John Stodola, SEH engineer in their waste water department, met with the council Wednesday night to explain the wind powered processor/mixer. ďWe have looked at a number of options this past year and feel the wind processor/ mixer will help solve the odor problem,Ē Stodola told the council.
Stodola and Ron Mergen, Paynesville public works director, visited West Fargo and Hillsboro, N.D. and Ortonville to see the processor/mixer in operation. ďWe received good reports from all three city department heads concerning their units,Ē Stodola added.
The units would float on the surface of the lagoons and the wind powered processor/mixer drives the circulation paddles to circulate the water from the top of the ponds with the water at the bottom. Stodola said the units would not erode the bottom of the ponds.
Stodola recommended the city purchase five wind operated units and five motorized units to ensure there would always be water circulating.
ďThe units can also be used to reduce the BOD (solid) levels in the lagoon ponds but we will be using them strictly for odor control,Ē Stodola added.
Mergen explained the wind processor/ mixers would reduce the electrical demand at the pretreatment pond and in the long run save the city money.
ďThe units at Ortonville were strictly wind operated. They were very pleased with their operation,Ē Stodola said. ďHowever, we canít always count on the wind blowing here at Paynesville like Ortonville.Ē
A rough estimate for the 10 units is $225,000. Approximately 80 percent of that cost will be covered by AMPI and Master Mark.
Mergen said the aeration units would be funded through the sewer capital improvement fund over a 10-year period at seven percent interest. The units have a 20-year life expectancy. City employees would assemble and install the units on the ponds this winter.
The council approve pursuing the agreement with AMPI and Master Mark and preparation of construction costs estimates for the proposed circulation system.
