About this file
This document is a bid specification form for OCWUT 07-26 Exhibit A, seeking Virgin Bituminous Granulated Activated Carbon (GAC) for water treatment purposes. The form requires bidders to complete a detailed specification and evaluation sheet covering critical technical requirements for the activated carbon, including certification standards, chemical properties, and performance characteristics. Bidders must provide comprehensive responses to 15 specific criteria, such as ANSI/NSF Standard 61 certification, AWWA-B604-18 compliance, particle size distribution, and various chemical performance metrics.
The specification form outlines precise technical requirements for the GAC, including specific ranges for particle size (8 x 20 Mesh), apparent density (0.35-0.42 g-cc), effective size (1.0-1.20mm), and maximum percentages for ash content (4%) and moisture (8%). Key performance indicators like iodine number (minimum 500 mg/g), tannin number (maximum 280), and molasses number (minimum 300) are also specified. The form emphasizes that failure to complete the specification/evaluation requirements may result in bid rejection, and bidders must submit this form along with their chemical specification sheets to be considered for the contract.
