THM-free pool disinfection systems
                     Sustainable Water Treatment 
Solutions
Greentech International delivers innovative 
THM-free pool disinfection systems and advanced Hydro Dioxide technology 
— supporting safer swimming environments, cleaner water quality, and a more 
sustainable future for commercial and public aquatic facilities across the UK.
GREENTECH INTERNATIONAL HYDRO DIOXIDE TECHNOLOGY
Why Choose THM-Free Technology?
Traditional chlorine-based disinfection creates trihalomethanes (THMs) — harmful chemical by-products linked to respiratory irritation, long-term health risks, and poor 
indoor air quality. THM-free systems eliminate these risks while maintaining powerful microbial control.
Eliminate Harmful By-Products Improved Air Quality
Prevents formation of THMs, reducing health risks for swimmers and staff. Reduces chloramine buildup in indoor facilities, improving respiratory comfort.
Superior Water Safety Reduced Chemical Load
Targets biofilms and chlorine-resistant pathogens for consistently clean water. Lower chemical dependency means less handling, storage, and disposal burden.
Supporting Net Zero Goals
Greentech International's Net Zero water treatment solutions are designed to help aquatic facilities reduce their carbon footprint 
without compromising water quality or operational performance. Our approach aligns with UK sustainability mandates and future 
regulatory expectations.
What Net Zero Water Treatment Means How Greentech Supports Your Goals
Net Zero water treatment focuses on minimizing energy • Reduced chemical consumption lowers embodied carbon
consumption, reducing chemical inputs, and lowering • High-efficiency dosing systems minimize energy use
greenhouse gas emissions across the full water treatment • Compatible with renewable energy-powered facilities
lifecycle — from dosing to discharge. • Supports ESG reporting and sustainability certifications
• Future-ready for tightening environmental regulations
Sustainable Wastewater Treatment
Facility managers face increasing pressure to reduce chemical discharge and improve environmental performance. 
Chlorine-free wastewater treatment technologies offer a cleaner, more responsible path — protecting local ecosystems while 
maintaining operational efficiency.
Cleaner Discharge Operational Efficiency Lower Environmental Impact
Chlorine-free systems significantly reduce Advanced treatment technologies Reduced chemical dependency means 
harmful residual chemicals in discharged streamline processes, reduce manual fewer hazardous materials on-site, lower 
water, protecting aquatic ecosystems and chemical handling, and lower total cost of transport emissions, and a smaller overall 
reducing compliance risk. ownership over the system lifecycle. environmental footprint.
Regulatory Compliance: GB BPR Standards
Choosing GB BPR compliant pool chemicals ensures your facility meets the UK's 
rigorous Biocidal Products Regulation standards — providing confidence in product 
safety, efficacy, and responsible chemical management. Non-compliance carries 
significant legal and reputational risk.
Product Safety Assured
All Greentech products undergo full GB BPR evaluation for human and 
environmental safety.
Performance Verified
Independent testing confirms disinfection efficacy at approved dosage levels.
Documentation Provided
Full compliance documentation and Safety Data Sheets supplied with every 
product.
Advanced Hydro Dioxide Technology
At the heart of Greentech offering is Hydro Dioxide technology — a next-generation disinfection solution that outperforms 
traditional chlorine while producing zero THMs. It is specifically engineered for the demands of high-traffic commercial and 
recreational water systems.
Target Biofilms Kill Resistant Pathogens
Penetrates and destroys biofilm layers that conventional Effective against chlorine-resistant organisms including 
chlorine cannot fully eliminate. Cryptosporidium and Giardia.
Reduce Chemical Load Deliver Consistent Results
Achieves superior results with significantly lower chemical Maintains stable water quality across varying bather 
input and reduced dosing frequency. loads and environmental conditions.
Environmental Benefits at a Glance
Combining Net Zero water treatment strategies with chlorine-free wastewater treatment creates a compounding
