Intelligent aeration control system

Intelligent aeration control systemSICAIR

Real time process control and optimization

SICAIR is an excellent system designed to optimize oxygen consumption in wastewater treatment plants, particularly during nitrification and denitrification processes.

Unlike traditional systems that rely on inaccurate estimates of nitrification rates or use ammonium probes with computational delays, SICAIR uses continuous respiration to monitor bacterial respiration dynamics (OUR/AUR nitrification rates) in real-time and accurately automatically adjust aeration.

SICAIR works together with SN8 breathers and sewage plant SCADA to ensure that oxygen supply is precisely aligned with biomass demand at all times, thereby reducing energy consumption and maintaining the stability of biological processes. In addition, SICAIR can automatically adjust in case of accidents such as rainfall or overload, and apply real-time corrections without interrupting control.

SICAIR Differences

The fundamental difference between this system and traditional aeration control systems is that the SICAIR system directly pre evaluates a fundamental variable, such as the kinetics of bacterial respiration at each moment (OUR/AUR nitrification rate).

Assessment and control of rainwater

For the dilution process of rainwater, the system detects it through comprehensive respiration detection and HRT hydraulic retention time data, and applies correction factors to recalculate the aeration rate.

overload

Similarly, when the system detects overload, it recalculates the aeration rate through comprehensive breath testing and sewage plant probe detection, and applies correction factors.

data link

The respiratory measurement system SN8+SCAIR communicates bidirectionally with the SCADA of the sewage treatment plant. The respiratory measurement system sends all signals through MODBUS, and then SCADA shares the signals with the respiratory measurement system.

In this way, the factory aeration system defaults to working through a breathing apparatus, but in the event of a malfunction, it will automatically switch to traditional probe control to prevent the factory from losing control at any time.

Problematic activated sludge process

Slow dynamics make it difficult to make decisions when problems arise. No matter what measures are taken, their impact on the process cannot be clearly observed within a few days.

On the one hand, it is important to detect problems as early as possible, and on the other hand, to make the right decisions from the beginning. However, it is impossible to evaluate biological processes through physical or chemical measurements, requiring direct information on biomass and the impact of the wastewater to be treated on it, which the SN8 breather can achieve.
