Yep, we're back at it, with another tour of another waste water treatment plant. This time, we headed up to Kokomo to take a look at their facility.
The City of Kokomo, using grant funds from our office, installed variable frequently drives (VFDs) on their existing 600hp blowers. These blowers provide oxygen to their single stage nitrification activated sludge system. Dissolved oxygen meters were installed in the sludge system to monitor oxygen levels, which are used to control the output of the blowers via the VFDs. (It's a mouthful, we know!)
Bottom line is, these actions help save quite a bit of energy and reduce the demand charges. Total savings are estimated at a whopping $115,000 annually!
The City of Kokomo received an Energy Efficiency for Wastewater Treatment (EEWT) grant. This program was funded through the U.S. Department of Energy's State Energy Program (SEP), administered by the Indiana Office of Energy Development (OED).
