with tablets and the size of the outlet weir. All of this is accomplished without the use of
complicated instruments, controls, or even electrical power.
The tablet feeders made by EIC can handle up to 50,000 gallons per day (GPD). Larger
capacities up to 500,000 GPD can be treated by using a by-pass arrangement. Smaller
capacities can be handled with smaller feeders.
Installation is by gravity feed. The inlet of the D-CHLOR Tablet Feeder is piped directly to
the chlorinated water outlet, or installed anywhere along the final discharge line. The outlet
of the D-CHLOR Tablet Feeder can free-fall into a ditch, trench, or a drop box connected to
a discharge pipe.
It is possible that overdosing of sulfite can cause an oxygen deficient environment in the
aquatic system. The extent to which this could occur will depend on the concentration
of sulfite that is dosed to the environment. Dissolved oxygen measurements should be
taken if sodium sulfite tablets are used.
