Results of Hydrogen Sulfide
Control Case Study
Radical change in H2S gas.
Peak H2S reduced from 40 PPM to
8 PPM.
Most H2S after treatment was 0
PPM.
Results lasted several days after
test.
Very inexpensive installation.

Where are BOC's added
to the sewer?
BOC's are normally added upstream of
where odor is perceived.

INJECTING BOC'S
Injecting BOC's into the sewer is
simple and inexpensive.
INJECTING BOC's INTO
A GRAVITY SEWER
Using any sewer
manhole . . .
BOC's are dripped
into the gravity sewer

Needed in
some cases
When sprayed on the surface
of the lift station . . .
Grease does not build up on the surface of the wet well.
Odor is reduced at the lift station and downstream.
Lift station walls and equipment are kept clean.
Corrosion is halted.
