LEWATIT® ASB 2

Lewatit® ASB 2 is a premium grade, gel, strong base, Type 2, anion exchange resin based on a styrene / DVB polymer. Lewatit® ASB 2 has a slightly lower base strength than Lewatit® ASB 1 resulting in a slightly higher silica leakage in standard co-current application.

Lewatit® ASB 2 is typically applied for waters in which silica and carbonate content does not exceed 25% of the total anion content.Lewatit® ASB 2 is especially suited for separate bed applications, where ease of regeneration, higher operating capacity, and lower NaOH consumption are important considerations with respect to operating costs.

Lewatit® ASB 2 exhibits a high ion exchange capacity combined with excellent mechanical and osmotic strength for a long operating life. Lewatit® ASB 2 is supplied in a heterodispersed particle size distribution as spherical beads in the fully swollen moist chloride form. Lewatit® ASB 2 is prepared with a minimum amount of fines (-50 mesh particles) resulting in low pressure losses during service.
