Patent ID: 7476311

Claim:
A system for removing arsenic from a water source, the system in-line with a water treatment facility, the system comprising: a predetermined amount of ferric-loaded zeolite for absorbing arsenic from a predetermined volume from the water source; and a housing member for constraining the predetermined amount of ferric-loaded zeolite for contact with the water source, the housing operatively connected to the water treatment facility; wherein, the water source has a first level of arsenic before it contacts the predetermined amount of ferric-loaded zeolite and a second level of arsenic after it contacts the predetermined amount of ferric-loaded zeolite, the second level of arsenic lower than the first level of arsenic in the water source and wherein at least some of the water from the water source will be used as potable water; a second predetermined amount of ferric-loaded zeolite for absorbing arsenic from the water source after the water source has contacted the first predetermined amount of ferric-loaded zeolite; and a second housing for constraining the second predetermined amount of ferric-loaded zeolite for contact with the water source; wherein, the water source has a third level of arsenic after it contacts the second amount of chemically treated zeolite, the third level of arsenic lower than the second level of arsenic in the water source; and a predetermined amount of aluminum-loaded zeolite, mixed with the ferric loaded zeolite, for absorbing arsenic from the water source.
