Online activated sludge breathing apparatus

Online activated sludge breathing apparatusSN8

Real time process control and optimization

SN8 is an online breathing apparatus designed to interact with processes and serve as a tool for better control and optimization. For this purpose, SN8 consists of DO, temperature, pH, and ORP probes. It can control the main processes of sewage treatment plants: organic matter degradation, nitrification, and denitrification.

Detection and Parameters

Using the SN8 breathing apparatus, perform the following tests, which can continuously and automatically provide the following parameters:

● Comprehensive respiratory measurement: OUR (mg O2/l · h), SOUR (mg O2/g · h)

Nitrification rate: AUR (mg NH4/l · h), SAUR (mg NH4/g · h)

Denitrification rate: NUR

Hydraulic retention time (HRT)

● Oxygen demand

● Mud Age (TRC)

● Biodegradable COD

application

Toxicity. Leak detection.

Excellent aeration control (SICAIR) based on respiration measurement

Optimization of Denitrification

● Nitrification optimization

Optimization of Dilution Process in Aeration Tank

● Calculation of Biodegradable COD

Toxicity and leakage testing (such as choosing SICTOX)

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.
