8Results 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.

10Inside a Gravity Sewer Pipe
Pipe
Airspace
Sewer Water
11Inside a Gravity Sewer Pipe
Bacteria form inside the pipe
12Inside a Gravity Sewer Pipe
A Protective slime builds up over the bacteria
Bacteria form inside the pipe
Oxygen is limited
13Inside a Gravity Sewer Pipe
The bacteria become predominately Anaerobic
The slime prevents oxygen from getting to the
bacteria
14Inside a Gravity Sewer Pipe
At the same time . . . Oxygen in the sewer water
is depleted
The entire sewer becomes anaerobic and compounds
are reduced. . . forming odors
Sulfates

H2S Gas forms
18Inside a Gravity Sewer Pipe
H2S gas is also very corrosive . . . .
Pipes are destroyed
H2S Gas forms
19Inside a Gravity Sewer Pipe
Slime and grease continue to build on the pipe
Flow is reduced
Slime builds
20Treated With BOC's
21Treated With BOC's
The protective slime layer is reduced
22Treated With BOC's
Exposing anaerobic bacteria to oxygen
The protective slime layer is reduced
Microbubbles add oxygen to the sewer
23Treated With BOC's
Odors are prevented from forming in aerobic
conditions
The entire sewer becomes more aerobic . . .
Corrosion stops
24Treated With BOC's
Reducing the possibility of sudden odor blooms
With continued use the pipe becomes cleaner . . .
Preventing corrosion
Increasing flow
25Treated With BOC's
The entire process happens slowly, naturally
But lasts for several days after
stopping Injection
26Where are BOC's added to the sewer?
BOC's are normally added upstream of where odor
is perceived.

39INJECTING BOC'S
Injecting BOC's into the sewer is simple and
inexpensive.
40INJECTING BOC's INTO A GRAVITY SEWER
BOC's are dripped into the gravity sewer
Using any sewer manhole . . .

42When 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.
Flow increases
