Porous-Type DIAION™ PA300 Series (Type I)
Porous-Type DIAION™ PA300 Series (Type I)
Porous-type ion-exchange resins of porous polymer matrix have good resistance against swelling and shrinking, though their exchange capacity is lower than gel-type ion exchange resins of the same degree of cross-linkage.
These are effective when highly purified effluents are needed, e.g. removal of silica to very low concentration.
They are suitable for treatments of wastewaters with organic compounds. PA312 and PA316 are generally used in wastewater treatments, and PA308 is used for demineralization and decolorization of sugar liquors.
