They are simple to install, operate and maintain and require no nozzle maintenance, water, mixing or dilution. The technology uses a blend of natural ingredients to eliminate industrial odors without chemicals or masking fragrances. A programmable logic controller-based touch screen lets users set auto sequence startup, see real-time airflow rates, and control liquid flow. An alarm panel alerts users to issues such as low fluid and pressure levels. Options include a wind direction optimizer, remote access and control options, freeze protection for outdoor installations, and alternate voltage. 800/662-6367; www.omi-industries.com.

  Fixed-Film Aerator

The Bio-Wheel fixed-film aerator from H2O Innovation is an alternative to blowers for activated sludge processes. Air is trapped within the wheel plates and slowly released as the wheel turns. The wheel also provides surface area for fixed-film growth to promote the proliferation of high SRT bacteria on the film. The result is a low-energy, versatile integrated fixed-film/activated sludge (IFAS) process that can be used for greenfield or retrofit applications. The suspended growth allows operational flexibility through the adjustment of mixed liquor suspended solids concentrations, while fixed film protects the biomass from shock loads and facilitates removal of difficult-to-degrade compounds while reducing sludge production. 888/688-0170; www.h2oinnovation.com.

  Bagging system

The Longofill continuous bag system by Paxxo can connect to the discharge point of machines used to move, dewater or compact screenings and grit, which are then deposited in a continuous bag for odor containment and spillage control. The cassette is easy to seal, and the material and odors are trapped inside, reducing environmental and health issues and curtailing development of bacteria and fungus spores. 770/502-0055; www.paxxo.com.
