Air Filters for Waste Water Applications
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.
Deep Bed Scrubber
Sits outside the protected space and provide
clean pressurization air to rooms equipped with electronic process control systems. The Deep Bed Scrubber offers up to 4 media
beds for control of multiple contaminants in process industries.
MOLE
Manhole Scrubber
Offers complete control of street-level
sewer odors. The collar of the scrubber rests just below the manhole cover. Odors enter the MOLE through the bottom of the
unit and flow upwards through 2 passes of Purafil Odormix SP media, where they are absorbed and chemically converted
to non-organic salts. This is a passive system and does not change the integrity of the manhole.
Vessel Scrubber
Designed to mitigate high loads at large headworks, full treatment plants and
large digesters. The VS is sized for airflows from 8000 to 20000CFM and is available in single or dual media bed designs.
In single bed designs, odors are drawn into the inlet plenum and through the media bed where contaminants are chemically removed.
Dual bed scrubbers feature a split media bed, ideal for higher airflow applications. Treated air is discharged to the atmosphere
through vertical stacks. Typical system utilizes Odorcarb Ultra with Odormix SP as a polishing media.
Emergency Gas Scrubber
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 ppb at discharge
Exceed the requirements of the Unifor Fire Code and US EPA Clean Air Act
