POROUS STATIC WATER SOFTENER CONTAINING HYBRID ZEOLITE-SILICATE COMPOSITION

摘要

A novel water softening material comprising a porous matrix such as carbon or paper having incorporated in the pores thereof an ion-exchanger composition comprising either a hybrid zeolite-silicate powder in which the zeolite contains occluded silicate which is not part of the zeolite framework or the ion-exchanger includes macroscopic aggregates of submicron aluminosilicate zeolite crystals. The submicron zeolite crystals of the aggregate can include occluded silicate. The water softening materials are particularly useful in static water softening including, for example, treating household water supplies.
