Sewer Odor Problems
Sewer Odor Problems
(OP)
I am working on a project to reduce odor for a sewer system. In the sewer system there are two lift stations with large storage volume and low flows. Have any of you ever filled in a portion of the wetwell with concrete blocks or concrete to get the pumps to cycle more often and keep the sewage moving? There are odor problems at these stations and they pump directly to the sewer plant and they have odor problems there also. The odor problems occur around 9 pm and 7 am. The lift stations were designed for future growth that has not happened. They are set up to chemically treat for odor but I am trying to help optimize the stations so they can reduce the amount of chemicals.

There is a vortex that can be inserted to reduce odors.
You can also recycle the flow through a venturi to aerate the contents.

Sometimes, if you are repumping through multiple lift stations, the odor is inevitable.
Odor scrubbers are also available.

also, make sure the trunk sewer is not surcharged and anaerobic. a long sewer which is flowing full can also be problematic.

If your hold time is several hours, it's going to stink no matter what you do for odor control.

The question is when will the lift station capacity be increased and you would need to remove the concrete.

Boifilters can also be a good option. The only weak point is the installation, as it requires a vast land site to set it up.
