Cooling & Process Water

Microbiological activity in cooling and process water can lead to several serious problems if not controlled. Some microbes are pathogenic which creates a risk to health, and certain bacteria are responsible for over 50% of industrial water system corrosion. Bacteria produce gelatinous secretions called biofilm, to protect themselves from predatory microbes and adverse environmental conditions, that left unchecked can significantly impact energy costs by reducing heat transfer, restrict water flow and ultimately block critical waterways.

The Hidden Cost in Industrial Water Systems

Biofilm is not surface contamination, it is a structured microbial community embedded within a protective matrix that resists standard disinfectants. In gas scrubber towers, paper production circulation systems, cooling towers, and process water lines, biofilm accumulation reduces system efficiency, increases the frequency and cost of cleans, and creates conditions in which Legionella and other pathogens can thrive.

Many conventional biocides achieve only surface-level disruption; without biofilm penetration, regrowth occurs rapidly. Klarolaks™ generates active chlorine and chlorine dioxide in water, providing broad-spectrum activity that breaks down the biofilm matrix rather than simply treating the water column.

Vegetable Processing Facility

Overview:

Private borehole water supply consistently failing compliance for coliforms indicating pathogenic contamination. Sodium Hypochlorite at 2 ppm could not maintain adequate residual throughout the system. Failed tests resulted in product being discarded and lost revenue.

Result:

No coliforms detected since switching to Klarolaks™. Improved stability and lower chemical consumption noted by site.

Pulp & Paper

Overview:

Leading Paper Manufacturer

High microbial activity and slime growth across short and long circulation systems was causing paper defects, high biocide consumption, elevated costs, and strong workplace odours. Existing DNPA treatment failing to deliver consistent control.

Result:

74% reduction in biocide dosing resulting in a 35% annual cost saving. Paper defects eliminated and odours resolved. Stable microbiological control achieved across both circulation systems.
