SUMMARY AND RECOMMENDATIONS
Staff recommends City Council adopt a Resolution to approve and authorize the City Manager to execute a Non-Professional Services Agreement with Solenis, LLC for the selection and supply of polymer for dewatering processes at the Water Pollution Control Plant (WPCP). In addition, in order to ensure functional polymer is available, staff recommends that the City Council authorize purchasing up to $100,000 of polymer from SNF Polydyne, Inc. in Fiscal Year 2019-20.
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 of subtle differences in the constituents of the water, 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, most wastewater constituents change over time and polymer companies are constantly developing new and better products. How the polymer is mixed and applied may also make a difference for how much polymer is needed. For these reasons, service is a critical component of polymer procurement.
The WPCP has been using the same polymer since 2013, after receiving a bid through the Bay Area Chemical Consortium (BACC). The BACC no longer includes polymer in their bid process, so WPCP staff opened a Request for Proposals for p...
