Specifications include, but are not limited to: Providing Polymers at the Potable Water Treatment and Wastewater Treatment Facilities. The City invites interested firms to conduct jar tests and performance tests to determine their effectiveness for the following items: Polymers for settling floc in lime softening units. Polymers for flocculation of bio-solids in Dissolved Air Flotation (DAF). Polymers for flocculation of bio-solids in gravity belt thickener units. Location Approximate Quantity Processed Daily Description Springtree & Southwest* Water Treatment Facilities 10 & 1 MGD of water respectively Water with Lime Softening Treatment. Dry high molecular weight, anionic polymer is typically delivered in 55 pound bags is prepared by mixing with water in one 500-gallon polymer solution tank. Springtree Wastewater Treatment Facility 1,200 DT/Y of biosolids Bio-solids with Gravity Belt Thickening process. Liquid, cationic polymer typically delivered in 275- gal IBC totes and a polymer feed system pumps the neat polymer from the tote into a mixing chamber where it mixes with water. Sawgrass Wastewater Treatment Facility 1,900 DT/Y of biosolids Bio-solids with Dissolved Air Flotation Thickening process. Dry cationic polymer is typically delivered in 55 pound bags is prepared by mixing with water in one or more of the three 550-gallon polymer solution tanks. *Testing will not be required at the Southwest Water Treatment Facility. The successful polymer at Springtree Water Treatment Plant will be used at the Southwest Water Treatment Facility after bid is awarded. Firms that have submitted polymers for testing and have been approved need not respond unless they have new polymers to test. Each firm will be able to jar test any polymers they wish to test. However, only two (2) products per group can be submitted by each vendor for bidding purposes. Only firms that have successfully completed the testing program will be allowed to bid on the upcoming bids for each treatment process.
