Claims Analysis
Total Claims: 29
Claim 1
Independent Claim
127 words
An apparatus for the chemical decontamination of water containing layers of earth or water from a well, polluted with organic materials comprising the following units: (1) a water pressure line, means for withdrawing from said water pressure line a portion of the water which portion is to be treated and returned to the layers of earth or said water well, (2) supply means for a strong chemical oxidizing agent or bactericide, means for mixing said oxidizing agent or bactericide with said withdrawn water, (3) degassing means for removal of excess gas from said water-oxidizer mixture, (4) means for distributing said water-oxidizer mixture into a plurality of supply conduits, and (5) means for delivering said water-oxidizer mixture from said supply conduits to said polluted layers or water well.
Claim 2
Independent Claim
127 words
An apparatus for the chemical decontamination of water containing layers of earth or water from a well, polluted with organic materials comprising the following units: (1) a water pressure line, means for withdrawing from said water pressure line a portion of the water which portion is to be treated and returned to the layers of earth or said water well, (2) supply means for a strong chemical oxidizing agent or bactericide, means for mixing said oxidizing agent or bactericide with said withdrawn water, (3) degassing means for removal of excess gas from said water-oxidizer mixture, (4) means for distributing said water-oxidizer mixture into a plurality of supply conduits, and (5) means for delivering said water-oxidizer mixture from said supply conduits to said polluted layers or water well.
Claim 3
Dependent Claim
