Drain System

Abstract

Target organic substance can be contained, filtered, absorbed and/or used to shut down flow, and water drained off, with a system having a first, fluid-permeable, hollow housing member; a second, fluid-permeable, hollow housing member disposed inside the first member; and, disposed between the first and second members, a fluid-filtering/absorbing material. A fluid can pass through the first and second members and the fluid-filtering/absorbing material, and have the target organic substance, which may be found with the fluid, filtered and/or absorbed by the fluid-filtering/absorbing material.

1 . A system for containing, filtering, absorbing organics, draining off water and/or shutting down flow of a target organic substance, which comprises:
 a first, fluid-permeable, hollow housing member;   a second, fluid-permeable, hollow housing member disposed inside said first member; and   a fluid-filtering and/or absorbing material disposed between said first and second members,   
     such that a fluid can pass through said first and second members and the fluid-filtering/absorbing material, and have the target organic substance, which may be found with the fluid, be filtered and/or absorbed by the fluid-filtering and/or absorbing material. 
   
   
       2 . The system of  claim 1 , wherein said material includes water insoluble, particulate polymer particles which can imbibe the target organic substance. 
   
   
       3 . The system of  claim 2 , wherein said first and second members are in forms of tubes; a first nonporous cap is disposed about first ends of said tubes; and a second nonporous cap is disposed about second, opposing ends of said tubes and has an opening for communication of a throughput with respect to the hollow volume of said second member tube. 
   
   
       4 . The system of  claim 3 , wherein said first and second member tubes are made of a porous plastic. 
   
   
       5 . The system of  claim 4 , wherein said porous plastic has pores about from 90 microns to 130 microns. 
   
   
       6 . The system of  claim 5 , wherein said porous plastic is HDPE. 
   
   
       7 . The system of  claim 6 , wherein said first and second member tubes have about 0.125-inch (3.175-mm) thicknesses to their walls, and an outer protective mesh is employed about said first member tube. 
   
   
       8 . The system of  claim 2 , wherein holes or slots are provided in walls of at least one of said first and second members, and filter fabric  32  is provided to keep said material from passing through the holes or slots. 
   
   
       9 . A method for containing, filtering, absorbing organics, draining off water and/or shutting down flow of a target organic substance, which comprises:
 providing a system, which includes:
 a first, fluid-permeable, hollow housing member; 
 a second, fluid-permeable, hollow housing member disposed inside said first member; and 
 a fluid-filtering and/or absorbing material disposed between said first and second members, 
   such that a fluid can pass through said first and second members and the fluid-filtering/absorbing material, and have the target organic substance, which may be found with the fluid, be filtered and/or absorbed by the fluid-filtering and/or absorbing material; and   installing the system such that it can receive an input of a fluid that may contain the target organic substance.   
   
   
       10 . The method of  claim 9 , wherein an opening for communication of a throughput is provided such that said fluid would be communicated to the hollow volume of said second member, and flow of said fluid would pass through said material and said first member; said material includes water insoluble, particulate polymer particles which can imbibe the target organic substance; and said fluid would include water. 
   
   
       11 . The method of  claim 10 , which operates as a drain, and wherein the target organic substance includes at least one substance that is a class “1” or class “2” organic chemical or mixture. 
   
   
       12 . The method of  claim 10 , which operates as a drain, and wherein the target organic substance includes at least one of #2 diesel fuel; #1 or #2 fuel oils; kerosene; Jet A-1, JP-4, JP-5, JP-8 or JP-8-100 jet fuels; VM&P naphtha; gasoline; xylene; toluene; benzene; pentane; hexane; heptane; octane, nonane, decane; motor oil; a transformer oil; trichloroethylene, dichlorobenzene; styrene; methylmethacrylate; butyl acrylate; acrylonitrile; acrylic acid; an isocyanate; and an alcohol.
