Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
184 words
In a process for determining the quality of a wastewater solution or a solution of a specific chemical which comprises mixing microorganisms with a test solution, measuring the dissolved oxygen content in the test solution, and correlating dissolved oxygen content of the mixture with a standard solution, the improvement for enhancing the sensitivity of the test while reducing the amount of time necessary to conduct a test which comprises: a. utilizing a bacterial culture in the form of a dried powder, the bacterial culture being capable of aerobic biodegradation of organic wastes; b. placing a preselected amount of said bacterial culture into a test vessel containing a preselected amount of aqueous waste which has been saturated with oxygen; c. measuring the dissolved oxygen content in the test sample as a function of time; d. determining the rate of dissolved oxygen decline at a preselected time, and, e. determining the ratio between the rate of dissolved oxygen decline at said preselected time and the rate of decline for a preselected baseline standard solution, and thereby determining the degree of inhibition of bacterial respiration or growth.
Claim 2
Dependent Claim
184 words
In a process for determining the quality of a wastewater solution or a solution of a specific chemical which comprises mixing microorganisms with a test solution, measuring the dissolved oxygen content in the test solution, and correlating dissolved oxygen content of the mixture with a standard solution, the improvement for enhancing the sensitivity of the test while reducing the amount of time necessary to conduct a test which comprises: a. utilizing a bacterial culture in the form of a dried powder, the bacterial culture being capable of aerobic biodegradation of organic wastes; b. placing a preselected amount of said bacterial culture into a test vessel containing a preselected amount of aqueous waste which has been saturated with oxygen; c. measuring the dissolved oxygen content in the test sample as a function of time; d. determining the rate of dissolved oxygen decline at a preselected time, and, e. determining the ratio between the rate of dissolved oxygen decline at said preselected time and the rate of decline for a preselected baseline standard solution, and thereby determining the degree of inhibition of bacterial respiration or growth.
Claim 3
Dependent Claim
23 words
The process of claim 1 wherein the bacterial culture contains an organism or organisms of pseudomonad, bacillus, aerobacter, azotobacter, arthrobacter, micrococcus, and nocardia.
Claim 4
Dependent Claim
37 words
The process of claim 2 wherein said dissolved oxygen content is measured at a preselected time within a range of 10 to 30 minutes or before the residual dissolved oxygen drops below 0.5 mg/l whichever is first.
Claim 5
Dependent Claim
37 words
The process of claim 3 wherein said microorganisms are combined with sufficient buffers to maintain a desired pH range during the procedure and said process is used to determine the quality of sewage containing phenol or formaldehyde.
Claim 6
Dependent Claim
24 words
The process of claim 1 wherein the quantity of preselected cultures employed is from 5 to 15 grams per 500 ml of sample solution.
Claim 7
Dependent Claim
16 words
The process of claim 5 wherein the bacterial culture employed is a mutant bacteria containing pseudomonads.
