Nearly all municipalities suffer with odor problems from manholes. The
main culprit is hydrogen sulfide (H2S), but other malodorous compounds are
present, as well. The problem has not been easy. Treating flow is very
expensive. Systems for treating air usually require electrical power and/or clean
water. Sealing covers moves the problem down the line or through the vents
of neighboring homes and businesses. These complications are all solved
with PEACEMAKER® odor control manhole inserts.
Odor control manhole inserts provide generous venting through PERSNICKETY®
Oxidizing and Polishing media. Oxidation is
accomplished with chlorine dioxide technology. Chlorine dioxide is an
extremely powerful oxidizing agent. For example, one pound is equivalent
in oxidation power to 2.5 pounds chlorine; 3.8 pounds of potassium
permanganate. Because chlorine dioxide reacts selectively and primarily
with only the most offensive odor producing compounds (hydrogen sulfide,
organic sulfurs, organic amines) PERSNICKETY® media will normally
provide a much longer service life than products such as activated carbon.
Unwanted reactions do not occur. Power is not needlessly spent. Chlorine
dioxide remains available and ready on demand.
Polishing is accomplished with Countervailant™ technology.
This technology protects against the escape of malodors which can not be
oxidized or readily oxidized. Countervailant™ technology is a complex and
broadly useful chemistry. It incorporates polymeric adsorption and
electrostatic bonding technologies. Polishing and oxidizing are
accomplished simultaneously. The result is safe, extremely effective,
broad-spectrum malodor control. (Request

Oxidizing and Polishing media, for more detailed information.)
PEACEMAKER® inserts are made to last. They are guaranteed for
three years against manufacturing defects. They will not corrode and
require no maintenance.
