City of Nashua, Public Works Division
Board of Public Works Meeting Date: May 25, 2022
David Boucher, Superintendent
Wastewater Department
Polymer
To approve Change Order #1 for the purchase of chemical Polymer from Polydyne of
Riceboro, GA in the amount of $39,000.00. Funding will be through: Department: 169
Wastewater; Fund: Wastewater; Account Classification: 61 Supplies & Materials.
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.
The original fiscal year funding of $450,000 for the annual purchase of Polymer was
approved at the June 24, 2021 BPW Meeting and was based on historical usage. Due to
supply chain issues, the wastewater facility had to purchase smaller emergency loads at a
higher cost throughout the beginning of 2022 to ensure we would not run out of
chemicals and were able to maintain our treatment process. We are requesting additional
funding to complete the fiscal year.
