Odor Control: Products & Services

Cover system

GTI’s structurally supported cover system consists of a retractable sheet of high strength, UV protected, coated fabric tensioned across a series of low profile aluminum arches which span a tank opening. Applications include odor control, blocking sunlight, temperature control, or preventing debris from entering the tank. The fabric cover is sufficiently air tight to capture odorous gases for removal by a ventilation system, yet it can be detached on three sides and retracted to expose the tank contents for inspection or maintenance. Off-gas removal piping connects directly to the cover system.

Vortex flow insert

The Vortex Flow Insert is designed to help eliminate odorous emissions and minimize corrosion in vertical sewer drops. The patented spiral flow design uses the wastewater’s own flow energy to suppress the turbulence which releases noxious gases.

Odor neutralizer

BioWorld Odor Neutralizer is a water-based concentrated liquid that eliminates offensive odors at their source. All natural, the technology safely neutralizes unpleasant odors, including asphalt, sulfides, mercaptans, paint, urine, skunk and fish. Designed for large scale applications, the product can be added as a concentrate to wastewater, or it can be diluted and fogged into the air with BioWorld drum-mounted foggers and event timers to control odors at wastewater facilities.

Biofiltration odor control

The Mónashell Biofiltration System, available from Bord na Mona, is an alternative to traditional carbon or chemical scrubbing systems and exhibits many advantages over other biofilters. The reuse of waste shells as media maintains a neutral pH, allowing for effective biological treatment of odorous sulfur compounds in wastewater and industrial airstreams without the use of chemicals or nutrient addition.

Wet scrubbers

With over 30 years experience in both industrial and municipal odor control, Ceilcote APC can help utilities select the best scrubbing technology for their facility. Extensive pilot and field test data shows how scrubbers designed with Tellerette® Tower Packing can be operated at increased velocity further reducing both size and cost. The AMCA rated CLUB series FRP fans have been used with wet scrubbing systems, biosystems, and carbon absorption systems. The company’s designs allow for reduced tower diameters for space saving and reduced pumping requirements.

Odor monitoring

OdoWatch® alerts wastewater treatment plant operators of potential odor problems before complaints arise by indicating when process controls are needed to mitigate odor. Sensors in the electronic nose transmit data measured in odor units to a central control computer that uses meteorological data to perform real-time dispersion modeling. The continuous, real-time results display as a color-coded plume overlaid on a map of the site. Alarms notify operators when preprogrammed thresholds are crossed.

H₂S monitoring

High hydrogen sulfide levels can now be continuously monitored and reported with Arizona Instrument’s new Jerome 651 monitoring system. The 631-X hydrogen sulfide analyzer can analyzes H₂S levels as low as 0.003 ppb and as high as 50 ppm. The analyzer is housed in a weatherproof, temperature-controlled box that can be mounted to a building or post depending on the location. For further flexibility, the box also contains a control panel for on-site programming and a 900 MHz radio for remote programming and data downloading.
