Vendor quote
Polymer is a product used at the plant to coagulate sludge.
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. Our current product
continues to perform well, producing a dry product that saves the City money in trucking
and disposal costs. The Polydyne products we are currently using are Clarifloc NE2180
for the screw presses and Clarifloc C-6266 for the belt filter presses.
Polydyne is offering the City a unit price of $1.21/lb for both of these products for the
FY21 year, with a potential savings for a full 5000 gallon load at $1.15/lb. Our annual
estimated cost for these two polymers is $450,000.
