Odour Control Systems
Our odour control systems offer flexibility in project design, installation and service intervals like never before for elimination of sewer and other gases.
Reduce Maintenance & Service Costs with our Odour Control Systems
Realising that most projects require their own unique solution, our odour control systems are based on a common structural arrangement which then branches into a matrix of different diameters, heights & configurations, passive or active flow.
In addition, there are standard sized models available for quick selection and early delivery.
The Purafil media used in these dry scrubbers targets H2S aggressively and has an extremely high capacity for removal.
Manhole Scrubber (MOLE)
The MOLE™ Manhole Scrubber is a passive odour control system for street-level sewer manholes. It is designed to eliminate noxious sewer odours on busy streets filled with pedestrians.
The Purafil MOLE™ Manhole Scrubber effectively removes odours emanating from street-level sewer manholes. The collar of the scrubber rests just below the manhole cover. Odours enter the MOLE™ through the bottom of the unit and flow upwards through two passes of Odourmix™ SP media, where they are absorbed and chemically converted to non-organic salts.
Construction
The MOLE™ is constructed of stainless steel to ensure a long service life. Housed within the unit are two MediaSAKs containing Odourmix™ SP media. The unique design of the MediaSAK prevents air bypass and ensures a high removal efficiency.
Maximum Airflow
The MOLE™ passively removes odours at airflow rates up to 50 cfm. The bottom of the unit is 100% open for maximum allowable airflow through the media bed.
Easy Media Replacement
The MOLE™’s Odourmix SP media is contained in two, MediaSAKs, which are layered vertically within the unit. MediaSAKs are factory-filled, so installation and replacement is an in-and-out job.
High Efficiency
The MediaSAK holds one cubic foot of dryscrubbing media. The unique design of the MediaSAK allows for easy replacement while preventing air bypass.
Air Filtration Media
At the heart of Purafil’s high-efficiency odour control systems are dry chemical, air filtration media. While hydrogen sulfide is the primary culprit in sewer applications, sulfur dioxide, mercaptans, aldehydes, and volatile organic compounds (VOCs) are also responsible for odour complaints. The unit’s Odourmix™ SP media effectively removes all sewer odours. Most importantly, Odourmix™ SP can accommodate fluctuating odour concentrations and airflows, as well as continuous air streams. Odourmix™ SP media are UL classified, non-toxic, nonhazardous and landfill disposable.
