A Powerful Alternative to Traditional Water Treatment Technologies
Klarolaks™ is an advanced, safe-in-use chemical technology that delivers a multi-active, broad-spectrum biocide with exceptional stability and performance.
Designed for today’s water treatment challenges, it provides powerful microbial, fungal, viral, and algal control while reducing the environmental and operational costs associated with using traditional oxidants.
Why Klarolaks™?
A major development in water treatment technology.
Developed over two decades and refined through extensive global testing, Klarolaks™ represents a breakthrough in oxidising biocide chemistry. Its unique formulation enables in-situ generation of chlorine dioxide and active chlorine directly within water systems, creating an exceptionally durable and effective disinfectant.
Simplified dosing with no hazardous chemical mixing. Just a single, stable, ready-to-use product.
The Chemistry Behind Klarolaks™
A Unique Mixed-Oxidant System
When added to water (pH < 10), Klarolaks™ initiates a controlled equilibrium reaction:
-
Active chlorine (HOCl/OCl⁻) is created from sodium hypochlorite
-
Chlorine dioxide (ClO₂) is produced by oxidation of sodium chlorite by active chlorine
-
Together they form a complex oxidant system that features an extended biocide release mechanism
Why This Matters
Conventional chlorine dioxide generation has several disadvantages:
-
It requires sophisticated on-site generators to apply hazardous multi-component mixes, adding risk to health & safety, plant integrity and cost
-
It is quickly consumed by reactions with bacteria and biofilms, losing residual strength and prolonged protection against microbial regrowth
-
Generated chlorine dioxide in water is present as dissolved gas which degrades rapidly above 25°C and is lost to atmosphere in cooling towers, spray systems or in warm/hot water systems
Extended Biocide Release (EBR)
The equilibrium between chlorite, free chlorine, and chlorine dioxide means:
-
Chlorine dioxide is regenerated in situ after reacting with organics
-
Biocidal performance is prolonged even at a low dosage
-
Klarolaks™ exists chemically as part of the water phase and is not lost through gassing off in cooling towers or spray systems
This creates a potent, long-lasting oxidant, superior to available traditional technologies.
Key Technical Advantages
1. Exceptional Stability - Even at High Temperatures
Unlike sodium hypochlorite, which degrades rapidly (losing active strength and forming the toxin, chlorate), Klarolaks maintains a level of available chlorine with no measurable loss in biocidal efficacy at ambient temperatures (25–50°C).
This means:
-
Safe long-term storage
-
Consistent performance in hot climates
-
Minimal chlorate accumulation
-
Minimal product wastage
2. Superior Microbial & Biofilm Control
Independent studies show Klarolaks™ can achieve:
-
Greater than log 6 reduction in EU standard bacterial and viral tests to meet drinking water approval at less than 0.5ppm free chlorine
-
Effective bacterial kill beyond 24 hours on a single dose in stored water applications
-
Biofilm eradication at 0.5–1.5 ppm dosage
-
Efficacy across a broad pH range (4 to 9.5)
By contrast, hypochlorite loses efficacy rapidly, especially above
pH 7.5.
3. Reduced Product Corrosivity
Compared to other oxidising biocides, including chlorine, corrosion testing on 316 stainless steel shows Klarolaks™ causes far less metal attack, to support longer asset life and reduced maintenance costs.
Its formulation also prevents gassing in water systems to alleviate issues with headspace corrosion in vessels, holds, storage tanks and process/manufacturing equipment.
4. Lower Environmental & Operational Impact
Thanks to its stability and efficiency:
-
Lower chemical consumption
-
Fewer deliveries & reduced packaging waste
-
Minimal harmful by-product formation (e.g., AOX, chlorate)
-
No hazardous mixing or generator maintenance
Compared with hypochlorite, peracetic acid and bromine systems, Klarolaks™ demonstrates superior cost-in-use and easier handling.
