These cationic ion exchange systems are designed
to remove calcium and magnesium (hardness), and a host of other
cations from the water. SWT takes care of the little extras such
as: machined PVC distribution systems, oversized brine tanks, safety
float for 16 inch or larger systems, and an anthracite underbedding.

In basic terms, crosslinkage refers to the resin beads physical strength or ability to withstand chemical attack from chlorine,
resin bed cleaners, and caustics used in DI applications. To a lesser extent, a higher crosslink also gives resin slightly
higher softening capacity and a better affinity for iron.
|
|
Almost all standard softening resins in the market range from 6.5% to 8% crosslink. If the water
softener is on a chlorinated system, or sitting outside where high temperatures can weaken resin, then lower crosslink
resins have a tendency to breakdown, lose capacity, and turn mushy over time . Generally speaking, the higher the crosslink,
the better (and more expensive) the resin. 10% crosslink resins are generally too expensive for residential use and are
found in mostly DI and industrial applications.
Fine mesh resins, which are smaller than standard size resin beads, slightly increase the softeners capacity, speed up
softening reaction time, and increases the ability to filter fine particles from the water supply. These are good for dual
bed systems because they help retain the smaller, lighter anion resin beads on the top layer. They are also popular in
cabinet style water softeners with shallower resin beds.
