County Drastically Cuts Costs With DIMMINUTOR®

Jane Cooper

Fairfield Wastewater Treatment Plant in Butler County, Ohio was having a lot of trouble with their grinders. The plant serves over 42,500 domestic customers, a number of commercial and industrial institutions as well as Mercy Hospital of Fairfield. They treat about five million gallons of wastewater collected in over 175 miles of sewer pipe each day.

The brand of grinders they were using was extremely costly to maintain. They had two – one in each of their wet wells. Each year, one of the units would come out for a full rebuild due to the cutters’ complete deterioration. This was costing them about $25,000 a year in rebuild costs.

“It was ridiculously expensive,” Brad Abner, Chief Operator at Fairfield WWTP, said. “There was no way we could keep using something with such high maintenance costs.”

After some market research, the plant decided to install a Franklin Miller DIMMINUTOR® Wastewater Grinder to replace their current machine. Almost immediately, they found the DIMMINUTOR to be more reliable and easier to maintain than their old grinders ever was.

“They are running wonderfully,” Abner said. “Even if we had to maintain the DIMMINUTOR on the same schedule as our old machines, it would still be half the price.”

The DIMMINUTOR is an open-channel comminutor that provides automatic screening and grinding of liquid-borne solids with a straight through design. This unit reduces plastics, wood, vegetable matter, disposables, and other oversized items to a fine particulate. The DIMMINUTOR’S unique features, heavy precision construction, dependable operation and simplified maintenance have earned it a solid reputation amongst operators and specifying engineers worldwide. The DIMMINUTOR is designed for reliable operation and easy maintenance. For example, with its cantilevered design, the DIMMINUTOR needs no seals or bearings near the gritty channel floor. The unit’s screen is stationary so it never wears against bottom grit. Each cutter is interchangeable and cutters can be removed or adjusted independently. The unit’s seals and bearings are immersed in an oil bath for long life and low maintenance.
