VFA CONTROL

Acidification control of water circuits

Reduce the use of fresh water without damaging process water acidification.
Define key operating indicators to limit the negative effect of volatile fatty acids (VFAs) on the process and paper/cardboard quality.
Demonstrate the benefits of different strategies (aeration, mixing, etc.) to limit anaerobic bacterial activity in water circuits.
Improve production yields and paper/cardboard quality
Improve site safety by reducing gas emissions (H2, H2S) below toxicity and explosivity thresholds.
