Gachon University
  1. 1. Research Institution: Department of Chemistry, Gachon University
  2. 2. Experimental Period: January 30, 2007 – November 30, 2007 (305 days)
  3. 3. Research Objective: To evaluate whether the PH7.4 purification system can remove harmful substances from tap water and provide the conditions of healthy water.
Experimental Results
  • Harmful substances and bacteria were not detected in the control comparison.
  • Harmful heavy metals were almost completely removed.
  • Mineral preservation was excellent, especially with Pocheon granite.
  • Among granite samples, Pocheon granite showed the highest mineral activation effect, with an energy absorption value of 17,540.5 J/g-water.
  • It showed a favorable mineral balance, including major minerals such as Ca > Na > Mg > K, similar to natural spring water.
  • The water quality was closest to that of natural mineral spring water, and its composition was considered highly suitable for drinking.
  • The ionized mineral energy from Pocheon granite was estimated to generate beneficial wave energy in the range of 1.14 × 10¹³ ~ 5.64 × 10¹³ Hz.
  • The energy concentrated in the water molecules was estimated at approximately 4.71 × 10⁻²⁰ erg, suggesting efficient energy transfer within the water.
