How do you control the smell in wastewater treatment?
Ensuring dissolved oxygen is reaching the very bottom of an aeration basin is key to avoiding odour as this is where the odour-causing anaerobic digestion occurs. By circulating the wastewater effectively, you can create nearly equal dissolved oxygen throughout. This in turn will promote odour-free aerobic digestion..
How do you reduce the smell of wastewater?

How does odor control system work?
This odor control method treats the air to remove odorous gasses. Adsorption in wastewater odor control systems primarily uses activated carbon to act as the media. This is done by forcing the odorous air displaced from the wet well across a bed of activated carbon, which produces clean air..

How odor can be controlled in water?
Removing odor from water can be done through treatment in the form of activated carbon or oxidation-reduction. Aeration is also another treatment method which can be used as long as the contaminants are gas sources, such as hydrogen sulfide..
What is odor control in wastewater treatment?
Liquid Phase Odor Control A liquid phase dosing program can be used to prevent odorous compounds from forming in wastewater. Chemicals, such as Bioxide\xae Solution are added directly into the wastewater stream along the wastewater pipeline..

One stage carbon filtration
Single-stage chemical scrubbing
Dual systems
Chemical scrubbing: Absorb the odour-causing pollutant into the scrubbing medium. Ozone treatment: Ozone reacts with odour-causing particles, chemically changing emissions. Photoionisation: UV light in a controlled environment causes chemical reactions, reducing odours.
Ensuring dissolved oxygen is reaching the very bottom of an aeration basin is key to avoiding odour as this is where the odour-causing anaerobic digestion occurs. By circulating the wastewater effectively, you can create nearly equal dissolved oxygen throughout. This in turn will promote odour-free aerobic digestion.
A liquid phase dosing program can be used to prevent odorous compounds from forming in wastewater. Chemicals, such as Bioxide® Solution are added directly into the wastewater stream along the wastewater pipeline. The dosing can be monitored remotely and adjusted automatically throughout the day relative to flow rates.
Evoqua offers a wide range of equipment and services to effectively control odors in your wastewater system. Two-stage odor control system for complete odor
Wastewater odor control is the process by which the malodors in sewage are either prevented from being formed in the first place with liquid phase treatment — treatment within the wastewater — or by capturing and/or treating the vapor coming off the treatment process — vapor phase treatment.
Can wastewater odors be controlled?
The good news is that all of these wastewater odors can be controlled with the right treatment solution
Evoqua offers a wide range of equipment and services to effectively control odors in your wastewater system
As a result, you can eliminate odor complaints, reduce corrosion and protect public health
What is liquid stream odor control?
Liquid Stream Fundamentals: Odor Management and Control Odor control is an operational strategy utilized at water resource recovery facilities (WRRFs) and in the wastewater collection system to mitigate nuisance odors in the surrounding communities
Why is odor control important?
Depending on the design criteria, odor control can assist with worker health and safety considerations, as well as decrease the production of corrosive conditions that impact the useful life of treatment system infrastructure
Odors are generated from every phase of wastewater management including collection, treatment, and disposal
Odor control is an operational strategy utilized at water resource recovery facilities (WRRFs) and in the wastewater collection system to mitigate nuisance odors in the surrounding communities.

An odor or odour is caused by one or more volatilized chemical
Volatile chemical compounds perceived by the sense of smell
An odor or odour is caused by one or more volatilized chemical compounds that are generally found in low concentrations that humans and many animals can perceive via their sense of smell. An odor is also called a smell or a scent, which can refer to either an unpleasant or a pleasant odor.
The Point Loma Wastewater Treatment Plant is a primary
Wastewater treatment plant in Point Loma, San Diego County, California
The Point Loma Wastewater Treatment Plant is a primary waste water treatment facility located on the Point Loma Peninsula in San Diego, California. It is a notable facility due to its ability to treat 1 gallon of waste water for 1/3000th of a penny. The process used to treat the waste water has been perfected to treat a large amount of water as inexpensive as possible. This waste water facility is also noted for its high percentage of removal of pollutants while also remaining a primary treatment facility. The solid removal rate is between 88–90% while the BOD removal rate is kept at 60%. This unique process involves adding Hydrogen Peroxide in order to retrieve and recycle the iron salts that are used in treatment, thus enabling major cost savings.
