    • Granules comprise binder-agglomeratd active particles for liquid treatment or filtration. Each granule has a center core of a material that itself has binding properties without the addition of other binders or sprays or adhesives, or, alternatively, each granule comprirses a matrix of active materials stuck together with the binder. The binder structure preferably ranges from a non-uniform matrix of binder formed by heat-deformed binder particles, to a clump of binder particles generally retaining the original shape or the binder particles, to non-continuous connectors of binder between active particles. The invented two-part media has high surface area per volume of media, which, because the outer surface and inner void surfaces of the particles are preferably substantially covered with active particles, translates to high activity for the preferred treatment process. Therefore, while a mixture of active particles may be used and a mixture of binders may be used, each media granule preferably consists only of a matrix, clump, or plurality of connectors of binder coated with active particles, with preferably no support for the active component other than the binder material.
    • 颗粒包含用于液体处理或过滤的粘合剂 - 凝聚的活性颗粒。 每个颗粒具有中心核心,该中心核心本身具有粘合性质,而不添加其他粘合剂或喷雾剂或粘合剂,或者,每个颗粒包封与粘合剂粘合在一起的活性材料基质。 粘合剂结构优选范围从通过热变形的粘合剂颗粒形成的粘合剂的不均匀基质到通常保持原始形状的粘合剂颗粒或粘合剂颗粒的团块到活性颗粒之间的粘合剂的非连续连接物。 本发明的两部分介质具有每单位体积介质的高表面积,由于颗粒的外表面和内部空隙表面优选基本上被活性颗粒覆盖,因此对于优选的处理过程而言具有高活性。 因此,尽管可以使用活性颗粒的混合物并且可以使用粘合剂的混合物,但是每个介质颗粒优选仅由基质,聚集块或多个涂覆有活性颗粒的粘合剂的连接器组成,优选不支撑活性颗粒 除粘结剂材料以外的其他组分。
