The existing facility is an aerated lagoon facility, followed by continuous backwash filters and UV disinfection. The adjusted proposed improvements included a headworks modifications, construction of a three-train Kruger Triple-ditch activated sludge system, and replacement of the UV system. Two aerobic digesters and facultative digested sludge storage were proposed for solids handling.

| South Bay International Wastewater Treatment Plant San Diego, CA |
VE study of the upgrade of this existing advanced primary treatment plant, treating flows from Tijuana, Mexico . The proposed facilities consisted of a three-stage lagoon system, with anaerobic, complete-mixed and partially mixed lagoons, and a recycle system to transfer waste solids from the completely mixed lagoons to the anaerobic lagoons for digestion. The initial anaerobic lagoon will provide initial treatment of the strong (approximately 440 BOD) influent flows, and will also digest the primary and secondary solids generated at the facility. The new lagoon system was being designed for an average flow of 25 mgd and a peak flow of 75 mgd. The proposed improvements also included extensive landscaping and also special fencing, because of the proximity of the plant to the U.S.-Mexico border. |
