Biotrickling filter
New biotrickling filter technology from BioAir Solutions can remove both organic and inorganic odorous compounds from municipal wastewater treatment plant airstreams. The company's EcoFilter™ line of products – which use its proprietary EcoBase™ synthetic media – treats the same amount of air as competing technologies, in a unit one-third the size and in one-third the residence time. The media can remove more than 99.9 percent of hydrogen sulfide odors, including more than 99 percent of all odors.

Aerator/mixer
Aeration Industries' surface-mounted Aire-O2 Triton® aerator can reduce odor problems by driving fine-bubble aeration and horizontal mixing to depths of 33 feet. This keeps solids in suspension and ensures total biological treatment and no dead spots. There are no aerosols and very quiet operation making the aerators community friendly. The system's dual-function capability allows for controlled aeration and/or mixing.

Hydroxyl ion fogging
Parkson Corp. and Vapex Environmental Technologies have formed a partnership to market Vapex odor control technology in North American. The company's O-Mega hydroxyl ion fogging technology eliminates odors and reduces pH corrosion found throughout wastewater systems. Instead of more traditional technologies that extract and scrub odors, the O-Mega oxidizes the odorous space itself, eradicating the odors without the expense of moving high volumes of air. The two companies will also offer the Sentinel scrubber control system, which monitors the internal gas passing through a scrubber and reduces scrubber chemicals by up to 60%.

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

Odor monitoring
OdoWatch® provides continuous, real-time results of odor measurements from wastewater treatment, composting, or industrial operations. The electronic nose (e-nose) is calibrated to "smell" and quantify site odors in odor units (d/t). The system is comprised of one or more e-noses, a weather tower, a wireless communications system, and a computer preconfigured with OdoWatch software. The e-noses are positioned near the odor sources of the site. Using weather data, the system performs real-time dispersion modeling using AERMOD and displays the results as a color-coded plume on an aerial view of the site. The system alerts operators when odors begin to reach threshold values, enabling them to respond before an odor problem occurs.

Biological odor control
The ZABOCS™ process, available from Siemens, is a non-hazardous biological treatment system that combines gas adsorption with biological oxidation to capture and then eliminate organic and inorganic odors. This two-stage process combines biofiltration with an integral activated carbon media polishing stage. The system provides immediate odor control with zero acclimation period. It is available in nine models that range in capacity from 350 to 5,000 cfm. Manufactured from glass-reinforced plastic, the skid-mounted system is factory-assembled, charged with media and ready for site installation. Designed for unattended, automatic operation, the systems are ideal for remote wells, pumping stations and sewage collection systems.

Biofilters
Biorem has launched its SK Series of skid mounted, two-stage biofilters. The systems come in two sizes, one to treat up to 250 cfm of contaminated air and one to treat up to 450 cfm. The systems benefit from the use of the company's permanent XLD media, which helped reduce their footprint. The pre-assembled units are housed on a self-contained skid and shipped complete to site for rapid installation.
