Giorgio Foods WWTP Phase 1 – Lagoon Aeration System Improvements

Johnston Construction Company

• Upgraded the existing industrial wastewater treatment lagoon aeration system through installation of a new Parkson Biolac® W aeration system while maintaining wastewater treatment operations during construction.
• Installed new BioFlex/BioFuser aeration equipment, air-distribution piping, valves, supports, cabling, and associated appurtenances for the existing aeration basin.
• Sequenced installation of the new diffuser system in stages so portions of the replacement aeration system could be installed and tested while the existing treatment process remained operational.
• Furnished and installed new above-ground process air piping, concrete foundations, structural supports, handrail improvements, and associated miscellaneous metals.
• Removed existing underwater aeration equipment and existing perimeter safety railing as part of the lagoon renovation.
