How to Reduce Chlorine Treatment Naturally
Maintaining a swimming pool involves a delicate balance of pH, chlorine levels, and overall water quality. For leisure centres, hotels, and pool operators, achieving crystal-clear, safe water while keeping operational costs under control is an ongoing challenge. Traditional pool maintenance requires constant chemical adjustments, but E-ACTI’WATER+ offers a smarter, more sustainable alternative—reducing chemical dependency while enhancing swimmer comfort and cutting costs.
Understanding pH and Chlorine in Pool Water
pH is a measure of how acidic or alkaline the water is, with an ideal range of 7.0 to 7.2. Keeping pH in this range is crucial because it determines how effectively chlorine works: (PWTAG TN52)
🔹 Low pH (below 7.0): Water becomes acidic, leading to corrosion of pool equipment, eye irritation, and rapid chlorine depletion.
🔹 High pH (above 7.6): Water becomes too alkaline, chlorine efficiency is reduced and causing cloudy water, limescale buildup, and potential bacterial growth.
Chlorine is the most widely used disinfectant in pools, responsible for eliminating bacteria, algae, and other contaminants. However, its effectiveness depends heavily on pH levels: When sodium or calcium hypochlorite is added to water, it forms two types of free chlorine: hypochlorous acid (HOCl) and hypochlorite ion (OCl-). HOCl is the stronger disinfectant. The amount of each depends on the water’s pH, so keeping the right pH is important for effective disinfection. DPD tests measure both forms together, so checking pH helps determine how much active free chlorine is available.
The graph and table below show how pH affects this balance (PWTAG TN60)
- At a pH of 7.0, chlorine is 75% effective.
- At a pH of 8.0, chlorine is only 25% effective, requiring higher doses to maintain sanitisation.
- At a pH of 6.5 chlorine is 90% effective, requiring lower doses to maintain sanitisation.
This imbalance often leads to excessive chemical use, increasing operational costs and exposing swimmers to harsh water conditions. Many countries throughout the world and particularly in Europe set a pH range of 6.5-7.3 and have provided excellent quality pool water for a long time. Modern pipe and operational equipment is mostly treated with protective lining, meaning a lower pH won’t corrode pool equipment.
How E-ACTI’WATER+ Improves Swimming Pool Water Naturally
E-ACTI’WATER+ is a innovative, chemical-free solution that enhances water quality without energy, chemicals, or ongoing maintenance. Our Activated Water—stabilises pH naturally, leading to better chlorine performance, more active free chlorine, improved water clarity and a much better experience for swimmers.
Key Benefits:
✅ Reduce Chlorine Use by up to 40% – E-ACTI’WATER+ improves chlorine efficiency, meaning less chlorine is needed to maintain sanitisation. This reduces chemical costs and lowers swimmer exposure to harsh chemicals.
✅ pH Stabilisation – The technology naturally balances pH levels, minimising the need for pH adjusters and reducing fluctuations that lead to excessive chemical corrections.
✅ No Longer Require Salt for Water Softening – The unique water activation process eliminates the need for additional salt or chemical softeners, helping extend equipment lifespan and reduce maintenance.
✅ Prevents Algae Growth & Limescale Buildup – By improving water structure we reduce the nitrates and phosphates that cause algae blooms, E-ACTI’WATER+ makes it harder for algae and limescale to form, reducing the need for algaecides and chlorine shocks.
✅ Water Feels Softer and More Natural – The result is a swimming experience closer to fresh natural spring water, with enhanced clarity and reduced irritation to skin and eyes.
✅ Lower Maintenance & Cost Savings – Pool operators benefit from fewer chemical purchases, less frequent maintenance, and prolonged equipment lifespan, ultimately reducing overall operating costs.
How E-ACTI’WATER+ Compares to Traditional Pool Treatment
| Feature | Traditional Pool Treatment | E-ACTI’WATER+ |
|---|---|---|
| Chlorine Usage | High (due to inefficiencies) | Up to 40% reduction |
| pH Stability | Requires constant adjustments | Naturally balanced |
| Salt/Softening Chemicals | Required for water softening | Not needed |
| Algae & Limescale Control | Requires additional chemicals | Prevents naturally |
| Water Feel | Can be harsh on skin/eyes | Feels like fresh spring water |
| Maintenance Costs | High due to chemical use & scaling | Lower costs, minimal maintenance |
A Smarter, More Sustainable Future for Pool Management
Traditional pool maintenance relies on constant chemical dosing and monitoring, leading to high costs, frequent maintenance, and potential discomfort for swimmers.
With E-ACTI’WATER+, leisure centres and pool operators can take a more natural, efficient, and cost-effective approach to water management.
✅ Reduce chlorine and other chemicals requirements by up to 40%
✅ Natural solution for hard water problems
✅ Lower operational costs and maintenance time
✅ Improve water quality and swimmer experience
For leisure centres looking to cut costs, reduce chemical reliance, and enhance water quality, E-ACTI’WATER+ is the future of sustainable pool management.
