Granules comprise binder-agglomerated 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 comprises 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 use, 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.
