A Safe and Effective Way to Disinfect Pools and Natural Ponds
In recent years, low-salt electrolysis, also known as hydrolysis, has become a popular method for disinfecting both swimming pools and natural swimming ponds (biopools).
Why Is Hydrolysis a Good Choice?
Hydrolysis transforms water into powerful natural disinfectants without the need for harmful chemicals. It operates by using electricity to split water (H₂O) into hydrogen (H) and oxygen (O) atoms. These atoms then form effective cleaning agents such as:
- Atomic oxygen (O)
- Oxygen gas (O₂)
- Ozone (O₃)
- Hydrogen peroxide (H₂O₂)
- Hydroxyl radicals (•OH)
These disinfectants are as strong as chlorine, if not stronger, but unlike chlorine, they don’t leave behind harmful by-products like chloramines. After disinfecting the water, these agents naturally revert to water.
Salt Levels and Use
- At salt levels of 1.5–2 grams per litre, the system also produces a small amount of chlorine, which provides a lasting disinfecting effect.
- For natural swimming ponds, where chlorine is not desired, it’s best to keep the salt level below 1 gram per litre.
- ⚠️ Important: This method is not suitable if your pond uses an EPDM liner.
How Does Hydrolysis Work?
Water comprises 2 hydrogen atoms and 1 oxygen atom (H₂O).
The term “hydrolysis” means “splitting water”.
When electricity passes through the water, it breaks apart the hydrogen and oxygen atoms. The oxygen ions move toward the positive electrode (the anode), initiating a series of reactions that produce additional cleaning agents.
These reactions release oxidising elements that help eliminate bacteria and other unwanted organisms in the water. This results in cleaner, safer, and more natural water—without relying on harsh chemicals.
Hydrolysis System Diagram
To better understand the hydrolysis process, here’s a simplified diagram illustrating the water treatment system:
Comparison of Oxidation Potentials
The effectiveness of disinfectants can be compared using their oxidation-reduction potential (ORP). Higher ORP values indicate stronger oxidising agents:
| Disinfectant | Oxidation Potential (V) |
|---|---|
| Hydroxyl radicals (•OH) | +2.80 |
| Ozone (O₃) | +2.07 |
| Hydrogen peroxide (H₂O₂) | +1.78 |
| Chlorine dioxide (ClO₂) | +1.50 |
| Chlorine (Cl₂) | +1.36 |
| Hypochlorous acid (HOCl) | +1.49 |
Note: Values are approximate and can vary based on conditions.
✅ Why Choose Hydrolysis for Your Pool or Pond?
Hydrolysis has several key benefits:
- Eco-friendly: Doesn’t rely on harsh chemicals
- Safe: No toxic residues
- Effective: Kills bacteria, algae, and other microorganisms
- Natural feel: Water remains soft and gentle on the skin and eyes
This makes it ideal for natural swimming ponds, especially in eco-sensitive areas like Kochi, Kerala, where chemical-free solutions are increasingly in demand.
🏊 Interested in Installing a Hydrolysis System?
This table demonstrates that hydroxyl radicals and ozone, both produced during hydrolysis, have higher oxidation potentials than traditional chlorine-based disinfectants, making them highly effective in water treatment.
At KJASons® and Bioponds, we provide custom water treatment systems for all types of pools and ponds across Kerala. Whether you’re building a new natural swimming pond or upgrading an existing pool, our team can help you design and install the perfect setup.
