Slightly Acidic Electrolyzed Water (SAEW) Generator
Slightly Acidic Electrolyzed Water (SAEW) Generator or hypochlorous acid generator is an electrochemical device designed to produce acidic electrolyzed water, a highly effective, eco-friendly disinfectant and cleaning agent.
In the treatment of medical wastewater, the core function of such equipment is to process the pollutants in the medical wastewater through the generated SAEW. Medical wastewater contains a large number of pathogenic microorganisms (such as bacteria, viruses, fungi, etc.), organic matter and some chemical residues. If not treated properly, it can easily cause public health risks. The hypochlorous acid and other components in SAEW can achieve efficient sterilization by destroying the cell membrane structure and protein molecules of pathogenic microorganisms.

Features Of SAEW Generator
01 Non-toxic residue
The decomposition products are water and trace amounts of chloride, and no carcinogenic trihalomethanes (THMs) are generated (a pain point of traditional chlorine disinfection).
02 Low corrosiveness
pH 5.0-6.5 is close to neutral, and its corrosiveness to pipelines and equipment is much lower than that of strong acidic disinfectants (such as chlorine dioxide).
03 No chemical storage and transportation risks
Production is carried out on-site as needed, avoiding the transportation and storage hazards of hazardous chemicals (such as liquid chlorine).
SAEW vs. AEOW Generators
The functional configuration is similar to that of an Acidic Electrolyzed Oxidizing Water (AEOW) generator, complying with GB28234-2020 Safety and Health Standards. The main differences are as follows:
| Items | SAEW Generator | AEOW Generator | |
| Whether the electrolyzer has a diaphragm or not | No | Yes | |
| Characteristics and Physicochemical Indicators(Produced Water) | Characteristics | Colorless transparent liquid with slight chlorine odor | Colorless transparent liquid with slight chlorine odor |
| Main Ingredients | Hypochlorous (HCLO), effective chlorine content of 40 ~ 80mg / L | Hypochlorous (HCLO), effective chlorine content of 50～70mg/L | |
| pH Value | 5～6.5 | 2～3 | |
| Oxidation Reduction Potential (ORP) | ≥600mV | ≥1100mV | |
| Residual Chlorine Ions | ＜1000mg/L | ＜1000mg/L | |
