| Lewatit® ABS 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.Information provided by Lanxess. |
