Wastewater odor control – eliminate odors in wastewater treatment facilities

Novozymes’ approach involves the use of advanced sampling and analytical techniques to identify what odor compounds are present and determine where they are being formed and stripped into the atmosphere.

Odors from a wastewater treatment facility are not only an annoyance for neighbors, but also a safety concern for workers. Objectionable odors continue to rise on the list of major process considerations in industrial and municipal wastewater treatment and collection. While several products and strategies exist for wastewater odor control, bioaugmentation has the unique ability of being able to respond in a dynamic manner.

Novozymes’ approach involves the use of advanced sampling and analytical techniques to identify what odor compounds are present and determine where they are being formed and stripped into the atmosphere. This information is used to develop a biological wastewater odor control program that eliminates existing odors in the wastewater treatment facilities and stops odors from forming in the first place.

As microorganisms degrade odor-causing compounds, odors simply disappear. Novozymes offers several strategies for wastewater odor control.

Novozymes’ OdorCap® 5700 is a microbial product for most wastewater odor control applications. The microorganisms in OdorCap® 5700 biologically oxidize common odor-causing compounds such as hydrogen sulfide (H2S), mercaptans (R-SH), and short-chain volatile fatty acids (VFAs). These microorganisms can use either oxygen or nitrate as an electron acceptor in their metabolic processes.

OdorCap® 5700 – Odor control for sulfur-based odors

Many of the odors are sulfur-based, such as hydrogen sulfide (H2S) and mercaptans. They are detectable at extremely low concentrations and are often caused by nuisance bacteria, which inhibit wastewater odor control, that grow in anaerobic environments. Sulfur-based odors, like many of the issues around wastewater treatment plants, are biological problems that are often best solved with biological solutions purposed at wastewater odor control.

OdorCap® 5700 contains patented biological wastewater odor control technology and can degrade hydrogen sulfide, mercaptans, and volatile fatty acids. A biological wastewater odor control program using OdorCap® 5700 offers superior odor prevention because it works in the same environments where odors are generated. Furthermore, it has no unintended negative impact on the biological treatment system.

OdorCap® 5135 - Odor control

OdorCap® 5135 contains a proprietary odor-binding agent for immediate results plus odor-degrading microorganisms and a biological stimulant for long-lasting odor control. It is the most complete biological odor control solution for a variety of wastewater odors.

OdorCap® 5115 - Odor control with fragrance

OdorCap® 5115 is a biological odor control solution for general wastewater applications and sludges. It contains a high concentration of odor-degrading microorganisms for long-term odor prevention plus fragrance for immediate relief.
