Precision Biocontrol - Smart Microbe Management for Water Intensive Processes
• At-line biocide production from process water
• Electrochemical generation of biocides• Commercial electrolysis unit,
installed in-line, with a smart controlunit
• New solutions to control microbial contamination
• Capex-opex at paper mill less than 0.2 €/ton

Efficient biocide concept for papermaking
Acceptable Bacterial Count with 1% Dosage
• Effective also at high solids contents such as in broke systems
• Salt/brine addition improves efficiency
• COD load reduces efficiency
• Tailormade solutions for each process
