ABSTRACT:
Apparatus for decontamination of a liquid which includes an outer envelope, apparatus for directing a liquid into the outer envelope, and apparatus for directing a liquid out of the envelope. The apparatus for directing the liquid out of the envelope includes an axial section of perforate duct and apparatus for absorbing contaminants disposed around the axial section of perforate duct, the apparatus for absorbing and the axial section of perforate duct are disposed within the outer envelope. In some forms of the invention the apparatus for absorbing contaminants is a particulate material which may be disposed within a sleeve shaped member. The apparatus for absorbing may include a central perforate tube disposed in generally concentric relationship to the sleeve shaped member and the central perforate tube may be in fluid communication with the exterior of the outer envelope. In many embodiments the outer envelope is substantially fluid impervious and may be an elongated body. The sleeve shaped member may be a second tube that is perforate and the apparatus may further include a prefilter disposed around the particulate absorber material and inside of the second tube. In some forms of the invention the apparatus further includes a fabric material, the particulate absorber material is disposed within the fabric material, and the fabric material has angular sectors defined therein to constrain movement of the particulate material. The angular sectors may be defined within an outer cylinder and an inner piece of fabric material may extend sequentially radially inwardly, a first arc, radially outwardly, radially inwardly, a second arc, and radially outwardly.
