Its high surface area and short diffusion path offer higher operating capacity and faster kinetics. The macroporous structure makes it has good resistance to osmotic & mechanical shock and organic fouling. The weak acid functionality makes TC113DF has excellent regeneration efficiency. TC113DF in Hydrogen form is widely used in dealkalization and softening / demineralizing system to prolong the lifetime of strong acid cation resins. In Sodium form, TC113DF is also used for metals removal.
