Q1: What is the primary functional group and ionic form of LEWATIT MonoPlus TP 260?
A: LEWATIT MonoPlus TP 260 is a strongly acidic cation exchange resin based on a styrene-divinylbenzene matrix, functionalized with sulfonic acid groups. It is supplied in the sodium (Na⁺) form, making it suitable for softening and selective removal of multivalent cations such as Ca²⁺ and Mg²⁺.
Q2: Is this resin suitable for use in pharmaceutical or food-grade water treatment applications?
A: Yes — LEWATIT MonoPlus TP 260 is manufactured and tested to meet requirements for use in potable water and high-purity process water systems. It complies with relevant global regulatory frameworks for indirect food contact and pharmaceutical water purification, subject to proper regeneration and system validation per end-use specifications.
Q3: How does TP 260 differ from conventional gel-type cation resins in terms of physical structure and performance?
A: TP 260 features a uniform particle size distribution and a macroporous morphology, which enhances kinetic performance, improves resistance to fouling from organic matter or suspended solids, and provides greater stability under variable flow and temperature conditions compared to standard gel-type resins.
Q4: What are typical regeneration requirements for this resin?
A: Regeneration is typically performed using sodium chloride (NaCl) brine at concentrations between 8–12% w/w. The required regenerant dosage and contact time depend on service cycle length, influent water quality, and system design — however, TP 260 generally achieves efficient regeneration with moderate chemical consumption due to its high exchange capacity and uniform bead structure.
