Fluid Purification Filters And The Method of Fluid Purification Using The Same

A method of purifying a contaminated fluid, the method comprising:

• providing a filter
• passing a contaminated fluid comprising at least one contaminant through the contaminated fluid sample inlet;
• passing a purification material through the purification material inlet;
• permeating the at least one contaminant through the tubular membrane to the housing lumen;
• and
• collecting a purified fluid;
• wherein the filter comprises:
• a tubular housing having a proximal end, a distal end and a housing lumen therethrough;
• a tubular membrane having a proximal end, a distal end and a membrane lumen therethrough, wherein the tubular membrane is positioned within the housing lumen;
• a contaminated fluid sample inlet fluidly connected to the proximal end of the membrane, and a contaminated fluid sample outlet fluidly connected to the distal end of the membrane, thereby creating a sample flow-path from the sample inlet through the membrane lumen to the sample outlet;
• and
• a purification material inlet fluidly connected to a distal region of the housing lumen, and a purification material outlet fluidly connected to a proximal region of the housing lumen, thereby creating a purification material flow-path from the purification material inlet through the housing lumen to the purification material outlet;
• wherein the direction of the sample flow-path is in the opposite direction of the purification material flow-path;
