  • Patent number: 6841077
    Abstract: A novel filtration media employing polymeric absorbents comprising a material selected from the group consisting of styrene, pentadiene, cyclopentadiene, butylene, ethylene, isoprene, butadiene, propylene and mixtures thereof; and a filtration enabler intimately mixed with the polymeric absorbent. Upon contact with a hydrocarbon containing liquid, the liquid partially dissolves the polymeric absorbent forming a partial filtration barrier prior to the filtration media substantially absorbing the hydrocarbons, and allowing hydrocarbon-free liquid to flow through the filtration media. In situations of a leak or spill wherein an excess of hydrocarbons are present, the filtration media forms a plug to seal and prevent further discharge of the hydrocarbons. The filtration media may be placed inside a portable container for insertion into an existing drain such that hydrocarbon containing liquid is filtered through the device allowing hydrocarbon-free liquid to flow from the device.

  • Patent number: 6485639
    Abstract: A novel filtration media employing polymeric absorbents comprising a material selected from the group consisting of styrene, pentadiene, cyclopentadiene, butylene, ethylene, isoprene, butadiene, propylene and mixtures thereof; and a filtration enabler intimately mixed with the polymeric absorbent. Preferably, the filtration enabler comprises clay, ground glass, talc, mica, recycled rubber, sand, gravel, vermiculite, recycled plastic chips, an inert, non-absorbent material, or mixtures thereof. Preferably, the polymeric absorbent may be further compounded to incorporate about 10 to 50% recycled or waste plastic scrap, scrap polyolefins, inorganic fillers, or other inexpensive, relatively inert solids. Other compounding materials may include clay, talc, mica, ground glass, silica, and mixtures thereof.
