Patent ID: 7264735

Claim:
A method for producing drinking water having a reduced cluster width and being capable of emitting FIR (Far Infrared Rays) energy by using a solution derived by chemical treatment of a charge generating material comprising the steps of: mixing and dissolving 40 to 50 wt % of distilled water, 2 to 3 wt % of 98% sodium hydroxide, 0.06 to 0.08 wt % of 98% calcium hydroxide in a reactor; adding 2 to 3 wt % of charge generating material in the form of powder of 500 mesh or more to the reaction, followed by stirring at 1000 to 2000 rpm for 30 to 60 minutes; adding 0.4 to 0.8 wt % of ferrous chloride and 3 to 5 wt % of ferric chloride to the reaction, followed by stirring at 1000 to 2000 rpm for 60-120 minutes until the blue reaction becomes completely brown color; settling the reaction for 10 to 15 hours, followed by addition of hydrochloric acid to pH 7 for neutralization; adding 40 to 50 wt % of distilled water to the neutralized reaction, followed by stirring for 30 to 60 minutes; and settling the stirred reaction for 24 to 36 hours, removing the clear supernatant from the reactor and distilling the supernatant with 0.1 to 0.3 wt % of active charcoal powder.
