The Village of Cary, Illinois, in McHenry County, is typical of many communities
in the area. Cary needed to increase their well supply capacity to meet rapidly
increasing demand due to population growth. Three years earlier, the Village had
stopped routine operation of two deep aquifer wells due to the presence of barium
in the water. Operation of one of the wells was begun once a water treatment
plant for the removal of barium had been constructed in the building adjacent to
the well. As the population continued to increase, the need for additional
sources of water remained acute. The Village was faced with two alternatives:
find a new well supply and construct a treatment facility to treat for either
barium (present in the deep aquifers) or iron (present in the shallow aquifers);
or construct a treatment facility at the existing well. However, a preliminary
investigation indicated that the construction of a conventional barium removal
treatment facility at the existing well site would necessitate acquiring adjacent
property. The answer was a unique combination of water treatment processes which
utilized the existing building. This not only reduced the projected construction
cost, which allowed the Village to remodel an aging facility for the budgeted
funds, but reduced the concerns of the residents in the area. This paper
discusses the design, construction and operation of Cary's new gravity ion
exchange softener.
