BACKGROUND This is the smallest of three centrifuges located at our Main Wastewater Treatment Plant, and is used for drying WWTP solids in preparation for disposal at our landfill. These units operate by rotating solids in a cylindrical bowl at high speed to create 2000x-3000x the normal force of gravity. Originally purchased in the mid-1990's at approximately $132,000, this type unit requires a lot of expensive maintenance and repair throughout its service life due to the extreme duty conditions in which it operates. This unit recently began excessive vibration, a sign that it is out of balance and in need of dismantling, repair, and re-building. During this type of maintenance, bearings and up to 250 tiles in the unit will also be replaced and tested to meet factory tolerances. It also comes with a 1-year warranty on parts and workmanship. The unit was removed by B & P Process Equipment and Systems for assessment and determination of scope of service/repairs. We used B & P's provided scope of repairs for other repair shops to submit quotes.
