How is Kangen Water Made? The Complete Electrolysis Guide

5 min read

In Japan, Kangen water has been used in hospitals for over five decades for its purported health benefits. This unique alkaline water is not drawn from a special spring, but rather created from your home's tap water using an advanced water ionizer machine and a process known as electrolysis. The transformation from regular tap water to hydrogen-rich, ionized Kangen water involves filtration, separation, and pH adjustment, all within a single device.

Quick Summary

Kangen water is produced from tap water using an Enagic water ionizer. This process involves filtering impurities from the water, followed by electrolysis which separates the water into alkaline and acidic streams. The resulting alkaline water is hydrogen-rich with a negative oxidation-reduction potential (ORP).

Key Points

  • Electrolysis Process: Kangen water is made using an Enagic ionizer that electrically separates tap water into alkaline and acidic streams.

  • Initial Filtration: The process begins by filtering tap water to remove impurities like chlorine and sediment, while retaining beneficial minerals.

  • Molecular Hydrogen: The electrolysis infuses the alkaline water with dissolved molecular hydrogen, a powerful antioxidant.

  • Negative ORP: The resulting alkaline water has a negative Oxidation-Reduction Potential (ORP), indicating its antioxidant capacity.

  • Multiple Water Types: Kangen machines produce a range of water types, from strong alkaline and acidic for cleaning, to neutral water for medications.

  • Differs from Bottled Water: Unlike bottled alkaline water, which is often chemically altered, Kangen water is electrically ionized and contains dissolved hydrogen.

The Science Behind the Kangen Water Production Process

Kangen Water, which means “return to origin” in Japanese, is produced by a specific type of machine that employs a technological process combining advanced filtration and electrolysis. This differs significantly from simple filtration and is the core of how the final product is created. The following steps outline the journey your water takes inside a Kangen machine.

1. The Initial Filtration Stage

Before any ionization can take place, the water must first be cleaned. Tap water enters the Kangen machine and passes through a high-quality, multi-stage filter. This internal filter is designed to remove common contaminants and impurities.

  • Removes Chlorine: Eliminates the taste and odor of chlorine, a common disinfectant in tap water.
  • Traps Harmful Substances: Removes rust, sediment, lead, and other undesirable particles to produce clean, fresh-tasting water.
  • Retains Minerals: Unlike some purification methods that strip the water of everything, this filter is engineered to keep beneficial minerals like calcium, magnesium, and potassium, which are essential for the electrolysis process.

2. The Electrolysis Process

After filtration, the now-purified water flows into the heart of the machine, the electrolysis chamber. This chamber contains multiple platinum-coated titanium electrode plates separated by an ion-permeable membrane. A small electrical current is passed through the plates, causing a chemical reaction called electrolysis.

  • Splitting Water Molecules: The electrical current causes the water ($H_2O$) to split into hydrogen ions ($H^+$) and hydroxide ions ($OH^-$).
  • Creating Alkaline and Acidic Streams: The chamber's design and charged plates guide the ions into two separate streams. The negatively charged cathode attracts positively charged minerals and forms the alkaline, hydrogen-rich Kangen water. The positively charged anode attracts negatively charged minerals and produces the acidic water.
  • Generating Molecular Hydrogen: The electrolysis process also generates a high concentration of dissolved molecular hydrogen ($H_2$) in the alkaline stream. This molecular hydrogen is a key component and powerful antioxidant touted for its potential health benefits.

3. Separation into Multiple pH Levels

The Kangen machine's key feature is its ability to produce different types of water with a range of pH levels for various uses. The user simply selects the desired pH, and the machine adjusts the electrical current and flow to produce the specified water type.

  • Kangen Drinking Water (pH 8.5-9.5): For daily consumption and cooking.
  • Neutral Water (pH 7.0): Purified water for taking medications or preparing baby formula.
  • Beauty Water (pH 4.0-6.0): Slightly acidic water with astringent properties for skin and hair care.
  • Strong Kangen Water (pH 11.5): Powerful dissolving properties for cleaning or washing pesticides off produce.
  • Strong Acidic Water (pH 2.5): A potent disinfectant for sanitizing surfaces and hands.

Kangen Water vs. Bottled Alkaline Water

Understanding the manufacturing process of Kangen water highlights the key differences between it and pre-packaged alkaline waters on the market. The comparison table below details the distinctions.

Feature Kangen Water (Machine-Produced) Bottled Alkaline Water
Creation Method Electrolysis, an electrical process that restructures water molecules. Chemical process, where minerals (like baking soda) are added to raise the pH.
Antioxidant Potential High negative Oxidation-Reduction Potential (ORP), indicating a high concentration of antioxidants. Typically has a positive ORP, meaning it lacks antioxidant properties.
Hydrogen Rich Rich in dissolved molecular hydrogen ($H_2$), a key antioxidant. Generally does not contain dissolved molecular hydrogen.
Stability Less stable and may revert to a neutral state over time, requiring prompt consumption. Stable, and its alkaline properties do not dissipate over time.
Cost High initial investment for the machine, but lower long-term cost per gallon. Lower initial cost per bottle, but higher long-term cost, and creates plastic waste.
Eco-Friendliness Reduces plastic bottle waste significantly. Contributes to plastic bottle waste.

Maintaining a Kangen Water Machine

Proper maintenance is crucial for the longevity and performance of a Kangen machine. Users need to perform certain routines to ensure the machine continues to function correctly.

  • E-Cleaning Cycle: After 15 minutes of use, or when the machine indicates, a cleaning cycle runs to prevent mineral buildup.
  • Running Neutral Water: It's important to run neutral water through the machine after producing strong acidic water to prevent plate damage.
  • Deep Cleaning: Enagic recommends a professional deep clean once a year to remove stubborn calcium deposits.

Conclusion

The process of how Kangen water is made is far more involved than simply filtering water; it is a sophisticated, multi-stage process that relies on advanced electrolysis technology. By using a Kangen machine, tap water is filtered, ionized, and separated into streams of varying pH levels, producing alkaline, hydrogen-rich water for drinking, along with other water types for various household purposes. This electrical transformation results in a product with a distinct negative ORP and dissolved molecular hydrogen, qualities that differentiate it significantly from standard water and chemically-altered bottled alkaline products. The initial investment in a machine provides a long-term, eco-friendly solution for those seeking the unique properties of Kangen water directly from their tap.

The Kangen Manufacturing Advantage

While the market offers several water ionizers, Enagic, the manufacturer of Kangen machines, highlights its advanced technology and medical-grade certifications as differentiators. The company claims its platinum-coated titanium plates and electrolysis process produce a more stable, higher quality ionized water compared to competitors. The creation of multiple water types, from strongly alkaline to strongly acidic, provides a versatile, all-in-one solution for household water needs, from drinking to cleaning. This comprehensive system is at the core of what defines how Kangen water is made and why it stands out from other water treatment options. The process offers a unique pathway to accessing specialized water types on demand, directly from the user's faucet.

Considerations and Scientific Context

While enthusiasts promote Kangen water for its health benefits, it is important to understand the scientific context. The core process is electrolysis, a standard chemical procedure. However, some of the more advanced claims, such as 'micro-clustering,' have been disputed by the wider scientific community as marketing terminology without significant medical backing. Moreover, some health benefits are supported by anecdotal evidence rather than extensive peer-reviewed studies specifically on Kangen water itself. It is always recommended to consult a healthcare professional regarding specific health claims. The process of how Kangen water is made is a verifiable chemical reaction, but the extent of its purported health advantages is a more complex topic that continues to be a subject of discussion. For an objective view on water ionization, general scientific literature should be consulted.

The Environmental Benefit of On-Demand Production

Beyond the water's properties, the production method itself offers an environmental advantage. By producing specialized water types at home, Kangen machine users drastically reduce their reliance on single-use plastic water bottles. This contributes to a more sustainable lifestyle and helps minimize plastic pollution that damages ecosystems. This environmental benefit is a direct result of the on-demand creation process, which eliminates the need for bottled alkaline water and the associated waste.
