Retrofitting Aging Infrastructure: Seamlessly Integrating Jet Aeration Into Existing Tank Designs

Aging industrial wastewater systems often struggle with unreliable fine bubble diffusers that require cleaning or replacement every few years—forcing operators into lengthy basin shutdowns, state-level coordination, and costly downtime. Jet aeration provides a practical retrofit alternative that can often be installed while tanks remain in service, avoiding the risks and logistical challenges of taking a basin offline. Its long service life—typically 20 to 30 years—and airlift backflush capability allow operators to clean nozzles without draining the tank, reducing maintenance to routine pump and blower oil changes. Retrofit options include permanent dry-pit installations with drop-in or skid-mounted equipment, or lower-cost submersible pump configurations for smaller tanks. Jet aeration also offers substantial energy savings—around 30% less than diffusers in industrial wastewater—thanks to higher mass transfer efficiency. When dry basin work is required, careful documentation of tank geometry, construction materials, blower data, and wastewater characteristics ensures a seamless design process. With rapid installation timelines and straightforward performance validation, jet aeration provides a low-disruption, high-reliability solution for extending infrastructure life and improving treatment performance.
