We call water "hard" if it contains a lot of calcium or
magnesium dissolved in it. Hard water causes two
problems:
·
It can cause "scale" to
form on the inside of holding tanks, pipes, tea kettles and
so on. The calcium and magnesium precipitate out of the
water and stick to things like faucets and sinks, the side
of your boat, RV and dulls your glass or plastic boat top.
·
It also reacts with soap
to form a sticky scum, and also reduces the soap's ability
to lather so you use a lot more soap.
The solution to hard water is either to filter the water by
distillation or reverse osmosis to remove the calcium and
magnesium, or to use a water softener. Filtration
would be extremely expensive so a water softener is usually
a less costly solution.
The idea behind a water softener is
simple. The calcium and magnesium ions in the water are
replaced with sodium ions. Since sodium does not precipitate
out in pipes or react badly with soap, both of the problems
of hard water are eliminated. To do the ion replacement, the
water runs through a bed of small plastic beads or through a
chemical matrix called zeolite. The beads or zeolite
are covered with sodium ions. As the water flows past the
sodium ions, they swap places with the calcium and magnesium
ions. Eventually, the beads or zeolite contain nothing but
calcium and magnesium and no sodium, and at this point they
stop softening the water. It is then time to regenerate
the beads or zeolite.
Regeneration involves soaking the beads or zeolite in a stream of sodium ions. Salt is sodium chloride, so the water softener mixes up a very strong brine solution and flushes it through the zeolite or beads (this is why you load up a water softener with salt). The strong brine displaces all of the calcium and magnesium that has built up in the zeolite or beads, and replaces it again with sodium. The remaining brine plus all of the calcium and magnesium is flushed out during the brining process.
