Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
60 words
A method for treating water disposable in an open, uncovered storage to inhibit the growth of algae and bacteria therein comprising the steps of: a. conducting the water along a predetermined path to open, uncovered storage; and b. producing a magnetic field in said predetermined path of sufficient strength to inhibit the growth of algae and bacteria in said water.
Claim 2
Independent Claim
60 words
A method for treating water disposable in an open, uncovered storage to inhibit the growth of algae and bacteria therein comprising the steps of: a. conducting the water along a predetermined path to open, uncovered storage; and b. producing a magnetic field in said predetermined path of sufficient strength to inhibit the growth of algae and bacteria in said water.
Claim 3
Dependent Claim
31 words
A method as claimed in claim 1 wherein said magnetic field is disposed across said predetermined path at right angles to the direction of flow of said water to said storage.
Claim 4
Dependent Claim
29 words
A method as claimed in claim 2 wherein said magnetic field is produced by a permanent magnet disposed in said predetermined path for the passage of said water thereover.
Claim 5
Dependent Claim
31 words
A method as claimed in claim 2 and comprising the step of circulating said water from said storage, through a filtration unit and said magnetic field, and back to said storage.
Claim 6
Dependent Claim
29 words
A method as claimed in claim 4 wherein said magnetic field is produced by a permanent magnet disposed in said predetermined path for the passage of said water thereover.
Claim 7
Dependent Claim
27 words
A method as claimed in claim 1 and comprising the step of circulating said water from said storage, through a filtration unit, and back to said storage.
