Hypochlorous Acid Generator


hypochlorous acid generator is producing hypochlorous acid solution by electrolysis 0.3% brine,  the core technology is the membrane electrolytic cell that have been designed innovative and unique technology to effectively deliver electrolyzed water solut


Hypochlorous acid generator is a system which is produced by electrolysis of tap water through water purification system and is produced by a special electrolytic cell. The system produce hypochlorous acid (HCLO) with pH (5~6.5), redox potential (ORP value +750mv or more) and available chlorine (50~60mg/L), also produce sodium hydroxide (NaOH) with PH (10~12), redox potential(ORP value -800~900 mv).

Principle of electrolysis

Hypochlorous acid generator electrolyzes 0.1% of NaCl solution in a special electrolytic module. In the advanced anion membrane, the acid oxidation potential water is generated from the anode side and the alkaline reduction potential is generated from the cathode side. Most of the alkaline water will enter the anode chamber twice, and after the second electrolysis, the slightly acidic electrolytic ion water will be generated from the anode side. A small amount of alkaline water will be generated from cathode side.

The slightly acidic water (HClO) produced by electrolysis diluted brine, with high redox potential and excellent germicidal ability, and it contains no chemical additives. The slightly acidic electrolyzed water is a solution with high safety, no residue and environmentally friendly.

Technical principle

Anolyte from anode

The main components of the anolyte are hypochlorous acid(HClO) and hypochlorite(ClO-), it also contain a small amount of hydrogen peroxide(H2O2) andhydroxyl groups(-OH). The hypochlorous acid solution decomposes to form a new ecological oxygen[O]. The new ecological oxygen has strong oxidative properties and  cause degeneration of proteins and other substances of bacteria and viruses, thereby killing pathogenic microorganisms.

Catholyte from cathode

The main component of catholyte is sodium hydroxide (NaOH) with 10~12 PH, -800~900mv ORP, which can effectively clean and disinfect the general surface, activate crop growth, or as a coagulation or flocculant (handling mild heavy metal pollution, or ingesting oily ingredients in the isolation solution, etc.), even replacing iodine to clean the wound, or properly adjust pH of liquid, etc.

When to use it

Where Used Effect
Sterilizing cut vegetables After cleaning, vegetables are sanitized and kept fresh for longer time: crisp and crunchy.
Sterilizing & sanitizing cutting board The cutting board cleaned with Slightly Acidic Electrolyzed Water can be kept clean without bacteria growth.
Hygienic management of pool Used for the water in public pools, it has outstanding sterilization effect and allows much reduced chlorine odor compared with the conventional sterilization method.
Sterilization and sanitization of plant facilities It is time-proven with more than 10 year`s experiences including large milk plants in Japan.

The advantage of HClO

1.Sterilization: The slightly acidic water(HClO) has low concentration, high activity, extensive antibacterial and antiviral activity. It has slight oxidizing ability and high efficient to kill microorganisms.

2. Safety: low toxicity, no tolerance to bacteria, no harm to human health.

3. Food related: reduce the rate of decay of food, deodorization treatment at the food processing industrial.

4. Easy operation: Use salt (NaCl) as electrolyte, diluted brine into the electrolysis cell to electrolysis, simple and safe for continuously manufactured.

5. Health management: a wide range of uses, cleaning and sterilization, spray sterilization. It can be used for surface disinfection, air disinfection, etc.

6. Low effect on food: no affect taste, color, smell or nutrients of food, low residue.

7. Compared with the currently used sodium hypochlorite or alcohol, the concentration is low and disinfect in a short time, which ensures safety. After sterilization, it can be completely reduced to non-toxic, non-residual ordinary water. The environment is non-polluting and has the characteristics of reducing costs and reducing environmental pollution load.

8. In the application of food, fruit and vegetable, it has high efficient, instantaneous sterilization ability. It can significantly reduce the amount of mold causing rot on the surface of the fruit, and also significantly inhibit the browning of fruits and vegetables. At the same time, it also has a certain regulation effect on physiological metabolism, which can effectively extend the shelf life of the fruit.

9. The slightly acidic water has the characteristics of safety, economic applicability, low operating cost, water saving, and wide use of objects.
