Abstract A continuous process for removing particulate and dissolved impurities from a liquid comprising the steps of injecting a particulate filter medium into a liquid stream to form a slurry, conveying the slurry into the bottom portion of a separation vessel, accumulating the particulate filter material in the form of a porous plug, moving said plug into the upper portion of said separation vessel, pumping the liquid through the lower portions of said plug, removing the liquid from the upper portion of the separation vessel, removing the particulate filter material from the upper end of the separation vessel above the point at which the liquid is discharged and subjecting the removed filter material to a cleansing or regeneration treatment for reuse in the process.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
17 words
The process of claim 1 wherein said particulate filter material is a particulate ion exchange filter material.
Claim 2
Dependent Claim
29 words
The process of claim 1 including the step of introducing a particulate filter material together with an ion exchange filter Material into said liquid stream to form a slurry.
Claim 3
Dependent Claim
15 words
The process of claim 1 wherein said particulate filter material is an adsorbent filter material.
Claim 4
Dependent Claim
20 words
The process of claim 1 wherein said particulate filter material has a specific gravity less than that of said liquid.
Claim 5
Dependent Claim
20 words
The process of claim 5 wherein said mixture is pumped under pressure into the bottom portion of said separation vessel.
Claim 6
Dependent Claim
43 words
The process of claim 1 including the step of continuously pumping said mixture into the bottom of said separation vessel whereby said plug increases in volume to fill an upper portion of said separation vessel extending upward from a point below said perforations.
Claim 7
Dependent Claim
36 words
The process of claim 7 including the step of removing said particulate filter material from the upper end of said separation vessel at a rate whereby the dimensions of said porous plug are maintained substantially uniform.
Claim 8
Dependent Claim
31 words
The process of claim 1 including the steps of subjecting the separated impurities to further separation treatment to recover additional filter medium and reintroducing said recovered filter medium into said process.
