Method and apparatus for purification and activation of water

DETAILED DESCRIPTION The foregoing objects are attained, according to the present invention, by utilizing a method and apparatus whereby city running water or other kind water is passed and, if necessary recycled, through dechloration zone, activation zone then settlement zone successively.
Each zone is in the form of a cylindrical column of the same diameter and the three zones are usually united with connection means to an unit.
As the dechloration zone is to adsorb free chlorine and to decompose combined chlorine of water it is essential for water such as city running water which is chlorated but not always for other water.
In the dechloration zone an agent in porous granular form having an ability to decompose combined chlorine to free chlorine and to adsorb free chlorine such as calcic ceramics is charged.
For this purpose, for an example, calcic ceramic which is obtained from shells of a shell animal such as shell-fish by treating them at ultrahigh temperature according to conventional method may be also used.
The activation zone consists of charged particles of magnetic multielementary mineral i.
e.
macrocrystalline granite porphyry commonly called Elvan ("Bakuhanseki" in Japanese name) and magnet bars being installed longitudinally among said particles.
water is, while staying in the activation zone, disordered with its equilibrium state and ionized thereby to be activated.
The water exhausted from the activation zone will be neutral or weak-alkaline and rich in minerals.
The settlement zone is to disturb the ionic balance of water which is given by the activation zone and to make water oriented to be softened.
In the settlement zone plural numbers of magnet ball are charged.
The water exhausted from the settlement zone will be absolutely clean, fungi-free, and mild, and also accompanied with agreeable taste and odor.
The thus finally obtained water becomes close to natural mineral water and willingly acceptable as daily-life water to drink.
The temperature for treatment of water in any zone is not particularly limited but is preferred to be room temperature or little higher particularly for attaining sufficient activation of water in the activation zone
