cation exchange softening resin
Hardness of water is the single most costly water quality issue faced by homeowners, businesspeople,
and public executives. Some of the symptoms of excessive water hardness are limescale deposition
inside water pipes and appliances, overuse of detergent, poor lathering of soap, compromised plumbing
xture appearance, overuse of electric power by water heating appliances, poor skin and hair condition.
Water hardness is produced by calcium and magnesium ions in the water. Ion exchange softening is
a simple and convenient way to address water hardness. Ion exchange resins attract and retain ions
of metals dissolved in water and release harmless ions of sodium to balance out the charge. When
ion exchange capacity of the resin becomes depleted, the resin has to be regenerated to restore its
properties. During regeneration, concentrated salt brine seeps slowly through the bed, allowing sodium
ions to displace and ush out ions of hardness.
Chemically, the process is described by reaction:
2RNa + Ca(HCO
3
)
2
= R
2
Ca + 2NaHCO
3
where R stands for ion exchange valency
Regeneration of the cation exchange resin with sodium chloride solution takes the resin back into Na+ form:
R

Ca + 2NaCl = 2RNa + CaCl

granular activated carbon systems
Granular activated carbon (GAC) is used for removing chlorine and chlorine compounds, natural organic
matter (humic substances), pollutants including petroleum products and pesticides, and improving
organoleptic properties of water.
Ecosoft FPA systems use Filtrasorb macroporous GAC well-suited for removal of organic impurities
found in natural raw water and chlorine removal. The media is regenerated by timer with backwash.

catalytic carbon systems
Centaur
®
catalytic carbon is used for correcting organoleptic properties of well water. It is particularly
e󰀨ective for removal of hydrogen sulde by catalytic oxidation and adsorption of the products.
It removes small concentrations of iron provided that surface ow will not exceed 10 m
3
/(h·m
2
), oxygen
concentration is in excess of stoichiometric demand, and pH is above 7. For e󰀨ective catalytic functioning,
Centaur requires dissolved oxygen concentration of at least 15% the mass of iron and 50% the mass
of H2S. Other oxidizing reagents can be injected in raw water to achieve the same desulfurization and
deironing e󰀩ciency. The media is regenerated by timer with backwash.

multimedia systems
Filter Ag® is a granular media that is used for reduction of suspended solids by removing particulate
matter. The media consists of irregularly shaped grains, which trap and retain waterborne particles
by straining and adhesion. Common applications of Filter Ag® systems include pretreatment of high
turbidity water, removal of pre-oxidized iron oc, silt and other types of suspended matter.
Filter Ag® bed is regenerated with backwash.
