Description
The City of Boise is seeking bids for the purchase of two sludge mixers to replace existing mixers at the West Boise Water Renewal Facility. The sludge mixers will be used to mix wastewater sludge in two of the city's anerobic digesters. The scope of work includes submittal preparation, fabrication, and shipment services. The city is looking for a supplier who can provide high-quality sludge mixers that meet the specified requirements and can be installed and maintained with ease. Key aspects of the project include:
• The sludge mixers must be capable of recirculating sludge at a nominal capacity of not less than 10,000 gpm, with flow directed in either the upward or downward direction.
• The mixers must be suitable for installation in the existing 27-inch ID digester draft (seal) tubes.
• The supplier must provide operation and maintenance manuals, as well as training and support for the installation and maintenance of the sludge mixers.
• The city is looking for a supplier who can provide a warranty for the sludge mixers and provide timely and effective maintenance and repair services.
Some of the key requirements for the sludge mixers include:
• The mixers must be designed to withstand the corrosive environment of the digesters and must be made of materials that are resistant to corrosion.
• The mixers must be easy to install and maintain, with a design that allows for easy removal and reinstallation.
• The mixers must be capable of pumping in both the upward and downward directions, with a "ragless" design that can handle stringy or fibrous materials.
The city is seeking a supplier who can provide high-quality sludge mixers that meet these requirements and can provide excellent customer service and support.
