AERprocess AERprocess

Aerzen’s AERprocess Dissolved Oxygen Control is an integrated solution for controlling the dissolved oxygen (DO) concentration in the activated sludge treatment process and the blowers used to generate the process air flow requirement. The AERprocess system is able to maintain DO concentrations at their set points using a smart and efficient control strategy.

AERemote AERemote

The Aerzen AERemote Monitoring System (RMS) is a comprehensive monitor that can be attached to any blower or compressor to capture real-time activities and conditions.

AERsmart AERsmart

Aerzen has the best machine technologies for the job, with blower, hybrid and turbo. AERsmart, the new intelligent machine control, raises their performance even further. AERsmart distributes air flows optimally between the various technologies and their individual efficiency levels. End result: standalone efficiency levels close to the theoretical maximum. Additional savings of up to 15 percent.

    Big Air: Aerzen Introduces Turbo Blower For Large Treatment Plants

    Aerzen USA has long preached — and excelled in delivering — "right-sized" blower solutions, offering energy efficiency by producing the proper amount of air for the application. Until recently, however, the company did not have an option for the largest of wastewater treatment plants. That has changed with the introduction of the Multicore series turbo blower, which is described in the following video by Tom McCurdy, National Sales Manager for Aerzen's Environmental Group.

  • The Hidden Costs Of Aeration
    The Hidden Costs Of Aeration

    To ensure that aeration equipment will provide not only the best overall solution for their treatment needs but also the lowest total cost of ownership, design engineers and plant operators must take into consideration three primary factors: blower selection, right-sizing, and smart control systems.


  • Stepping Up To Smart Aeration
    Stepping Up To Smart Aeration

    According to the U.S. EPA, municipal water and wastewater treatment systems account for 30 to 40 percent of the total energy used by municipalities in the United States. In wastewater treatment, the biggest chunk of this energy consumption comes from aeration. Within a typical WWTP, the aeration equipment used to maintain the required dissolved oxygen (DO) levels in the activated sludge process can account for as much as 60 percent of the total plant energy use (Source: EPA.gov). As municipalities and plant operators look for ways to minimize energy use and contain operating costs, aeration is a natural area of focus.
