Lewatit® ASB 1 P is a premium grade, gel, strong base type I anion exchange resin specially suited for high purity separate or mixed bed applications if a reduction of the silica concentration is needed. The relatively open matrix of the polymer enables the user to more adequately treat waters of a higher content of organic molecules such as tannic and fulvic acids.

Lewatit® ASB 1 P is produced on the basis of a cross-linked styrene divinylbenzene polymer. It is supplied  in the form of spherical beads.

Lewatit® ASB 1 P has high an exchange capacity combined with an excellent stability to organic fouling. It contains a minimum amount of fines (up to 50 mesh), resulting in low pressure losses.
