Case study: BIOINGER 5380 application in causticization sludge and TRS reduction

Faced with increasingly stringent environmental regulations, pulp mills are seeking to minimize TRS (total reduced sulfur) emissions. Lime kilns are particularly susceptible to variations in these compounds.

The solution

INGER developed the BIOINGER 5380 application to reduce sulfides present in causticizing sludge, keeping the TRS below regulatory limits even during operational fluctuations.

Results

• Average decrease in TRS greater than 25%
• Effect detected in less than 1 minute
• Versatility of dosage according to requirement
• Continued use during emergencies without affecting productivity
