Biofiltration odor control

Pennwell web 237 300

The Anua Compact Mónashell Biofiltration System is suited for treatment of airflows up to 150 cfm. The system performs across a broad range of odor-producing compounds. With built-in pH control and automatic buffering, no chemicals are required. Water usage is very low, and the water discharged from the system is at a neutral pH. For remote pump stations without a water supply, rainwater or filtration of the raw wastewater can be used.

Telog Instruments has announced the availability of direct interface support for the OdaLog Gas Data Logger, a product of App-Tek International. The interface provides a combined battery powered, wireless monitoring and alarming system for concentrations of hydrogen sulfide, with the construction and dependability required to operate in a sewer environment. The interface brings together the OdaLog Logger and the Telog Ru-33 wireless telemetry unit, combining H2S monitoring with the capability to transmit collected data to the command center for real-time analysis.

Odor, corrosion control

The Vortex Flow Insert from IPEX is designed to eliminate odorous emissions and minimize corrosion in vertical sewer drops. With no moving parts and requiring virtually no maintenance, the inserts have delivered significant cost savings in monthly chemical feed, air-phase treatment and maintenance costs. Their patented spiral flow design uses the wastewater's own flow energy to suppress the turbulence which releases noxious gases.


H2S monitoring

The heart of the Jerome® H2S monitor from Arizona Instrument is the Gold Film Sensing Technology. A thin gold film, in the presence of hydrogen sulfide, undergoes an increase in electrical resistance proportional to the mass of hydrogen sulfide in the sample. When the sample button is pressed, an internal pump pulls ambient air over the gold film sensor for a precise period of time. The gold film sensor on the new Jerome® J605 adsorbs the hydrogen sulfide, and the instrument determines the amount adsorbed, displaying measured concentration of H2S in parts per million (ppm) or parts per billion (ppb) depending on the range in use.

OdoSulf® is a real-time, continuous hydrogen sulfide monitor for the wastewater treatment industry. It provides fence-line monitoring with H2S sensitivity as low as 2 ppb. As a point-source monitor, it measures up to 100 ppm and integrates with OdoWatch®, the system that uses real-time, on-site weather data to give users a graphic plume showing local impact. The sulfNoses are compact, and can be easily repositioned. Archived data can be retrieved with just a click, and real-time alerts are sent by email. OdoSulf has a multi-user, web-based interface, so users can monitor real-time H2S values from anywhere – on a PC, tablet or smart phone.

ECO2 SuperOxygenation technology is a preventative treatment for odor control. By dissolving pure oxygen into a wastewater side stream and pumping it back into the system, aerobic conditions are maintained and H2S formation prevented. The system can save money on alternative, sometimes hazardous chemicals, and eliminates the need for covers and scrubbers.
