HISTORY Mildly acidic water is produced from water ionizers, which use the process of electrolysis. Acidic water is produced at the positive electrode (anode). The Japanese Ministry of Health, Labor, and Welfare (JMHLW) approved this water in 1965, as an astringent for beauty purposes.1 The JMHLW also approved the alkaline and strongly acidic waters as medical substance. CLAIMED BENEFITS OF…
BRIEF HISTORY Electrolyzed reduced water (ERW) is the most common term in the scientific literature.1ERW has an alkaline pH (8-10) and contains molecular hydrogen.1Water ionizers were invented in the early 1900’s. Research on electrolyzed water started around 1931 in Japan where it gained popularity in the 1950’s.2 Around this time, the water was touted as having “healing effects”…
MILDLY ALKALINE IONIZED WATER Mildly alkaline water (pH 8-10) is marketed as healthy drinking water.1 It is produced from water ionizers via electrolysis.2Alkaline water containing molecular hydrogen is produced at the negative electrode (cathode).3 There are many names given to this water including: alkaline water,4 ionized water,5 alkali ion water,6 cathodic water,7 electrolyzed reduced water,9 and many more. Electrolyzed reduced water (ERW) is the most…
DEFINITION Electrolysis is simply using electricity to cause the decomposition of water (H2O) into hydrogen gas (H2) and oxygen gas (O2).1 Electrolysis was discovered in 1800 by Anthony Carlisle and William Nicholson2 and is now the primary method of mass-producing hydrogen gas for energy.3 SIMPLE EXPLANATION Electrolysis of pure water is very difficult,4 but adding only a…
Water ionizers are marketed for commercial and home use. These devices use a process called electrolysis1 to produce four main types of electrolyzed waters called functional waters.2 Figure 1. Depiction of a typical water ionizer connected to a tap water, producing acidic and alkaline water. MEDICAL DEVICE In 1965, the Japanese Ministry of Health, Labor, and Welfare (JMHLW) approved water…
On the market there are currently two main methods to obtain hydrogen-rich water via electric flow-through systems; namely, alkaline water ionizers and neutral-pH hydrogen water generators. A brief discussion of some of the pros and cons are noted below. ALKALINE WATER IONIZERS This technology has been around for many decades. It uses a process of electrolysis to produce hydrogen gas…
HYDROGEN GAS IN THE WATER The manner in which hydrogen gas is dissolved in the water has an effect on its stability and rate of exsolution (coming out of solution) and dissipation. Hydrogen gas can exist in water as fully dissolved gaseous solutes, colloidal and suspension forms, as well as large macrobubbles that exit almost…
INTRODUCTION The concentration of hydrogen gas (H2) is often reported in molarity (moles/liter (M) or milimoles/L mM), parts per million (ppm), parts per billion (ppb) or miligrams per liter (mg/L). In dilute concentrations, 1 ppm is about the same as 1 mg/L and they are often used interchangeably. The molar mass of molecular hydrogen is…
WATER IMPORTANCE Water is the universal solvent;1 it can exist as a solid, liquid or gas.2 It is necessary for the functions of life3 and for life to function.4 Water is the life-giving fluid that is always at the heart of creation.5 Its presence supports life, and its absence brings death.6 Water in liquid state is the principle criteria for…
