Why Choose the Electrochemical Chlorine Generator?

Handling and storing hazardous chemicals such as liquified gas chlorine or commercial bleach involves significant safety risks and operational challenges. The electrochemical chlorine generator, offered by EAI Water, provides a safer, more efficient alternative. This system is designed to generate pure chlorine gas or the highest purity sodium hypochlorite solution directly on-site, using only one non-hazardous precursor: granular salt or purified brine (solution of salt). By leveraging advanced electrochemical processes, this generator delivers chlorine at a very low operating cost, thanks to its high-efficiency electrolytic membrane cell.

Replacement of Bulk Bleach Storage – Enhanced Flexibility and Safety

Many facilities rely on frequent deliveries of commercial sodium hypochlorite (bleach) for water disinfection, which involves risks associated with unloading, storage, and dosing. Additionally, commercial bleach (12.5% sodium hypochlorite) degrades over time, leading to reduced effectiveness and increased chlorate formation. EAI Water’s generator offers a superior solution by producing sodium hypochlorite on-demand, with concentrations ranging from 2-30 g/L. This method not only minimizes degradation but also lowers the levels of sodium, chloride, and chlorate in the final product, ensuring more stable and effective disinfection.

Advantages of On-Demand Generation:

• Reduced Degradation: Unlike commercial bleach, which loses half its concentration within 20 days, the sodium hypochlorite produced by the generator remains stable with virtually no degradation over 90 days.
• Safety and Convenience: The system eliminates the need for large bulk storage tanks and the associated safety risks. It also offers flexibility, especially in remote areas where bleach deliveries are costly or unreliable.

Practical Applications: For sites that already have bulk storage tanks for 12.5% sodium hypochlorite, the generator can be used to top up these tanks, reducing reliance on tanker deliveries and ensuring a consistent supply of fresh sodium hypochlorite.

Chlorine Generation Process

The generator utilizes a sophisticated, efficient, and safe electrochemical process to produce chlorine, which is then converted into sodium hypochlorite. The chemical reactions involved are as follows:

1. Anode Reaction (Oxidation):
   2Cl–→Cl2+2e–2Cl^– → Cl_2 + 2e^–2Cl–→Cl2​+2e–
2. Cathode Reaction (Reduction):
   2H2O+2e–→H2+2OH–2H_2O + 2e^– → H_2 + 2OH^–2H2​O+2e–→H2​+2OH–
3. Combined Reaction:
   2Cl–+2H2O→Cl2+H2+2OH–2Cl^– + 2H_2O → Cl_2 + H_2 + 2OH^–2Cl–+2H2​O→Cl2​+H2​+2OH–

Final Product:

• In the HG Generator, chlorine gas reacts with caustic catholyte to form sodium hypochlorite and salt:
  Cl2+2NaOH→NaCl+NaOClCl_2 + 2NaOH → NaCl + NaOClCl2​+2NaOH→NaCl+NaOCl
