SETAUKET, N.Y., Aug. 20,
2024 /PRNewswire-PRWeb/ -- The final commissioning of
the municipal wastewater treatment plant in Melrose, Minnesota, is slated for August 2024. The US$ 9
million expansion and upgrade project delivered improved
plant efficiency and treatment capacity to better meet expected
population growth and industry expansion. PENETRON ADMIX SB, a
crystalline concrete waterproofing admixture, was specified for
durability and to extend the service life of the new treatment
plant.
PENETRON ADMIX SB was chosen over a number
of competitive admixtures under review as the best product to
enhance concrete impermeability and extend the service life of the
expanded Melrose facility.
Situated on the banks of the Sauk River, and surrounded by the
Big and Little Birch Lakes, Lake Sylvia, and even more lakes beyond
– a landscape typical of Minnesota
– Melrose is a city of around
4,000 people on the I-94 highway corridor in the center of the
state. Incorporated in the late 19th century once the railroad boom
reached the area, the city today has a vibrant downtown, a K-12
public school system (and private schools), a modern hospital and
medical center, and even a historical society.
The town continues to grow and prosper, which has recently begun
to strain municipal infrastructure. Residential waste and output
from three local industrial plants make up about 80% of the raw
wastewater coming into the Melrose
wastewater treatment plant. Originally commissioned in 1963, the
plant is a three-million gallon a day (MGD) class "A" treatment
facility which has since undergone several upgrades and capacity
expansions, including a series of lift stations and wastewater
lines to convey the wastewater to the plant for treatment.
"Recent inspections revealed substantial concrete deterioration
of key concrete structures at the Melrose plant," noted Christopher Chen, Director of The Penetron
Group. "To meet the increase in demand for treatment capacity due
to the expected growth in population and increased capacity needs
for the local industry, an expansion of the plant's treatment
capacity was needed."
Improving the corrosion resistance of concrete structures in
wastewater treatment plants depends primarily on optimal protection
of the imbedded steel reinforcement. The project engineers at Short
Elliot Hendrickson (SEH) underlined the importance of a robust
waterproofing solution to protect the plant's concrete structures
from corrosion, chemical attack, and permanent exposure to the
aggressive environment of the effluent.
The new upgrades to the wastewater treatment plant include a new
headworks building (new pumps and screens), both new and
refurbished clarifiers, new splitter structures, and updated
metering equipment. The resulting gain in efficiency provided the
Melrose plant with an additional
500,000 gallons per day of treatment capacity.
Worms Lumber & Ready Mix, the ready-mix concrete supplier,
added PENETRON ADMIX SB to the concrete mix for the facility's new
concrete structures.
"PENETRON ADMIX SB was chosen over a number of competitive
admixtures under review as the best product to enhance concrete
impermeability and extend the service life of the expanded
Melrose facility," adds
Christopher Chen. "The ease of
dosing with soluble bags and technical assistance throughout the
project also helped tip the decision to Penetron."
