/PRNewswire-PRWeb/ -- Construction work at the Orchard Island
sanitation sewer system in Bellefontaine, Ohio, was completed by October 2023. The repair and upgrade project
helped the Logan County Water Pollution Control District meet the
Compliance Schedule issued by the Ohio EPA. Penetron's
antimicrobial concrete admixture provided the crucial permanent
concrete protection for the new sanitary sewer lines, lift
stations, and a pressure sewer from microbially-induced corrosion,
which can rapidly compromise and disable concrete structures.
Thanks to an effective antimicrobial
technology and attractive cost, Penetron's antimicrobial concrete
admixture will provide the long-term protection from MIC that the
Orchard Island project required.
The Logan County Water Pollution Control District provides
service to the residents of the Orchard Island and Wolfe Island
areas in central western Ohio.
"By 2020, the repair of the Orchard Island infrastructure became
urgent. The District's sanitary sewers were at the end of their
service life and had begun to fail. This allowed significant
amounts of clean water to enter the system through joints, cracks
sump pump connections, and other sources, bypassing the wastewater
treatment plant," explains Christopher
Chen, Director of The Penetron Group. "As a result, the Ohio
EPA issued a Compliance Schedule to the District to remove clean
water from the sanitary sewer system and prevent any further
sanitary sewer overflows."
However, before construction could begin, the Orchard Island
project engineer at Choice One Engineering needed a proven and
durable solution to avoid the threat of microbially induced
corrosion (MIC) to both the new and repaired concrete structures
that were part of the project.
For the construction industry, MIC is a serious challenge that
causes billions of dollars in damage to wastewater and
sewage-related concrete structures every year. The root cause is
the thiobacillus bacteria found in sewage and septic environments,
which converts hydrogen sulfide gas (H2S) into biogenic sulfuric
acid (H2SO4). The presence of sulfuric acid on concrete surfaces
can unleash highly localized and rapid corrosion processes that eat
away the cement paste of the concrete matrix. This, in turn, can
quickly expose the embedded reinforcement steel of underground
concrete sewage systems to water, oxygen, CO2, and chlorides –
resulting in catastrophic corrosion-related failures in the
concrete.
"Initially, a competitive antimicrobial product was specified
for the Orchard Island project. After Choice One Engineering saw
how our antimicrobial concrete admixture had performed in many
similar projects across the country, Penetron won the job," says
Christopher Chen.
Penetron's antimicrobial admixture prevents microbial-induced
corrosion (MIC) by using an electro-physical mechanism to destroy
the cell walls of the thiobacillus bacteria, also known as
acid-producing bacteria. Eliminating the bacterial growth on and in
concrete consistently stops the formation of biogenic sulfuric
acid, avoiding the damage caused by MIC.
Bluffton Precast added Penetron's antimicrobial admixture to the
concrete mix for all precast elements. Identical to the well-known
PENETRON ADMIX, a crystalline concrete waterproofing admixture, the
antimicrobial properties of the admixture are permanent; it becomes
part of the concrete matrix and is leach resistant, even repeated
contact with bacteria does not lessen the effectiveness of the
admixture.
The ensuing renovation work for Orchard Island replaced all main
sewer lines (including residential connections in the
rights-of-way), added new pump stations and a pressure sewer
connected to the Logan County Water Pollution Control District's
sanitary sewer system.
"Thanks to an effective antimicrobial technology and attractive
cost, Penetron's antimicrobial concrete admixture will provide the
long-term protection from MIC that the Orchard Island project
required," adds Christopher Chen.
"The enhanced durability will minimize the need for future repairs
of the treated concrete structures."
