SICTOX
Intelligent Toxicity Control System
SENSARA's SICTOX algorithm detects episodes of toxicity and prevents their entry into the plant, thus protecting the biomass.
Toxicity Test
The SICTOX algorithm relies on toxicity testing to detect episodes early.
El equipo realiza el test en 2 etapas:
- pumping mixed liquor to the respirometric chamber, aeration until saturation ("endogenesis"), addition of ammonium chloride and calculation of the nitrification rate Rsmax[Sludge+Substrate],
- pumping of mixed liquor to the respirometric chamber, pumping of influent sample, aeration until saturation ("endogenesis"), addition of ammonium chloride and calculation of the nitrification rate Rsmax[Sludge+Substrate+Sample],
Inh (%) = 100 * (1 – Rsmax[Fango+Sustrato+Mtra]/Rs.max[Fango+Sustrato])
Nitrification Test
The SICTOX algorithm relies on the nitrification test as confirmation of the toxicity input.
Control Loop
Based on the results of the nitrification and toxicity tests, a mixed control loop is established that guarantees the detection of toxicity and can act early (bypass) before it enters the biological.
