Cation Resin

Cation ion exchange resins may be light or dark in color. Color variation in new cation has no impact on its performance. For drinking water applications, Lanlang has WQA Gold Seal or NSF certified


Cation resins by type are:

Strong Acid Cation (SAC) resin are sulfonated copolymers of styrene and DVB.

Weak Acid Cations (WAC) have a polyacrylic backbone.

SAC and WAC resins are manufactured in different forms – macroporous and porous (gel).

Cation resins in the Na+ form will exchange sodium for the following ions:

Calcium (Ca++)

Magnesium (Mg++)

Iron (Fe++)

Manganese (Mn++)

In the H+ cation resin will exchange hydrogen for the following ions:

Calcium (Ca++)

Magnesium (Mg++)

Manganese (Mn++)

Iron (Fe++)

Sodium (Na+)




Anion Resin

Anion exchange resins are usually light in color. Color variation in new anion has no impact on its performance.



The most popular anion resins by type are:

Type 1

Type 1 anions (SBA-1) have the strongest affinity for weak acids but lower regeneration efficiency which equates to lower capacity.

SBA Type 1 macroporous anions are often used for organics or tannin reduction.

Regeneration is with brine making it suitable for residential purposes.

Nitrate selective SBA Type 1 macroporous anions are also available for nitrate reduction of potable water. (SBA-2 also removes nitrate but is not selective. It is commonly used where equipment operators are present.)

Higher regeneration efficiency is attained by increasing regenerant temperature for SBA-1.

Type 2

Type 2 anions (SBA-2) have less affinity but are strong enough to remove weak acids for most applications. SBA-2 resin has considerably greater regeneration efficiency thus higher capacity.

SBA-2 lacks the chemical stability of SBA-1 resins and cannot withstand high temperatures. It will significantly reduce its capacity.

SBA-2 resins are commonly used for dealkalization purposes.

Using salt alone is often satisfactory but in combination with caustic soda there is a greater reduction in alkalinity leakage and carbon dioxide. (When using the brine/caustic combination it is necessary to pre-soften to avoid precipitation of calcium and magnesium compounds.)


Weak Base Anion

Weak base anions are used for reduction of organic acids and other organic materials. There are 2 types, gel and macroporous.

Weak base resins do not contain exchangeable ionic sites and function as acid adsorbers. This is why the active form is referred to as the free base form. These resins are capable of sorbing strong acids with a high capacity and are readily regenerated with caustic. They are therefore particularly effective when used in combination with a strong base anion by providing an overall high operating capacity and regeneration efficiency.” Dupont Ion Exchange Resins- Chemical Structure Anion Exchange Resins

Anion resin in the Cl- will exchange chloride for the following:


Sulfates (SO4- -)

Nitrates (NO3- -)

Alkalinity (H2CO3)

Carbonates (CO3- -)

In the OH form anion resin will exchange hydroxide for the following:


Chloride (Cl-)

Sulfates (SO4- -)

Nitrates (NO3- -)

Alkalinity (H2CO3)

Silica (SiO2-)

Carbon Dioxide (CO2)
