Q1: What is the primary functional group and ionic form of LEWATIT MonoPlus TP 207?
A: LEWATIT MonoPlus TP 207 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 potable water treatment applications?
A: Yes — LEWATIT MonoPlus TP 207 is designed for use in drinking water systems and complies with common regulatory frameworks for ion exchange resins intended for indirect contact with potable water, provided it is properly rinsed and regenerated according to manufacturer guidelines prior to service.
Q3: How does TP 207 compare to conventional gel-type cation resins in terms of kinetic performance?
A: As a macroporous resin, TP 207 offers enhanced mass transfer characteristics and improved resistance to fouling compared to standard gel-type resins, especially in applications involving organic-laden or turbid feed streams. Its uniform particle size and high crosslinking also support stable hydraulic performance across variable flow rates.
Q4: What regeneration chemicals are recommended for this resin?
A: Sodium chloride (NaCl) brine is the standard regenerant for softening operation. For full regeneration to the hydrogen form, strong mineral acids such as hydrochloric acid (HCl) or sulfuric acid (H₂SO₄) may be used, depending on system design and downstream requirements.
