In addition, in <br />order to ensure functional polymer is available, staff recommends that the City Council authorize <br />purchasing up to $100,000 of polymer from SNF Polydyne, Inc. in Fiscal Year 2019-20. <br />BACKGROUND <br />Polymer is a chemical used in the wastewater industry to “thicken” solids streams after the solids <br />are removed from the wastewater. At the WPCP, polymer is used in two processes: to thicken <br />solids removed from the secondary process and to thicken solids removed from the digester to <br />prepare them for drying. <br />Because of subtle differences in the constituents of the water, no single polymer works the best in <br />every process at every treatment plant. Therefore, it is necessary to find the best polymer through <br />testing of polymers both in the lab and in real-world tests. In addition, most wastewater <br />constituents change over time and polymer companies are constantly developing new and better <br />products. How the polymer is mixed and applied may also make a difference for how much <br />polymer is needed. For these reasons, service is a critical component of polymer procurement. <br />The WPCP has been using the same polymer since 2013, after receiving a bid through the Bay <br />Area Chemical Consortium (BACC). The BACC no longer includes polymer in their bid process, <br />so WPCP staff opened a Request for Proposals for polymer selection and supply. <br />Page 1 City of San Leandro Printed on 10/30/2019 <br />120
