Slightly Acidic Electrolyzed Water: From Application Scenarios to Electrolysis Anode Selection Guide

I. What Is This Disinfectant Water

Slightly Acidic Electrolyzed Water is an acidic aqueous solution with hypochlorous acid as the main bactericidal component. It is produced by adding softened water to low concentration hydrochloric acid and sodium chloride and electrolyzing in a diaphragm free or diaphragm electrolyzer.

Key chemical characteristics:

Parameter	Typical Range
pH value	5.0 – 6.5 (slightly acidic)
Available chlorine concentration	10 – 60 ppm
Main bactericidal component	Hypochlorous acid (HOCl)
Other components	Chloride ions, sodium ions, water

Hypochlorous acid has approximately 80 times the bactericidal efficiency of hypochlorite ions (OCl⁻), which is the chemical basis for the strong disinfection capability of slightly acidic electrolyzed water.

II. Technical Evolution: From Instability to Large-Scale Production

In the past, the instability of hypochlorite was a major technical obstacle to its widespread adoption. Hypochlorous acid easily decomposes, leading to reduced disinfection effectiveness and short storage periods.

Recent technological breakthroughs:

With the progress of electrolysis technology, the technical challenges caused by the original instability of hypochlorite have been overcome. Currently, the industry has achieved:

Large-scale production of stable slightly acidic electrolyzed water

Preparation of high-purity hypochlorite

Controllable pH value and available chlorine concentration

Extended effective storage time of electrolyzed water

This technological progress has made it possible for slightly acidic electrolyzed water to move from the laboratory to large-scale commercial applications.

III. Application Scenarios: Where Is It Being Used

Slightly acidic electrolyzed water has gained widespread application in the healthcare field due to its safety, high efficiency, and residue-free characteristics.

Human body disinfection applications:

Application Scenario	Specific Use
Oral disinfection	Mouth rinsing, oral wound cleaning
Damaged skin disinfection	Small wounds, abrasions, bed sore cleaning
Hand disinfection	Healthcare worker hand hygiene, public hand disinfection
Body surface disinfection	Preoperative skin preparation, postoperative wound care

Medical environment disinfection applications:

Application Scenario	Specific Use
Dental chair pipelines	Dental treatment unit waterline system disinfection
Ward departments	Air spraying, floor wiping, object surface disinfection
Medical appliances	Non-critical instrument soaking disinfection
Medical waste areas	Waste temporary storage areas, transport equipment

Other applicable locations:

Schools and kindergartens (hand disinfection and environmental disinfection)

Food processing workshops (surface disinfection)

Public transportation vehicles (interior disinfection)

Farms (disinfection and epidemic prevention)

IV. Electrolyzer Types: Diaphragm Free vs. Diaphragm Electrolyzer

Slightly acidic electrolyzed water production equipment is mainly divided into two electrolyzer configurations:

Electrolyzer Type	Structural Characteristics	Product Characteristics
Diaphragm free electrolyzer	Anode and cathode in the same chamber, no diaphragm required	Anode and cathode products mix, directly generating slightly acidic electrolyzed water
Diaphragm electrolyzer	Anode and cathode separated by a diaphragm	Anode chamber and cathode chamber products are separated and can be collected individually

Each configuration has its applicable scenarios. Diaphragm free equipment has a simple structure and lower cost, suitable for small to medium on-site preparation. Diaphragm equipment enables more precise product control, suitable for large-scale or specific purity requirement production.

V. Role of the Anode in the Equipment

During the generation of slightly acidic electrolyzed water, the anode undertakes critical chlorine/oxygen evolution reactions, directly affecting:

Generation efficiency and concentration of hypochlorous acid

Energy consumption level of the electrolyzer

Long-term operational stability of the equipment

Service life and replacement frequency of the anode itself

Therefore, selecting a compatible titanium anode is an important step in the design and manufacturing of electrolyzed water equipment.
