SULFILOGGER™ SENSOR SEWER
INSTALLATIONS - TIPS AND TRICKS
When installing the SulfiLogger™ sensor for monitoring hydro-
gen sulfide in sewer networks the following notes may serve as
guidelines for a monitoring campaign:
• Hydrogen Sulfide (H
ditions in the sewer which typically occurs in Force Mains
(pumped sewer lines). The concentration of dissolved H
increases when the residence time and/or temperature of
the wastewater increase. H
pipe, where the wastewater is again in contact with air (head
space). This can be a simple overflow to gravitational sewer
lines, a pump sump for a subsequent Force Mains pump line,
a buffer tank or similar.
• The easiest and recommended way of deploying the Sul-
fiLogger™ sensor for H
to install the sensor with a connecting pipe protecting the
cables. The pipe must be secured to either the sewer wall or
at the top/inlet screen.
• The dissolved H
stretch of an aerated sewer. The exact distance of release
depends on many different parameters such as turbulence
and ventilation conditions, but in general it is advisable to
measure as close to the end-of-pipe of the Force Main as
possible to get a realistic measure of the initial H
tration.
• The SulfiLogger™ S1/X1-1120-5mgLsensor can be mounted
at access points directly on the Force Main. This can either
