Abstract
Abstract Apparatus and method for the simultaneous purification of air and water, using a plurality of compartments arranged in a series extending from a first to a last compartment. Each compartment is partially filled with a biologically active material. Air and water to be purified are introduced into the first compartment into a lower portion thereof. Each said compartment other than the last compartment has outlets for air and water adjacent an upper portion thereof communicating with conduits for conveying air and water to a lower portion of the next compartment in the series. Each compartment other than the last has a closed top such that air can leave only through the conduits and pass to a lower portion of the next compartment. The last compartment has outlets adjacent an upper portion thereof for purified air and water.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
156 words
Apparatus for the simultaneous purification of air and water, comprising a plurality of compartments, said compartments being arranged in a series extending from a first to a last of said plurality of compartments, each compartment being partially filled with a biologically active material, said first compartment having inlet means into a lower portion thereof for impure air and water, each said compartment other than said last compartment having outlet means adjacent an upper portion thereof communicating with conduit means for conveying air to a lower portion of the next said compartment in said series and outlet means for conveying water to said next compartment, each said compartment other than said last compartment having an enclosed upper portion constructed and arranged such that air can leave only through said conduit means and pass to a lower portion of said next compartment, said last compartment having outlet means adjacent an upper portion thereof for purified air and water.
Claim 2
Dependent Claim
156 words
Apparatus for the simultaneous purification of air and water, comprising a plurality of compartments, said compartments being arranged in a series extending from a first to a last of said plurality of compartments, each compartment being partially filled with a biologically active material, said first compartment having inlet means into a lower portion thereof for impure air and water, each said compartment other than said last compartment having outlet means adjacent an upper portion thereof communicating with conduit means for conveying air to a lower portion of the next said compartment in said series and outlet means for conveying water to said next compartment, each said compartment other than said last compartment having an enclosed upper portion constructed and arranged such that air can leave only through said conduit means and pass to a lower portion of said next compartment, said last compartment having outlet means adjacent an upper portion thereof for purified air and water.
Claim 3
Dependent Claim
75 words
Apparatus as claimed in claim 1, said outlet means for water being disposed at progressively lower levels in each said compartment of said series in a direction from said first to said last compartment, thereby to establish in each said compartment a water level which is lower from compartment to compartment from said first to said last compartment, said outlet means for said purified water being lower than any other said outlet means for water.
Claim 4
Dependent Claim
48 words
Apparatus as claimed in claim 1, in which said outlet means for conveying water communicates with conduit means for conveying water from adjacent an upper portion of one compartment to a lower portion of the next said compartment in a direction from said first toward said last compartment.
Claim 5
Dependent Claim
22 words
Apparatus as claimed in claim 1, wherein said outlet means for conveying air serves also as said outlet means for conveying water.
Claim 6
Dependent Claim
139 words
Method for the simultaneous purification of air and water in a plurality of compartments arranged in a series extending from a first to a last of said plurality of compartments, each compartment being partially filled with a biologically active material, comprising introducing impure air and water into a lower portion of said first compartment, removing air and water from an upper portion of each said compartment other than said last compartment, conveying the removed air to a lower portion of the next said compartment in said series, maintaining each said compartment other than said last compartment enclosed in its upper portion such that air can leave only by passing into a lower portion of the next said compartment, conveying said water from compartment to compartment, and removing from an upper portion of said last compartment purified air and water.
Claim 7
Dependent Claim
139 words
Method for the simultaneous purification of air and water in a plurality of compartments arranged in a series extending from a first to a last of said plurality of compartments, each compartment being partially filled with a biologically active material, comprising introducing impure air and water into a lower portion of said first compartment, removing air and water from an upper portion of each said compartment other than said last compartment, conveying the removed air to a lower portion of the next said compartment in said series, maintaining each said compartment other than said last compartment enclosed in its upper portion such that air can leave only by passing into a lower portion of the next said compartment, conveying said water from compartment to compartment, and removing from an upper portion of said last compartment purified air and water.
Claim 8
Dependent Claim
29 words
Method as claimed in claim 5, and establishing in each said compartment a water level which is lower from compartment to compartment from said first to said last compartment.
Claim 9
Dependent Claim
37 words
Method as claimed in claim 5, and conveying said water from adjacent an upper portion of one compartment to a lower portion of the next said compartment in a direction from said first toward said last compartment.
