Wet H2S monitor
ATI has developed sensor technology that allows continuous monitoring in scrubbers that employ a wet process using hypochlorite solution to remove H2S from air streams prior to discharge. The Q45S odor monitoring system uses the company’s standard Q45 electronics package in conjunction with a special “Wet H2S” sensor. Measurements may be made either at the inlet to the scrubber system where concentrations can run as high as 200 ppm, or at the outlet where concentrations are ideally down below 0.5 ppm.

Retractable covers
GTI’s retractable, structurally supported cover system consists of a 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 allow a ventilation system to function, yet it can be detached on three sides and retracted to expose the tank contents for inspection or maintenance.

Aerator/mixer
The AIRE-O2 Triton® process aerator/mixer’s oxygenation and mixing improves treatment performance efficiencies making it ideal for odor control in urban areas. Additionally, air is introduced and transferred below the water’s surface thereby eliminating odor problems associated with surface splashing type systems that generate aerosols. The system has a very low dB noise level for urban, populated areas and can also reduce energy consumption. The system an provide oxygen transfer, dispersion and mixing to 33 feet deep that ensures de-stratification and treatment of the entire biomass for aerobic treatment.

Odor control
Officials of ADAPCO Environmental Solutions (AES) have introduced VulchurTM, a new chemical product for the wastewater industry that can control both odor-causing bacteria and corrosion in wastewater systems. The product is designed to remove hydrogen sulfide and mercaptans from wastewater systems. It also reacts to form a corrosion inhibitor for concrete and metal infrastructure and equipment. The product is a direct drop-in replacement for caustic and bleach in wet scrubber systems. It does not increase a system’s pH level, it does not create system solids or build-up and it uses 25% less chemical than other products.

Odor control
Calgon Carbon’s Centaur®HSV is a vapor phase virgin granular activated carbon that has been developed specifically for odor removal from sewage treatment operations. This agglomerated bituminous coal-based product has a high adsorption capacity for H2S - without chemical impregnants - and adsorbs volatile organic compounds (VOCs) in an effective manner. The product, by its catalytic functionality, oxidizes H2S and converts it to water soluble sulfur compounds.

Taste, odor control
Applied Process Technology has announced the availability of HiPOx Plus, a waste-free Advanced Oxidation Process (AOP) that targets taste and odor issues in drinking water. The system combines ozone and hydrogen peroxide to form hydroxyl radicals, aggressive oxidants that react chemically with taste and odor compounds. The process simultaneously removes a wide range of volatile organic compounds (VOCs) and micro-contaminants as well. Its reactor design enables the system to also perform as an effective ozone contactor, or users can alternate between ozone and AOP mode to achieve a variety of application-specific requirements. Multiple reagent injection and reaction points provide improved contaminant destruction and disinfection. In addition to fully engineered packaged treatment systems, the process can also be provided as a stand-alone reactor for integration with other equipment.
