Proposal
The City of St. Cloud, Minnesota is soliciting proposals from qualified vendors for the
removal of the existing Polychem chain and flight equipment and installation of newly
procured Polychem chain and flight equipment within an existing scum well.
Background Information
The original Polychem scum skimmer drive system, manufactured by Brentwood
industries, was installed in 1974 at the St. Cloud Nutrient, Energy, and Water (NEW)
Recovery Facility. This skimmer drive gear system is operated to divert fats, oils and
greases and scum from the facility’s primary clarifier tanks. The current daily average flow
to the facility is 10 million gallons per day, MGD, and the scum and grease are
concentrated and collected by rotating weirs, which then flows by gravity to the scum
well. The drive mechanism in the scum well conveys the scum and grease to a sump
where it is pumped by pneumatic scum ejectors to the anerobic digesters for further
processing.
Location: 525 60 Street South, St. Cloud, MN 56301
Existing system details:
15 FT Long x 8 FT Wide x 3 FT AWD, 3 Shaft System

expenses to remove existing and install newly procured equipment and components.
Completion of removal and installation shall not exceed ten (10) working days after a
pre-approved start date with the customer.
