During the treatment process the water gets through the mul-
tiway valve by the entrance connection, flows to the upper part
of the softener through the distributor producing this way an
ionic exchange inside the resin bed.
The treated water is collected by the distributor and driven
through the inner tube through the vessel till the multiway val-
ve. It is sent with the out connection till the main water pipe for
consumption. In this point the system has a counter for treated
water to be contabilized.
2.3 Regeneration of the system
The quantity of the calciun and magnesium ions that the resin
can keep is limited so the volume of water that a softener can
treat is also limited. Because of this the system has to do from
time to time a process known by regeneration that allows the
resin to be charged again with sodium ions in order to be able
to make the softening process again.
In Denver systems the regeneration process starts automati-
cally when the systems detects that the exchange capacity is
going to finish, the timer incorporated in the system allows to
configurate in a different way the starting of the regeneration,
please see section 6.3 in order to get more information about
how the programme works.
The regeneration of a softener system is made of different
parts, each with a concrete finality
BACKWASHING:
The water gets into the vessel through an inferior collector,
making a washing and a floffing of the resin bed and
allowing, this way, the following regeneration process.
ASPIRATION OF BRINE:
Through an aspiration process for venturi effect the system
suctions the brine liquid solution previously prepared for the
regenerating tank. This salt solution is introduced into the sof-
tening vessel getting in contact with the ionic exchange resin
and starting the regeneration.
SLOW RINSE:
It refers to the movement in the resin bed of the salt solution
previosly aspirated, this way the contact of the salt with the
resin is higher and the regeneration of the same is optimized.
FAST RINSE:
The water flows through the resin bed making a final wash of
the same and ensuring the total removing of the salt that can
be inside the vessel.
LLENADO DEL DEPÓSITO:
The volume of water goes automatically to the brine tank in
order to prepare the necessary brine to be consumed in the
next regeneration.This process is automatic, so normally it is
not necessary to put more water in the brine tank (except du-
ring the starting up as shown in section 7.
