Ion exchange resins are composed of insoluble polymer beads designed with a "functional group" that attracts ions of the opposite charge. Cations (positively charged compounds) are removed with cation exchange resins, while anions (negatively charged compounds) are removed with anion exchange resins. There are many functional sites that exist all over the bead, from the surface to deep inside.
Lanlang WQA certificate cation exchange resin is the most widely used in the water filter industry. They are available in many size gradings including uniform particle size.
1. STRONG ACID CATION GEL TYPE RESIN
2. STRONG ACID CATION MACROPOROUS TYPE RESIN
3. WEAK ACID CATION GEL TYPE RESIN
4. WEAK ACID CATION MACROPOROUS TYPE RESIN
GEL TYPE RESIN is most commonly used and has a homogeneous matrix structure inside the beads. This type of matrix gives so-called micropores that are formed by the polymeric networks. Water and solute species diffuse into and out from the bead through the micropores.
MACROPOROUS TYPE RESIN has rather large pores as well as micropores. The large pores (macropores) give improved diffusion of solutes inside beads.
