The risk of permit violations and downtime are high.
Don’t let your DO levels get low.

Are you unable to meet stricter effluent requirements?
Is your wastewater facility at maximum treatment capacity?
Looking for a treatment solution that will upgrade your facility?


As infrastructure ages, operations and energy costs increase, and regulations become increasingly stringent; wastewater treatment plants must look for cost-effective ways to upgrade their plants. Aeration Industries’ retrofit/upgrade and supplemental aeration solutions and services help wastewater treatment plants meet stricter regulations and maximize capacity while saving energy.  If you are looking to expand capacity, we can offer a variety of solutions that work to reduce costs, improve efficiency, comply with new effluent regulations, and save energy. Let’s partner to create a customized aeration system retrofit solution that is right for you.

Simple Ways to Increase Treatment Efficiency without Expanding your Plant

Wastewater Aeration Retrofits

Need more oxygen and mixing?  A biological treatment upgrade doesn’t usually require new construction; it can be accomplished within your existing aeration basin. We offer the following solutions:

  • Replace outdated equipment or systems with our advanced aeration technology
  • Replace aeration and/or mixing equipment that has reached the end of its operation lifecycle
  • Replace systems that are no longer considered effective

Our equipment offers:

  • More oxygen
  • More mixing
  • Implementing an automated controls package to accomplish BNR
  • Implementing an automated controls package to reduce energy consumption
  • Reducing energy consumption to accomplish equal or better effluent quality, with or without the use of a controls package

Increase Wastewater Treatment Capacity with
Supplemental Aeration Systems

Is your current system not meeting regulations? Looking to expand treatment capacity while still utilizing your current equipment? We can supplement air with our flexible, modular equipment within your existing infrastructure. We offer:

  • Customized solutions while leveraging your existing equipment
  • Ability to meet regulations on a tight timeline
  • Simple installation and maintenance
  • Assurance that your plant will not lose production time
  • Quick response rental program for emergency situations

Benefits of combining Aire-O2 Triton Aerators and
Diffused Aeration Systems

Achieve performance requirements by combining surface aeration with diffused aeration systems. Our Aire-O2 Triton can bring a struggling diffused aeration basin back up to optimal performance by quickly adding oxygen capacity and mixing.

  • Instant capacity (SOTR) increase without the need to interrupt production or drain the basin
  • Increase aeration efficiency (SAE) with consistent aeration
  • Keep solids in suspension with mixing-only option; when oxygen demand is low, Aire-O2 Triton blowers can be turned off to save electricity. When demand is high, Tritons can be activated instantly
  • Modular equipment allows for flexibility without making changes to infrastructure
  • Aire-O2 Triton offers consistent, reliable performance throughout the life of the aerator

Lagoon Conversions

As federal and state regulatory agencies continue enforcing more stringent nutrient removal policies and increasing the plant capacity of wastewater systems becomes essential, the cost of maintaining a productive wastewater system skyrockets. While pricey, meeting the new goals set for the municipalities and industries is an unavoidable necessity. But, there is an alternative to starting from scratch. “Lagoon Conversions,” better known as lagoon upgrades, are a cost-effective means to modifying existing wastewater systems in order to accomplish the growing demands on the wastewater systems.

Tackling new regulations dealing with lower biological oxygen demand (BOD), total suspended solids (TSS), and ammonia levels is incredibly expensive. Managing those regulations as well as biological nutrient removal (BNR) while controlling the cost of new designs, plant modifications, and new plant construction is incredibly challenging. Historically, when faced with these stringent effluent limits and/or increases in plant influent flows or loadings, engineers have redesigned an entirely new plant to ensure compliance with the effluent requirements.

Fortunately, re-engineering a new plant is not the only solution. Instead, upgrading existing lagoon systems by preserving and using as much of the existing system and equipment as possible is a feasible alternative. Lagoons are intentionally designed to be easy to operate and maintain and to produce effluent capable of achieving conventional secondary treatment.
