diffusers on the current aeration system operating in the facility. The Jordan Basin Water Reclamation Facility has been in operation for nearly 12 years, and facility staff have determined that the minimum air flow required to prevent diffuser fouling on existing ceramic diffusers is detrimental to process and aeration control. JBWRF is seeking to replace 9” ceramic fine bubble diffusers with membrane fine bubble diffusers to allow better process air control and optimization of turbo blowers supplying the air to each basin. This project is intended to replace the diffusers only, while maintaining the existing air distribution piping and grid configuration. The District has drawings of each aeration tank and diffuser configuration, along with a total number of diffusers to be replaced. An agreement may be executed with the successful bidder(s) for two process trains to be completed in 2024. The District reserves the right to award diffuser replacement services to one bidder, or split the award between two or more bidders. The District intends to replace all diffusers in the designated trains, one tank after the other to provide adequate time to take trains offline, drain, clean, and prepare the tanks before work is completed. It is anticipated that each process train project will be completed in one trip, the time between process trains to be determined by facility staff. JBWRF currently utilizes 9” ceramic diffusers. The system was installed during construction of the facility in 2012. Sanitaire was the original supplier of the aeration system. Exhibit “A” contains the original design criteria, tank depths, volume, oxygenation, and number of aeration diffusers per tank. The membrane diffusers should provide equivalent aeration to the tanks within existing aeration grids. Contractor shall demonstrate that diffusers are compatible with existing system and supply the necessary amount of aeration and are a direct replacement of existing diffusers. Contractor shall provide estimated longevity or life expectancy of the membrane diffusers, as provided by diffuser manufacturer. Each train has six (6) Fine Bubble Ceramic Aeration grids, two grids for each of the three aeration tanks. Some diffusers have been capped and the ceramic discs removed to reduce the amount of aeration in each zone. The current 9” ceramic disc diffusers will be replaced with membrane diffusers and any necessary parts to “retrofit” the new style of diffuser to the existing system. The total number of diffusers to be replaced is 3,372 per train, or a total of 6,744 diffusers for the project. The District would like to purchase an additional 300 membrane diffusers, for a total of 7,044 diffusers. The District would also like to purchase adequate accessory parts including, but not limited to, gaskets, plates, couplers, or fittings to install the diffusers, to add to their inventory for future minor repairs or replacements. Parts not to exceed 50 installation “kits”.
