Detail_Flocculator_Rapid_Mixer_(anco).pdf

This is a technical specification document for the City of Bradenton, Florida, detailing the design and operational requirements for a flocculator component of the Sedimentation Basin and Flocculator No. 2 rehabilitation project at the Bradenton Water Treatment Plant. The flocculator is designed to process water flow rates of 15 million gallons per day (MGD) and consists of multiple compartments with mechanical mixing capabilities. The document specifies detailed construction requirements including basin dimensions, baffle configurations, mixing paddle specifications, and material standards. The flocculator unit is engineered to operate with variable speed motors to optimize flocculation efficiency across different flow conditions, with compartments designed to provide appropriate retention time and mixing intensity for suspended particle agglomeration before water enters the sedimentation basin.

The specification document establishes performance criteria and mechanical equipment standards for the flocculator rehabilitation, including paddle blade materials, drive shaft specifications, and gearbox requirements. The document references compliance with applicable water treatment industry standards and includes detailed technical drawings and performance parameters. Pricing for the flocculator equipment and installation would be incorporated as a line item within the broader bid for the complete Sedimentation Basin and Flocculator No. 2 rehabilitation project, with costs subject to contractor proposals and City evaluation during the competitive bidding process.
