Vendor quote
Polymer is used at the Wastewater Treatment Facility to coagulate the sludge used
in the presses. Periodically, the Facility has different companies come in and do
bench testing to ensure we are using the best polymer for the best price to meet
our needs. Recently we selected a new product for our gravity belt thickeners, at a
lower price point, which results in savings for the City. This product is Polydyne
C-6266.
In FY17, we set up Polydyne’s PO to provide us polymer for our Huber brand
screw presses. At this time, wed like to increase the amount of the PO to now
include the additional cost of the product for our gravity belt thickeners. With the
approval of this, we will release the same amount encumbered for the gravity belt
thickeners from the old vendor to make the funds available in the chemical
budget.
