In the modern world of wastewater treatment, control of odors has moved from an afterthought to a primary design consideration for most collection and treatment facilities. As communities and other development increases in the areas surrounding these facilities, the need for odor control systems becomes more important.

Liquid Phase Odor Control
The human nose is extremely sensitive to the presence of a hydrogen sulfide (H2S) and detects is "as the smell of rotten eggs" in concentrations as low as 0.0001 parts per million (ppm).  Typically wastewater related problem odor componds are generated in the liquid phase, during the process of conveying the wastewater from its inception to treatment area.  Inherently odor-causing compounds are violatile and therefore are readily released in the air when given the opportunity, at which point they are referred to as vapor phase odor.

Evoqua Water Technologies is a recognized leader in the development of innovative products for the control of odors in wastewater collection and treatment systems. We offer a full range of treatment options, including our proprietary BIOXIDE®, ODOPHOS® and AQUIT® products, as well as other proven technologies for addressing odor.

There are many treatment technologies and options associated with odor control in the liquid phase.  However, once odors are released into the atmosphere they become vapor phase odors and other control strategies must be considered.

Vapor Phase Odor Control
Vapor phase technologies ventilate/treat the point sources of odor such as wet wells and headworks.  Vapor phase treatment options are primarily focused on the removal of hydrogen sulfide (H2S).  Methods for vapor phase odor control treatment typically include wet chemical scrubbers, biofilters/bioscrubbers, dry chemical scrubbers and activated carbon absorbers.

Among these options, the wet air scrubbing has proven to be one of the most flexible and reliable for vapor-phase wastewater odor control technology.  Click here to learn more about the LO/PRO® Wet Chemical Scrubber from Evoqua.  In addition to treating H2S and organic odors, wet scrubbing has also proven to be effective for ammonia removal.
