Water softeners are high technology equipments which remove amounts of
excess minerals like calcium and magnesium from water, making it soft.
It is used to remove ions that cause hardness in water. The process
involves using ion exchangers, designed to remove ions, which are
positively charged. Water softeners mainly remove calcium and magnesium
ions and sometimes may also remove iron ions. These machines use sodium
as the exchange ion and are supplied from dissolved sodium chloride
salt. The core of a water softener is a mineral tank, filled with
polystyrene beads or resin carrying negative charge. Since minerals like
calcium and magnesium carry positive charge, they are attracted and
absorbed by the negatively charged beads, as the hard water passes
through the tank. Synthetic resin beads or natural zeolites act as the
exchange medium. Hardened minerals are collected in a conditioning tank
and flushed out from time to time.Application of Water Softeners
