System for the removal of organic contaminants from water, air and soil

A method of removing organic contaminants from contaminated liquid, gas, soil in fluid form, or mixtures thereof, comprising the steps of:

• (a) producing discrete non-clumping mechanically stable geometric shapes of a blend of elastomeric material with about 5-45% by weight thermoplastic polymer;
• (b) providing the shapes in a loose form or packing;
• and
• (c) bringing a fluid containing organic contaminants into contact with the shapes in loose form or packing so that the shapes absorb organic contaminants from the fluid, wherein
• step (a) is further practiced by blending about 0.1-10% by weight foaming agent with the elastomeric material and thermoplastic polymer to produce foamed shapes.

• (d) flooding contaminated soil with water, and retrieving the water;
• and wherein
• step (c) is practiced by passing the retrieved water through a column of the geometric shapes.

A method of removing organic contaminants from contaminated liquid, gas, soil, in fluid form, or mixtures thereof, comprising the steps of:

• (a) producing discrete non-clumping mechanically stable geometric shapes of a blend of elastomeric material with about 5-45% by weight thermoplastic polymer;
• (b) providing the shapes in a loose form or packing;
• and
• (c) bringing a fluid containing organic contaminants into contact with the shapes in loose form or packing so that the shapes absorb organic contaminants from the fluid, wherein
• step (a) is further practiced to produce disc-shaped geometric shapes having a maximum dimension of about 0.5 cm, and a thickness of about 0.01-6 mm.
