Ion exchange resin pictures
IntroductionThis page shows pictures of resins taken under the microscope in the laboratory. You will see gel type transparent resins, macroporous opaque resins, and you will observe the difference between uniform particle size resins and traditional products with a "Gaussian distribution".
Not all photographs were taken at the same magnification, so their appearance in terms of particle size is not significant. Most ion exchange resins have a particle size between 0.3 and 1.2 mm. Click on the small pictures to see them enlarged.
Pictures of new resins
A uniform, gel type SAC resin used for water softening and demineralisation in separate and mixed bed units. Uniform resins are particularly suitable for packed bed systems.

A uniform, gel type SAC resin used for water softening and demineralisation.
A uniform, gel type SAC resin with higher cross-linking used for condensate polishing.
A uniform, gel type SBA resin used for water demineralisation in separate and mixed bed units.
A uniform, gel type 1 SBA resin with higher cross-linking used for Stratabed and high performance mixed bed units. Amberjet 4400 has a particle size of 0.58 mm in the chloride form.
A traditional, gel type SAC resin used for water softening and demineralisation with co-flow regeneration. Compare particle size distribution with Amberjet 1200 above.
A traditional, gel type 1 SBA resin used for water demineralisation with co-flow regeneration. Compare particle size distribution with Amberjet 4200 above.
A gel type WAC resin used for water de-alkalisation and demineralisation with co-flow regeneration. Other grades are available for packed and stratified beds.
A gel type, acrylic WBA resin used for water demineralisation when the organic load is high.
A macroporous styrenic WBA resin used for water demineralisation in packed beds. This is the best WBA resin in the marketplace.
You see that this resin is opaque, because it is macroporous (see resin structure).
A macroporous styrenic SBA resin used for condensate polishing. It is semi-uniform, and pairs ideally with Amberjet 1500 in this application.
A macroporous SAC resin used for condensate polishing (in its RF grade) and various special applications. It has an outstanding physical stability.
A macroporous SAC resin used in the food industry. It is super-sulphonated for high performance, and can withstand the most adverse operating conditions.
A macroporous special resin with thiol functionality for selective removal of mercury, cadmium and other heavy metals.
|A uniform macroporous resin
A macroporous resin with unusually uniform particle size. The picture is beautiful, but I don't know the exact type.
A mixture of SAC and SBA resins (both gel type) of high purity for radioactive waste treatment in the nuclear power industry. This resin has a high capacity, a big advantage for products that are not regenerated and must be stored after use as radioactive solid waste.
A mixture of SAC and SBA resins with a colour indicator of exhaustion. It is sold for household filter cartridges to produce demineralised water for steam irons and other uses.
This is a highly cross-linked non-ionic macroporous adsorbent resin used in the food industry.
An inert material used at the top of floating bed and StratapackTM units (see ion exchange columns). Its specific gravity is less than 1.0 so it floats in water. It protects the top nozzles or collector from clogging.
This curious product is a non-ionic adsorbent based on a phenol-formaldehyde matrix. Its particles are not spherical beads like most resins, but have an irregular granular shape.
|Imac HP333 under ESM
This picture was taken by an electron scanning microscope and shows the surface of a weakly acidic macroporous resin used in drinking water treatment.
|Amberlite 200 under ESM
This picture shows the structure of a strongly acidic macroporous resin with high porosity.
