Prediction models for monitoring wastewater COD load

Toihan's prediction model estimates the organic load in wastewater based on production data. The model utilizes mill production data to produce a forecast of the COD load arriving at the treatment plant several hours ahead.

Benefits of the prediction model:

• Load forecast for the upcoming hours
  The model helps anticipate load peaks and identify changes in load levels before their effects are visible in measurements.

• More efficient process control
  With the forecast, process adjustments can be ensured to be cost-effective and aligned with the goals set for wastewater treatment.

• Improved response time in changing situations
  The forecast provides additional time to respond with control measures to load changes caused by production shifts. More accurate control reduces the occurrence of disturbances in wastewater treatment plant and the annual load on environment.

• Easy integration into control systems
  The prediction model can be integrated into the mill's control system to support operational decision-making.

Toihan Oy also offers services for maintaining the prediction model and for regular version upgrades.
