Process for treatment of porous subsrates

An assembly for supporting a porous media during a treatment which exposes the media to a fluid that modifies at least one property of the media via flow (F) of the fluid through the media, the assembly including:

• a perforate supporting core extending along an axis, the media being wrapped in a plurality of layers about the core to form a first roll of the media;
• first securement mechanisms at each end of the first roll exerting diametrical pressure on the ends of the first roll to prevent fluid flow axially out of the ends of the first roll, an additional amount of the media being wrapped in a plurality of layers about the first roll to form a second roll of the media;
• and
• second securement mechanisms at each end of wrapped layers of the second roll exerting diametrical pressure on the ends of the second roll to prevent fluid flow axially out of the ends of the second roll.

Equipment for modifying at least one property of a porous media, the equipment including:

• a treatment vessel within which the media is exposed to a fluid via flow (F) of the fluid through the media;
• a circulation pump for moving the fluid within a loop that includes the treatment vessel;
• and
• an assembly for supporting the media within the treatment vessel, the assembly including:
• a perforate supporting core extending along an axis, the media being wrapped in a plurality of layers about the core to form a first roll of the media;
• first securement mechanisms at each end of the first roll exerting diametrical pressure on the ends of the first roll to prevent fluid flow axially out of the ends of the first roll, an additional amount of the media being wrapped in a plurality of layers about the first roll to form a second roll of the media;
• and
• second securement mechanisms at each end of wrapped layers of the second roll exerting diametrical pressure on the ends of the second roll to prevent fluid flow axially out of the ends of the second roll.
