Abstract
Abstract A method and an apparatus for purification and activation of water not only from a water purification plant but also from other sources by passing water through dechloration zone, to eliminate chlorine ion, activation zone to disorder the equilibrium state of water and ionize the water and settlement zone to disturb the ionic balance of the ionized water and make it oriented to be softened successively.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
92 words
An apparatus for purification and activation of water which comprises dechloration zone charged with an agent having an ability to decompose combined chlorine to free chlorine and to adsorb free chlorine, activation zone to disorder the equilibrium state of water and ionize the thus disordered water wherein particles of magnetic multielementary mineral and one or more magnet bars containing magnets in a midair space are installed among said particles and settlement zone charged with a means to disturb the ionic balance of water and to make the water oriented to be softened.
Claim 2
Independent Claim
92 words
An apparatus for purification and activation of water which comprises dechloration zone charged with an agent having an ability to decompose combined chlorine to free chlorine and to adsorb free chlorine, activation zone to disorder the equilibrium state of water and ionize the thus disordered water wherein particles of magnetic multielementary mineral and one or more magnet bars containing magnets in a midair space are installed among said particles and settlement zone charged with a means to disturb the ionic balance of water and to make the water oriented to be softened.
Claim 3
Dependent Claim
24 words
An apparatus according to claim 1, wherein the means is a magnet ball of a spherical body having a midair structure containing magnet pellets.
