Biofiltration
Anua AiraHybrid-175
The AiraHybrid-175 from Anua is a multistage system that addresses both odor control and noise reduction in a compact, factory-assembled solution. The first stage uses a biological process to remove hydrogen sulfide and other water-soluble odorous compounds with AiraGlass foamed glass media, made from recycled glass. A second-stage activated carbon system removes remaining odors while extending media life and reducing operating costs. Integrated noise-abatement equipment comes standard, and each unit is shop-assembled, tested and delivered with media preloaded for fast installation. 336-547-9338; www.anua-us.com
Evoqua Water Technologies BTF-Bioscrubber
The BTF-Bioscrubber biological odor control system from Evoqua Water Technologies is an advanced, nonhazardous biological air treatment system that integrates equipment, media and the NUCIRC process for optimal performance and flexibility. Utilizing a dual-stage biotrickling filter system, which can be operated in both single- or dual-stage modes, applications have achieved 99.9% hydrogen sulfide removal and up to 97.5% of total odor removal during performance testing. The process skid allows operation in recirculation or once through modes, delivering accelerated acclimation without separate startup equipment. Systems are available in both single- and dual-stage options with single-stage recirculated systems suited for treating raw biosolids odors found in pump stations, headworks and primary sedimentation, while dual-stage systems are better suited to handle entire plant odors. 800-466-7873; www.evoqua.com
Mazzei Injector Pre-Filter Aeration System
The Pre-Filter Aeration System from Mazzei Injector provides in-line oxidation of iron and hydrogen sulfide ahead of media filtration. Ammonia removal can also be achieved. The system pairs a sidestream injection skid with a Pipeline Flash Reactor installed on the mainline. A booster pump circulates water through a venturi injector that draws in atmospheric air, and the air-water mixture is reintroduced into the mainline, through the PFR, to promote mixing and oxygen transfer. The process converts soluble ferrous iron to ferric iron for removal by filtration, oxidizes H₂S to address odor concerns and supports biological activity for the removal of ammonia via nitrification. By improving oxygenation prior to filtration, the system can reduce chlorine demand and support overall treatment efficiency. It accommodates varying flow rates with nearly zero pressure loss. Routine maintenance is limited to the pump. 661-428-1091; www.mazzei.net
Sierra Environmental Technologies ODORGUARD
The ODORGUARD unit from Sierra Environmental Technologies is a high capacity, radial-flow manhole and wet well insert.

The lightweight components and distinctive design allows the unit to be installed by one person in less than 30 minutes. It is constructed of stainless steel and other corrosion-resistant materials to last. A bottom swing-open trap door allows easy media removal, in or out of the manhole. 636-273-5189; www.setodorcontrol.com
Titus Wastewater Solutions TITUS Twister Mixing Aerator
The TITUS Twister Mixing Aerator from Titus Wastewater Solutions provides a chemical-free approach to odor control by combining powerful aeration with mechanical mixing to create aerobic conditions that suppress odor-causing gases while improving wastewater pretreatment performance. Using air-lift technology, membrane diffusion and internal shear blades, the system introduces fine air bubbles that transfer oxygen into the wastewater while continuously mixing and suspending solids. This process helps break down solids, prevent blockages and reduce odor generation without relying on chemical dosing. At a recent installation at an 11 mgd wastewater treatment plant in Texas, the TITUS Twister reduced persistent hydrogen sulfide levels of over 1,000 ppm to approximately 40 ppm within a single day, maintaining those levels afterward. 877-582-9899; www.tituswws.com

The Definitive Deodorant Company Formula 105
Formula 105 from The Definitive Deodorant Company is an aqueous deodorizer designed to neutralize waterborne odors. It accomplishes this by combining with TSS in such a manner as to prevent them from creating odor. To ensure its effectiveness, it must be dispersed throughout the system that is to be deodorized. The beginning usage factor is about one part per 100 parts TSS in the wastewater. Over time it will aid aerobic bacteria in a wastewater system. In addition to neutralizing odor, it reduces solids’ appetite for dissolved oxygen, providing more oxygen for aerobic bacteria. It is nonvolatile, nonhazardous and biodegradable, allowing it to be suitable for land application. 816-221-4007; www.odorless.com
