How the Franklin Miller Dimminutor® Became an Olympic Winner

The Franklin Miller DIMMINUTOR® was selected for the state-of-the-art sewage system infrastructure project built to accommodate the Olympic Winter Games in Sochi, Russia. After an intensive construction project, multiple Model DM36XF DIMMINUTOR® open channel comminutors were employed throughout the new sewage system. Each unit has the capability of 29 million gallons of raw sewage per day.

As part of the preparation for the games, an advanced sewage treatment system in Sochi had to be built. Designed by Olimpstroy, the system is said to meet BREF standards and employ top available technologies including tertiary treatment with microfiltration.

The advanced sewage plant is part of a series of state-of-the-art infrastructure projects that were built in preparation for the games. The extensive construction plan involved building and modernizing the telecommunications, power and transport infrastructure of the area, in addition to the construction of a new Olympic Park by the Black Sea coast.

The DIMMINUTOR® reduces wastewater solids in open channel wastewater installations and wet wells. It was selected by virtue of its unique design that features reliability and ease of maintenance. The owner was shown a similar installation nearby and was impressed with the unparalleled design features of the unit. While other comminutors being considered required disassembly of the entire unit to replace even one of the many cutters, the DIMMINUTOR features only a few replaceable parts. Each cutter can be independently replaced without unit disassembly. Additionally, there are no mechanisms or seals down at the gritty channel bottom while other designs have bottom bearings and seals subject to wear from grit.

Each DIMMINUTOR is equipped with a submersible motor. Unlike immersible motors, the submersible motor is designed to operate while submerged in water or sewage for unlimited time periods.

“Franklin Miller is very pleased that the DIMMINUTOR was part of the Sochi Olympics with one of the largest installations in the world,” says Dave Schuppe, VP of Sales, Franklin Miller.
