Bids Are Invited For Wastewater Treatment Plant Dewatering Polymer Procurement in Canada

Work Detail

Wastewater Treatment Plant Dewatering Polymer Procurement . The Resort Municipality Of Whistler (Rmow) Is Inviting Experienced, Reliable, And Qualified Suppliers To Provide A Proposal For The Supply And Delivery Of Dewatering Flocculating Agent Polymer To The Rmow Wastewater Treatment Plant (Wwtp). The Rmow’S Wwtp Treats Wastewater From Whistler Using An Enhanced Biological Phosphorus Removal (Ebpr) Process. Within The Solids Handling Building, The Plant Has One Dissolved Air Flotation (Daf) Tank For Waste-Activated Sludge (Was) Thickening And Two Centrifuge Dewatering Units. The Was From The Two Bioreactors Is Pumped To The Daf For Thickening. Polymer Is Added To The Was Before The Daf Tank To Enable Higher Thickening And Improve Solids Capture Performance. The Thickened Wasteactivated Sludge (Twas) From The Daf Tank Is Pumped To One Of Two Twas Storage Tanks. Additionally, Primary Sludge Is Removed From The Primary Sedimentation Tanks And Then Pumped To A Primary Sludge Storage Tank Located Adjacent To The Twas Tanks. The Twas And Primary Sludge Are Blended At An Operator-Designated Ratio. Prior To Sludge Entering The Centrifuges, Polymer Is Added To Bulk The Solids And Improve The Separation Of Solids And Liquid. The Plant Stores Liquid Polymer Agent In 1,040 Kg Intermediate Bulk Containers (Ibc). The Polymer Is Injected Using The Prominent Promix S & M Polymer Blending Systems. Polymer Is Gravity-Fed To The Polymer Dosing System, Discharged To The Daf Tank, And Centrifuged At Operator-Adjusted Rates. Jar Testing Will Take Place At The Wwtp Between January 26Th And 30Th . Suppliers Must Pick A Day To Perform Testing During The Outlined Dates. Days Will Be Given Out On A First-Come, First-Served Basis. Test Results Must Be Included In The Quote Submission (See Appendix A For A Sample Report). Suppliers Will Be Jar-Testing Primary Sludge And Twas At The Following Ratios: 30/70, 40/60, 45/55, 50/50, 55/45, 60/40, And 70/30.
