1. What is Chlorine Dioxide Solution?
Chlorine dioxide is a yellow-green gas that dissolves easily in water to form a stable solution. It is known for its strong antimicrobial activity against:
- Bacteria
- Viruses
- Fungi
- Biofilms
Unlike chlorine (Cl₂), chlorine dioxide works through selective oxidation, meaning it does not chlorinate organic compounds. This significantly reduces the formation of harmful disinfection by-products such as trihalomethanes (THMs).
2. Traditional vs. Modern Preparation Methods
Traditional Chemical Method
The conventional way to generate chlorine dioxide involves reacting sodium chlorite with an acid:
While effective, this method has several drawbacks:
- Requires chemical activators (acids)
- May generate unwanted by-products
- Less precise control over concentration
- Higher handling risks
Modern Electrolytic Method (Recommended)
A more advanced and safer approach is electrolytic generation, which uses electricity instead of chemical activators.
3. Electrolytic Reaction Principle
In the electrolytic method, sodium chlorite (NaClO₂) dissolved in water is converted into chlorine dioxide through a controlled electric current.
A simplified reaction is:
How It Works
- Sodium chlorite is dissolved in water to form an electrolyte solution
- A precise electric current is applied
- Oxidation at the anode produces chlorine dioxide
- The process occurs in a controlled environment to ensure purity
The reaction uses only sodium chlorite and water, eliminating the need for acid activation.
Our Electrolytic Technology
Our generator works by means of an electrolytic method that decomposes sodium chlorite with a precise electric current, allowing the direct and pure production of chlorine dioxide without generating by-products or requiring chemical activators.
