Strong Acid Cation Exchange ResinDetail your services

All the major strong acid cation exchange resins involved in industrial water treatment applications have a chemical matrix consisting of styrene and divinylbenzene.

The functional groups are sulfonic acid radicals. The resins vary mainly in divinylbenzene content or matrix structure (gel/isoporous/macroporous).

Generally, in water softening, a strong acid cation exchange resin with 6 - 8% divinylbenzene crosslinking is used. 220 Na and 225 Na are examples of this resin. For demineralisation the main resin that is used is the cation resin in hydrogen form, for example 225 H.

Weak Acid Cation Exchange Resin

In industrial water treatment applications, weak acid cation exchange resin is used primarily where there is a high degree of hardness and a high degree of alkalinity.

This resin has the capacity of exchanging all cations associated with alkalinity to a much greater degree than strong acid cation exchange resins. A weak acid cation exchange resin consists of polyacyrlic acid divinylbenzene matrix with carboxylic functionality and gel structure.

The major advantage of this resin is that it can be regenerated with stoichiometric amounts of regenerant, and is therefore, much more efficient. INDION 236 is an example of this resin.

Strong Base Anion Exchange Resin

Strong base anion exchange resins can be divided into two categories called Type I and Type II. The Type I resin has the highest overall basicity, and, therefore, gives best effluent quality. The Type II resin also removes anionic constitutents, but has as lower basicity, and therefore, requires less caustic during the regeneration cycle. In general, a Type II strong base anion exchange resin is recommended where silica effluent quality is not as critical, and also where a relatively high chloride and/ or sulphate content prevail in the raw water.

INDION FFIP is an example of strong base Type I and INDION NIP is an example of strong base Type II anion resin.

For applications where higher physical strength is required, macroporous resins are also available e.g. 810. All strong base anion exchange resins continuously undergo hydrolysis - a process that converts the strong base groups present in the resin into weak base groups.

The net result is a gradual loss of capacity to remove weak acids like carbon dioxide and silica. Type II resins undergo hydrolysis at a faster rate as compared to Type I resins. Type I resins are therefore preferred where low residuals of silica are required in treated water.

Weak Base Anion Exchange Resin

In the field of deionisation, weak base anion exchange resin is used primarily to remove strong acids such as hydrochloric and sulphuric acid. Unlike strong base anion exchange resin, weak base resin does not have the capability to remove carbon dioxide and silica; however it has a much higher capacity for the removal of chlorides and sulphates. The resin can be of gel or macroporous structure.

For treatment of water which does not present organic fouling problems, the gel type weak base resin is used. For treatment of water containing organic contaminants (humic and fulvic acids), macroporous weak base anion resins are preferred. 850 is an example of macroporous weak base anion resin.
