The upflow counter-current filters have the following advantages as compared to
the downflow filters with, fixed bed namely : the spent carbon which is almost
always close to the filter bottom can easily be removed by gravity; and, as the ...
In a downflow saturator, the sodium fluoride rests on a filter bed of sand and
gravel at the bottom of a saturation tank. A deep layer of water is kept on top of
the fluoride. The water seeps down through the fluoride and is collected as a
saturated ...
