WwTF Coagulant

The City of Barrie has issued Request for Information FIN2026-2331 to identify alternative coagulants for total phosphorus removal at its Wastewater Treatment Facility. The facility currently utilizes approximately 2,000 dry tonnes of aluminum sulfate annually and is seeking solutions that can maintain or improve treatment effectiveness while reducing chemical costs, enhancing operational efficiency, and supporting long-term sustainability. Proposed solutions must be compatible with existing infrastructure, including Watson Marlow peristaltic pumps, schedule 80 PVC pipe, and PVC #328 lined concrete storage tanks, and must not adversely affect effluent quality or compliance with the facility's Environmental Compliance Approval. This RFI is for information-gathering purposes only and does not constitute a formal competitive bidding process or a legally binding contract. The City will evaluate alternative coagulants based on economic factors, such as annual chemical costs, and treatment effectiveness regarding the removal of soluble reactive phosphorus, total phosphorus, and total suspended solids, as well as impacts on biosolids production and downstream processes. Responses must be submitted electronically via the City's Bidding System by November 03, 2026, at 2:00 PM local time. Submissions should include the completed Respondent Submission Form and supporting technical documentation, such as Safety Data Sheets, while avoiding the inclusion of proprietary or confidential information.
