Abstract
This invention relates to a method and apparatus for producing high pH water containing dissolved lime by forcing potable water through a column of powdered lime supported on a porous support without transporting significant quantities of lime out of the column. Two or more columns may be connected in parallel to permit recharging of one while the other remains on stream.
