Choosing the right filter media is an investment. Here are the key features and specifications that make the Pure PA101 an ideal choice:Tipe: Strong Base Anion (SBA) Resin, Type IPhysical Form: Pale yellow spherical granulesStructure Polymer: Polystyrene crosslinked with DVBGugus Fungsi: TrimethylammoniumTotal Exchange Capacity: ≥ 1.2 eq/LWater Retention: 51-57%Particle Size: 0.315 - 1.25 mmPackaging: Original 25 liter sackThe advantages of this specification are its high ion exchange capacity, which means this resin is able to absorb more anions before requiring a regeneration process, as well as its mechanical resistance which makes it less prone to breaking during the operational process.
