Met-Pro Environmental Air Solutions' Bio-sumpVENT® is a lightweight, modular bio-oxidation system designed to meet the demands for odor control at lift stations, sewer vents, and other small contained processes. The exterior is fiberglass reinforced plastic (FRP) with a sealed lid that houses an internal framework to support patented BioAIRSpheres organic media for the adsorption and digestion of odorous compounds. The system can handle H2S and other odor compounds in airflows up to 200 cfm.

Kruger, a Veolia Water Solutions & Technologies company, has introduced the new OdoWatch 3.0 system. This is an enhancement to the OdoWatch® real-time odor monitoring system which helps wastewater treatment plants stay on top of nuisance odors, preventing odors before they become a problem to the surrounding areas. New Aermod modeling follows the odor plume over terrain, allowing plants to track odors more efficiently.

Scrubber monitoring system
The MSA scrubber monitoring system offers both in-situ-type sensors for large diameter pipes and pre-engineered sample draw systems for higher detection ranges. For use in most wet or dry hydrogen sulfide or chorine scrubber applications, its monitoring range is 0-25 PPM. Advanced features include smart sensors, onboard relays and LEDs, internal power supply option, and true one-person calibration.

Parkson has introduced OHxyPhogg™, an odor removal technology with a patented air-atomizing 3-fluid nozzle. The system combines ozone, water and air, creating 5-micron sized oxidant enriched water particles that disperse and fill partially or fully enclosed spaces such as lift stations, wet wells, holding tanks and headworks. The oxidant fog reacts with H2S and other reduced sulfur compounds, removing the unpleasant odors.

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.

Odor, corrosion control
ECO2 SuperOxygenation technology is an environmentally friendly odor and corrosion control solution that can be applied in force mains or upstream of headworks and primary clarifiers. The system dissolves pure oxygen at >90% absorption efficiency into wastewater under pressure to achieve DO concentrations of 50 to >150 mg/L. It can help eliminate hydrogen sulfide odor and corrosion by dissolving enough oxygen in wastewater to maintain aerobic conditions which prevents the formation of hydrogen sulfide. The system can be added to current facilities in virtually any location or footprint.

OMI Industries has introduced the Ecosorb® Spray Gel - an odor control product designed for topical applications onto solid and semi-solid materials that emit odors. Applications of this new solution include solid waste materials, wastewater sludge, compost materials and remediation soil. Using the same scientific odor control formula found in Ecosorb liquid products, the spray gel applies a thin, semi-liquid gel film onto the surface of the odorous material causing contact between the emitting odors and the product.

Bioscience offers a line of bacterial products to help degrade fats, oils and greases (FOG), enhance settling or reduce the generation of odor-causing sulfides. Bacterial products may also be added to increase the capacity of the biomass to degrade more typical waste streams and reduce effluent ammonia, BOD and suspended solids. The products feature specially designed mixtures of pre-adapted bacterial strains, growth enhancers and complimentary ingredients, which help eliminate the adaptation phase and allow the plant to adjust to new conditions and overloads faster.

Scrubber odor monitoring
Odor control in wastewater treatment plants and sewage collection systems often require the use of scrubber systems. Many scrubbers employ a wet process to remove the H2S from the air stream prior to discharge. Monitoring in this environment has often been a problem for standard gas sensors but ATI has recently developed a sensor specifically for this wet process. The Model Q45S odor monitoring system uses a specially designed "Wet H2S sensor" and can measure concentrations up to 200 ppm or very low levels down to 0.5 ppm. The Q45S provides a large LCD display showing concentration with a second display line to show other status information.
