ClO₂Sure: Single Chemical Chlorine Dioxide

ClO2Sure – Advanced Single-Chemical Chlorine Dioxide Water Treatment for Legionella Control & Biofilm Removal

ClO2Sure is a ground-breaking single-chemical chlorine dioxide product designed to enhance water quality, combat legionella, and remove biofilm in pipework. Unlike conventional multi-part or sodium hypochlorite treatments, ClO2Sure is safe, efficient, and easy to apply, providing a peace of mind that your water system is protected at every level—from cooling towers and potable water lines in hospitals to residential or commercial offices.

From poultry farms and paper mills to building complexes, ClO2Sure has consistently outperformed standard chlorine treatments. Its innovative equilibrium chemistry ensures minimal by-product formation, helping to protect public health, the environment and infrastructure. If you’re looking to enhance legionella or generalised microbial control and meet your water compliance obligations, ClO2Sure offers a safer, cost-effective, and regulatory-friendly approach.

Water Purification Treatment with ClO2Sure - Single Drum Chlorine Dioxide

Single-Chemical Chlorine Dioxide: No multi-component mixing required. This significantly reduces handling risks and simplifies dosing—leading to safer, more efficient use.
Peace of Mind Through Compliance: Backed by PT5 approval under the Biocidal Products Regulation for potable water, ClO2Sure meets regulatory standards for offices, hospitals, and residential premises.
Robust Biofilm Removal: Penetrates and disrupts bacterial colonies, tackling stubborn biofilms in pipework—a vital step for legionella control.
Low By-Product Formation: Thanks to equilibrium-based generation, ClO2Sure minimises chlorite and chlorate, ensuring your water remains safe.

Equilibrium Chemistry Explained

At the heart of ClO2Sure is its equilibrium-based generation of chlorine dioxide. When diluted in water, ClO2Sure releases active chlorine dioxide steadily, then re-generates it from by-products like chlorite. This self-sustaining approach:

Enhances overall efficacy
Extends biocidal contact time
Reduces total chemical consumption, giving you both cost savings and operational peace of mind

Fast & Broad-Spectrum Disinfection

ClO2Sure’s chlorine dioxide oxidises pathogens quickly, targeting:

Legionella, E. coli, and other waterborne bacteria
Viruses and fungi
Biofilm-forming organisms clinging to pipe surfaces

- Provides dependable legionella control in hot and cold distribution networks.
Poultry Farm Drinking Lines
- Demonstrated near-complete biofilm removal in pipework.
- Boosted animal health and reduced mortality rates.
Cooling Towers in Food Processing Plants
- Significantly lower chemical consumption vs. sodium hypochlorite, saving costs.
- Reduced corrosion risk, prolonging equipment life.

Comparing ClO₂Sure to Traditional Methods

Sodium Hypochlorite vs. ClO2 Sure

Odour & Taste: Traditional chlorine can give water a strong “bleach” smell; ClO2 Sure significantly reduces these issues.
Corrosion Risk: Lower oxidative stress on metals and plastics—ideal for prolonged use in large-scale systems.
pH Limitations: Chlorine quickly loses potency at higher pH; ClO2 Sure remains effective across a broader pH range.

Conventional Two-Part Chlorine Dioxide Generator vs. ClO2Sure

One Drum, One Step: Conventional Chlorine Dioxide dosing systems or generators often require mixing or oxidising multiple precursors on-site; ClO2Sure is single-chemical for a safer, more efficient process.
Reduced By-Products: ClO2Sure’s equilibrium mechanism suppresses chlorite and chlorate build-up, a common regulatory concern.
No Gas-Off Hazards: Because ClO2Sure stays fully in the liquid phase, there’s no risk of harmful gas release—lessening Health & Safety burdens.

An Alternative to Chlorine for System Cleaning & Chlorination

Comparable or Better Results with Lower Doses

Whether performing clean and chlorination tasks or maintaining daily disinfection, ClO2Sure offers similar—and often superior—results compared to conventional chlorine dosing (e.g., sodium hypochlorite). Its higher oxidative efficiency lets you use fewer chemicals, effectively managing or even surpassing your normal chlorine results.

Reduced Material Degradation

High doses of sodium hypochlorite can corrode metals and degrade plastic components, raising maintenance and replacement costs. By contrast, ClO2Sure’s equilibrium-based chemistry lessens corrosive impact, extending the lifespan of pipework, heat exchangers, and other critical infrastructure. This peace of mind about system integrity is another reason to swap out traditional chlorine in favor of ClO2Sure.

Key Benefits for Legionella Control & Biofilm Removal

Rapid Oxidation: ClO2 Sure immediately attacks legionella bacteria and disrupts biofilms.
Long-Lasting Residual: Regenerating chlorine dioxide maintains a continuous disinfectant presence.
Hospital & Healthcare Friendly: Excellent for high-stakes environments that demand top-tier hygiene.
Eco & Cost-Conscious: Lower chemical use means smaller environmental footprint and reduced spend.

Regulatory Compliance & Peace of Mind

Approved for Potable Water (PT5)

Because ClO2Sure is classified under Product Type 5 (drinking water) in the Biocidal Products Regulation, it meets rigorous standards for human consumption. Whether for offices, hospitals, or residential buildings, you’ll rest easy knowing your system is compliant.

Meeting UK Water Fittings Regulations

Inside premises, water must maintain its quality under the Water Supply (Water Fittings) Regulations 1999. Though there’s no strict statutory limit for in-building chlorine dioxide, you must verify that it stays within safe residual levels and that the water remains wholesome.

Easy Integration & Monitoring

Simple Dosing: No elaborate generation apparatus required—just dose and go.
Residual Checks: Measure free chlorine or use a surrogate parameter to confirm compliance.
Audit Records: Keep logs of dosage, test results, and inspections for complete peace of mind.
