Is your wastewater facility at maximum treatment capacity? Unable to meet stricter effluent requirements? Looking for a treatment solution that will upgrade your current facility? We have 3 simple ways to increase treatment efficiency without making changes to your basin: Retrofits, Supplemental Aeration and Upgrades.


Aeration Industries’ upgrade, supplemental, and retrofit solutions and services help wastewater treatment plants meet stricter regulations and maximize capacity while saving energy. 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. Whether your facility needs to upgrade, supplement, retrofit, or expand capacity, Aeration Industries offers 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 solution that is right for you.

Upgrade & Retrofit Applications:

  • Aerobic digesters
  • Anoxic basins
  • Anaerobic basins
  • Aeration tanks
  • Chemical mix tanks
  • Lagoons
  • Oxidation ditches
  • Supplemental aeration/mixing

What is a system RETROFIT?

  • Replacing your overworked or outdated system with new units (or) with more advanced aeration technology
  • Replacing aeration and/or mixing equipment that has reached the end of its operation lifecycle
  • Replacing systems that are no longer considered effective


  • Additional aeration
  • We can create a customized solution that leverages your existing equipment while adding supplemental air to your existing infrastructure

What is a system UPGRADE?

Providing more oxygen and/or mixing, with or without implementing an automated control system, to meet increased biological treatment needs resulting in an ability to meet a growing population or stricter effluent limits. Effluent limits are often impacted by BNR (biological nutrient removal) requirements. A biological treatment upgrade doesn’t usually require new construction, it can be accomplished within your existing aeration basins. Or, a combination of any of the following:

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

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 modify 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 wholly 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.
