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
Provides clean air in controlled environments housing sensitive electronics. Sits outside the control room and pressurizes the space with clean air. The Tub Scrubber is used in applications where high levels of a single contaminant are present, such as pulp and paper mills.

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 8000 to 20000CFM.





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:

l          Protect personnel and neighbors from exposure to toxic gas

l          Mitigate the entire contents of a fully loaded cylinder in a worst-case release scenario

l          Reduce toxic gas concentrations to less than 5 parts per billion at discharge

l          Exceed the requirements of the Uniform Fire Code and the US EPA Clean Air Act.
