Primary Clarifier Polychem Chain and Flight Equipment
Installation Services
Proposal
The City of St. Cloud, Minnesota is soliciting proposals from qualified vendors for removal of
existing Polychem chain and flight equipment and installation of newly procured Polychem
chain and flight equipment for an existing Primary Clarifier #4.
Background Information
The existing Primary Clarifier #4 Polychem chain and flight components were installed in 2010
and are showing significant signs of wear from 16 years in service. The configuration for Primary
Clarifier #4 consists of two longitudinal and one cross collector chain and flight drive system. This
configuration concentrates the settled solids towards the clarifier’s primary sludge pump sump.
From the sump these solids can more efficiently be pumped to the gravity belt table, GBT, for
further dewatering and solids processing. Floating solids are concentrated at the end of
longitudinal collector and collected by a tipping weir that is connected to the facility’s scum
well.
