SUMMARY
The City initiated a Request for Proposals (RFP) on March 4, 2025 to select a supplier for polymer beginning in Fiscal Year 2025-2026. The selection process included a written proposal, lab testing, and a real-world trial. Polydyne Inc. was selected as the preferred vendor.
RECOMMENDATIONS
Staff recommend City Council adopt a Resolution to approve and authorize the City Manager to execute a Non-Professional Services Agreement with Polydyne Inc. for the selection and supply of polymer for dewatering processes at the Water Pollution Control Plant (WPCP) for a total not to exceed amount of $786,000 for a period of three years at the price quoted in Polydyne's response to the RFP, with an option to extend terms by two years if mutually agreed upon by the City and Polydyne, Inc.
BACKGROUND
Polymer is a chemical used in the wastewater industry to "thicken" solids streams after the solids are removed from the wastewater. At the WPCP, polymer is used in two processes: to thicken solids removed from the secondary process and to thicken solids removed from the digester to prepare them for drying. Because there are subtle differences in the constituents of the solids, no single polymer works the best in every process at every treatment plant. Therefore, it is necessary to find the best polymer through testing of polymers both in the lab and in real-world tests. In addition, wastewater constituents can change over time and polymer companies are constantly developing new and better products. Polymer mixing and application may also make a difference for how much polymer is needed. For these reasons, service is a critical component of polymer procurement.
