Pump and mixer team to treat wastewater - Case Study

Problem
Serving 11,000 residents, the Stafford (Conn.) Water Pollution Control Facility needed an upgrade.
Solution
To improve maintenance and equipment service life, plant personnel installed six 1.8 hp Landia mixers in the anoxic tanks as part of a new activated sludge process. Three 2.4 hp Landia axial flow pumps were added to the aeration basins to return nitrified mixed liquor to the anoxic tanks for denitrification. “Landia sent one of their skilled engineers to show our maintenance staff how to look after the pumps and mixers, which means we provide a better service to the people of Stafford,” says Rick Hartenstein, chief operator.
Result
“We’ve become more efficient, had no downtime, saved money and had no hassle,” says Hartenstein.
