1. PURPOSE

1.1. Overview
Ecosoft media systems are automatic water treatment appliances using bed filtration to
remove impurities. Ecosoft filters consist of the following main parts:
• pressure vessel made of fiberglass reinforced plastic
• automatic control valve mounted on the pressure vessel
• riser pipe, top and bottom distributors
• filter media
• (FK and FU systems only) brine tank with brine system
Ecosoft filters are used for treatment of household water, steam boiler and heating circuit
feed water, and other commercial and industrial water treatment processes. Different series
of Ecosoft filters are intended for removal of different types of impurities.
Pressure vessel size determines the quantity of filter media, flow capacity, and volume
capacity of the filter. When water passes through the filter, the filter bed accumulates
impurities that it works to remove. After using up the volume capacity of water, the material's
holding capacity or exchange capacity becomes exhausted and the filter stops removing
more impurities (or the pressure drop builds up to critical value). At this point, the filter must
be rinsed or brine regenerated to restore its capacity. Volume capacity depends on the
quantity of filter media and composition of raw water.
When exhausted, non brine regenerated filters are backwashed and then forward rinsed
to release the accumulated impurities. Brine regenerated filters undergo backwash, then
rinse with brine from the brine tank to release hardness ions from ion exchange sites, then
forward rinse and brine tank fill.
Ecosoft filters use the following naming conventions:
Type of system: FU, FK, FP, FPA or FPC
(described in the following section)
Pressure tank size: '12' inch diameter, '52' inch tank height
(first two digits indicate the diameter, second two digits indicate the height)
Control valve type: CE, CI, CT or DV
(described in the following sections)
