How to Best Address Sewer Odor Control

It is important for the maintenance of sewer odor control at wastewater treatment plants, landfills, and other locations. Even on a cold, windless day, there can still be an odor in these areas. This can cause problems for workers as well as the communities surrounding them.

People can now easily express their concerns online, thanks to social media, and unwanted attention can lead to penalties and fines. A wastewater treatment plant's sewer odor control

system is more important now than ever. It is important to implement a solid sewer odor control system if a facility doesn't already have one.


Identify the Sources

To effectively address sewer odor control

and treat odors emanating from a wastewater facility, it is crucial to identify their source. There are likely multiple sources of odor that could need sewer odor control maintenance. It is possible that the odor can be controlled by a single system located around the perimeter of the wastewater treatment plant.

Common sources of wastewater odor

The majority of wastewater treatment facilities can dispel odor, which is why sewer odor control is so important. The following areas can also produce the funky smelling hydrogen sulfide and ammonia as well as the necessary sludge handling and primary wastewater treatment.

  • Headworks

  • Clarifiers

  • Sedimentation basins

  • Lift stations

  • Lagoons

  • Biosolids treatment

  • Wastewater septage dumping

Find the Odor Factors & Causes of the Elements

Many characteristics of odor production can be used to determine whether they are detectable and how to approach sewer odor control. When the molecules of a smell are stimulated by the body's olfactory sensor cells, which are responsible for processing the smells, we sense them.

Once we have identified the source of the odor, we can identify the best sewer odor control solution to remove it. It is important that you consider the fact that location and weather conditions can have a significant impact on how wastewater facilities emit odors.

When deciding on the best sewer odor control delivery method, temperature, humidity, wind, and precipitation should all be considered. As an example, let's say a facility is in a hot and humid region (e.g. Florida). Odor problems will be much more severe than those at a wastewater treatment plant in Washington.

A facility that produces hydrogen sulfide and ammonia odors in hot and humid conditions is well-suited for this environment. Even worse, volatile organic compound in a facility begins to come off, creating more odor and requiring an even bigger need for sewer odor control.

Select an Sewer Odor Control Partner

With all these considerations, it is best to work with a sewer odor control partner to find the best odor management solution for your wastewater treatment facility. Specialized companies in sewer odor control know how to access the facility, determine the source of the odor, and can factor in weather and environmental conditions before recommending the best course of action.

Each company's approach to this may differ. Some sewer odor control companies will send a team to inspect the wastewater treatment plant on-site. This is the best way for the site to be identified as to what causes the odor. Additionally, it helps to identify the right plant-based solution and the type of equipment required for those particular solutions.

A sewer odor control partner like In-Pipe Technology will not only help you identify the solution for the odors, but will also be your go-to resource for all future needs.

Choose the Optimal Odor Control Solutions

Other sewer odor control parters use natural, plant-based formulas to neutralize odor molecules rather than masking them. These methods can be used to safely and completely control odor emissions from wastewater treatment processes.

These plant-based solutions instantly bond with odor molecules when they are dispersed in the air. The plant-based molecules become bonded and absorb odor molecules. This is similar to water droplets being pulled into a sponge.

The process of odor neutralization occurs when the odor molecules are completely enveloped by these plant-based molecules using a combination water solubility principles as well as natural plant oil reaction.

Plant-based solutions offer flexibility in delivery. This is crucial because there is no one-size fits all solution to odor control. What works for one facility might not work for another. Some customers may require more than one system to combat odors at their facility, such as spray gel, vaporization, and atomization.

Here are some examples of how different sewer odor control solutions might be applied at different locations in wastewater treatment facilities.

Primary Treatment & Headworks

Hydrogen sulfur odor is an issue in wastewater treatment plants. This issue can be solved by fan or vapor systems installed at digesters and bar screens. Sometimes, the product can also be diluted with water from plants to make a more economical solution.

Basins for Activated Biosolids

Basins used to activated biosolids can be large and often uncovered. These basins allow smells to freely drift into surrounding areas. These previously uninhibited orders can be neutralized naturally with custom biochemical delivery systems. Sewer odor control solutions can easily be dispersed using either low-pressure or high-pressure systems.
