    Abstract: The prefilter assembly is provided with a central cavity in which a plurality of tubular porous tubular elements are provided with the remaining space being filled by a mass of shattered metal particles. During filtration, the shattered metal particles eliminate dead space within the filter while also filtering out micro gels which may be in the polymeric material. The shattered metal particles also reduce the possibility of gel formation due to cross-linking of the polymer mass therethrough.

    Abstract: The filter assembly is constructed of outer sleeves of wire screen, a mass of shattered metal particles within the sleeves and at least one tubular filter element within the shattered metal particles. The mass of shattered metal particles serves to remove micro-gels from the polymeric material flowing through the filter assembly while the inner filter element serves to remove particulate matter.
