water forms scale when heated, precipitates with an increase
in pH and reacts with soap to form an insoluble scum.
Most industries that use water have a need to properly
condition that water by softening it (removing calcium
and magnesium ions).
primary difference between an industrial softener and
a residential softener is that industrial systems often
operate 24/7 and must be sized to handle much larger volumes
of water for longer periods of time between regeneration
cycles. The systems are larger and flow more slowly per
cubic foot of exchange media than do residential systems.
They do, however, often use the same resins and grades
of salt for regeneration.
put this in perspective, a residential unit designed to
run at flows of 10 gpm still only sees a household usage
of around 300 gpd. A 10 gpm industrial system, running
just one eight hour shift processes almost 5000 gallons
and must be designed for continuous operation using a
twin system (so there is no down time). In addition, many
industrial uses require that the level of hardness be
reduced to less than 1 ppm of residual hardness whereas
residential users are often happy with 15 to 25 ppm.
systems generally require additional monitoring and testing
to insure that required hardness levels are not exceeded.
