Patent ID: 8663444

Claim:
A reduced water producing apparatus for producing reduced water from raw water including a metallic mineral, the apparatus comprising: a processing tank which contains the raw water including the metallic mineral, wherein the processing tank has a processing zone, an inlet zone that communicates with the processing zone via an inlet weir, and an outlet zone that communicates with the processing zone via an outlet weir; an electromagnetic water processing apparatus which produces the reduced water from the raw water, the electromagnetic water processing apparatus being located in the processing zone of the processing tank and being at least partially immersed in the raw water contained in the processing tank, the electromagnetic water processing apparatus comprising a transport pump having a first water inlet for receiving raw water from the processing tank and also having a water outlet, a water processing unit having an a gas inlet for supply of hydrogen gas to the water processing unit, a second water inlet connected to the water outlet of the transport pump, and an outlet for discharging water into the processing tank; a circulation pump which is in fluid communication with the processing tank and circulates the raw water through the electromagnetic water processing apparatus in the processing tank, the circulation pump being connected to a conduit for delivering water from the outlet zone to the inlet zone without passing through the processing zone; and a storage tank which stores the produced reduced water therein, the storage tank being connected to the processing tank, wherein the water processing unit is provided with an electromagnetic portion through which the raw water and the hydrogen gas pass, wherein the electromagnetic portion processes the hydrogen gas to make gas bubbles and to ionize the hydrogen gas, and wherein the reduced water is discharged from the electromagnetic water processing apparatus into the processing zone on the processing tank.
