control
The AerScrubber™ provides a new approach to odor abatement through Aerisa’s proprietary WaveFour™ technology. Based on cold plasma technology, the system decomposes H2S and other VOCs into their harmless components, greatly reducing odor emissions and producing a clean working environment for site staff. The system uses no water or hazardous chemicals and has no moving parts other than a variable speed fan. It uses electricity to produce a measurable and controllable quantity of negative and positive oxygen ions.

Odor control system
Calgon Carbon Corporation has introduced its new Mini Phoenix® Plus odor control system. The system combines a 1st stage carbon unit with the company’s Phoenix® technology. The 1st stage carbon unit uses coconut or reactivated carbon for reduced sulfur compounds (RSC) and organics to minimize operating costs. The Phoenix® radial flow canisters coupled with the newly designed segmented reactor combine to produce a complete system that continuously removes RSC, organics, and up to 50 ppm of H2S with 99% average efficiency.

Odor monitoring
N.A. Water Systems offers OdoWatch®, an automated electronic-nose-based wireless odor monitoring system. The electronic nose (pictured) transmits data to a central control unit that uses meteorological data to perform real-time dispersion modeling. The rsesults are displayed as a color-coded plume overlaid on a map of a site to alert operators of potential odor problems before complaints arise. This technology is ideal for wastewater treatment plants, composting sites, or any industrial facility with the potential to emit odor.

Gas collection cover
Gas collection floating covers collect methane gas from anaerobic process ponds, which can then be used to generate heat and/or electricity, or flared for carbon credits and/or odor control. Layfield has developed a new prefabricated gas collection cover that can be easily retrofitted to industrial, municipal, and agricultural ponds. The new cover uses a tough, fabric-supported, Enviro Liner 8000 with excellent longevity and flexibility.

Odor control
Process Solutions Inc. has introduced a new odor control technology that not only eliminates odors but also neutralizes pH corrosion, kills biofilm and helps break down grease in pump stations. The new Vapex unit is designed to eliminate odors and stop corrosion in any odorous space by using air, water and power to generate a Hydroxyl ion fog that is injected into the odorous space. No chemicals are purchased, handled or stored.

Venturi injectors
Neighbors near a wastewater treatment plant in Roseville, CA., raised concerned about odors. In an effort to reduce odors at the plant, modification of the mixing system was made by incorporating Mazzei Injector High Efficiency Venturi Injectors for introduction of air. The piping from the circulating pumps was redirected to a manifold incorporating four Mazzei 6094 stainless steel venturi injectors. The discharge of this manifold was directed back into the existing piping to the in-tank nozzles.
