Title

Consider and take action on a resolution authorizing a three-year agreement with Polydyne, Inc. for Polyacrylamide Cationic Emulsion Liquid Polymer at a unit price of $1.64 per pound in an amount not to exceed $282,900 (Director of Public Works)

Background:

Approval of this resolution will authorize an agreement with Polydyne, Inc. for the purchase of Polyacrylamide Cationic Emulsion Liquid Polymer for a period of three (3) years from October 1, 2023 through September 30, 2026, in an amount not to exceed $282,900 with the option to renew for two (2) additional one-year periods.

This commodity is used for municipal wastewater sludge conditioning in the dewatering process at the City’s Dallas Salmon Wastewater Treatment Plant (DSWWTP) and Southwest Water Reclamation Facility (SWWRF). Polymer acts as a flocculent agent in the solids/water separation of digested sludge, significantly increasing the water removal efficiency, reducing the overall volume of sludge disposal, therefore reducing costs.

The City’s current cost of polymer is $1.25 per pound versus the proposed $1.64 per pound and representative of the current volatile market.
