Q1: What is the primary functional group and ionic form of LEWATIT MDS 1368 K 320?
A: LEWATIT MDS 1368 K 320 is a strongly acidic cation exchange resin in the potassium (K⁺) form, featuring sulfonic acid functional groups grafted onto a macroporous polystyrene-divinylbenzene matrix.
Q2: Is this resin suitable for food-grade or pharmaceutical water polishing applications?
A: Yes — LEWATIT MDS 1368 K 320 is designed for high-purity water treatment and is commonly used in final polishing stages for pharmaceutical, biotech, and food & beverage applications where low leachables and high chemical stability are required. It complies with relevant global regulatory expectations for indirect food contact and pharmaceutical water systems when validated per application-specific protocols.
Q3: How does the macroporous structure benefit performance in challenging feed waters?
A: The macroporous architecture provides enhanced resistance to fouling from organic matter, colloids, or suspended solids, and maintains consistent ion exchange kinetics even under variable pH or temperature conditions — making it particularly robust for pretreated wastewater, industrial process streams, or low-quality influents.
Q4: Can this resin be regenerated, and what are typical regeneration agents?
A: Yes — LEWATIT MDS 1368 K 320 is fully regenerable using standard strong acid solutions such as hydrochloric acid (HCl) or sulfuric acid (H₂SO₄). Regeneration efficiency and cycle life depend on operating conditions, but the resin demonstrates excellent stability across multiple regeneration cycles under recommended protocols.
