| AIR FILTERS FOR WATER-WASTEWATER APPLICATIONS |
| Odor Scrubbers Purafil ESD systems are available in a variety of sizes and configurations according to meet the unique requirements of each application. When building your system, we consider airflow requirements, desired media service life, space availability, and types and concentrations of odors present. |
 |
Drum Scrubber Offers quiet control of odors at pump stations and in residential communities. Odors are drawn upwards through multiple layers of Purafil ESD media. System is weatherproof and requires little maintenance. Sized for airflows from 0 to 1,000 cfm. |
 |
Tub Scrubber Mitigates high contaminant loads at small headworks, large pump stations, in screening rooms, and at the discharge of biofilters. Features a 3 ft (0.9 m) media bed for increased residence time and the highest filtration efficiency. Sized for airflows from 500 to 6,000 cfm. |
 |
Deep Bed Scrubber Idea for mitigating high loads of multiple contaminant challenges. Horizontal bulk-fill system features up to four media stages. Use at small headworks, large pump stations, in screening rooms, and at the discharge of biofilters. Sized for airflows from 500 to 8,000 cfm. |
 |
MOLE Manhole Scrubber Offers complete control of street-level sewer odors. Odors enter the MOLE and flow upwards through 2 passes of Purafil ESD Odormix SP media. Scrubber collar fits any manhole. |
 |
Vessel Scrubber Designed to mitigate high loads at large headworks, full treatment plants, and large digesters. Sized for airflows from 8,000 to 20,000 cfm. |
| Emergency Gas Scrubbing | |
 |
The Purafil ESD Emergency Gas Scrubber (EGS) prevents toxic chlorine or sulfur dioxide gas releases due to a failure in the storage cylinder or system by providing immediate on-line removal of leaking gas from a room or building. The EGS is designed to achieve the following:
• Protect personnel and neighbors from exposure to toxic gas • Mitigate the entire contents of a fully loaded cylinder in a worst-case release scenario • Reduce toxic gas concentrations to less than 5 parts per billion at discharge • Exceed the requirements of the Uniform Fire Code and the US EPA Clean Air Act |
