water consumption. The equipment control valve has a daily or weekly calendar (Monday to
Sunday) and you can program which of these days the machine should rinse.
2.1.2. Brine tank
The brine tank is designed to store Sodium Chloride NaCl (Salt Tablets). Inside there are several
components: a float inserted in a cylindrical tube and an overflow outlet. The float regulates the
amount of water in the reagent tank to be used during the regeneration cycle. The float level can be
adjusted, but it is not necessary to do so in normal operation. Normally the water level should be
about 1/3 of the height of the salt container. This is sufficient to dissolve part of the NaCl for the
regeneration cycle.
2.2.System operation
The operation of the equipment has two main basic
cycles - the service and regeneration (rinsing) cycle.
Service cycle
In the service cycle, water is fed to the control valve via
the raw water inlet, then flows into the filter tank from
above and flows through the filter material to purify the
water, and then flows back through the collector pipe to
the control valve and then to the consumers. During this
time, the reagent tank should contain water
approximately 1/3 of the height of the brine tank to
dissolve the Salt (NaCl) used to recover the filter media.
The duration of the service cycle depends on the quality
of the incoming water, the amount of filter material and
the amount of water consumed. If one of the consumers
uses water during the service cycle, "SOFTENING"
appears on the display of the CMS series models. The
WATEX CMS series has a built-in meter that counts the
amount of water consumed. With the help of the
electronic display, it is possible to set the volume of
water (m3) after which has been consumed the control valve starts regenerations. As soon as the
meter has counted the specified volume of water, the equipment will start at the regeneration the
same night. At 2.00 o clock (factory setting) the regeneration cycle is started. The start of the
regeneration cycle can be changed via the electronic display.
2.3.
Regeneration cycle schemes
The equipment requires a rinsing cycle to remove accumulated material from the filter and restore
the capacity of the filter media. The capacity of the filter material is expressed in m3, so the meter
built into the WATEX CMS model counts the amount of water consumed and after a certain
consumption of m3 the unit switches to the rinsing cycle. The rinsing cycle lasts approximately 1.5
hours and consists of several modes. The machine has 4 main modes: countercurrent rinsing, reagent
suction, to the consumers flow rinsing and filling the reagent tank. The order of the modes can be
changed on the control valve, but we recommend using the order of the modes already set at the
factory. To ensure a continuous supply of water to the consumers during the rinsing cycle, untreated
