Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
63 words
A composition for addition to sewage to accelerate reduction of sludge to soluble or finely dispersed state and to minimize generation of hydrogen sulfide comprising a mixture of triacontanol and the liquid product of a first digestion of milch cow excrement under mild acid condition and further digestion of liquid portions from the first digestion by the action of algae and solar radiation.
Claim 2
Dependent Claim
63 words
A composition for addition to sewage to accelerate reduction of sludge to soluble or finely dispersed state and to minimize generation of hydrogen sulfide comprising a mixture of triacontanol and the liquid product of a first digestion of milch cow excrement under mild acid condition and further digestion of liquid portions from the first digestion by the action of algae and solar radiation.
Claim 3
Dependent Claim
29 words
A composition as define in claim 1, in which said triacontanol is present in amount of at least 0.1 ppm. based on the weight of said liquid digestion product.
Claim 4
Dependent Claim
10 words
A composition as defined in claim 2, comprising B vitamins.
Claim 5
Dependent Claim
53 words
A composition as defined in claim 3 in which said triacontanol is present in amount of from about 0.1 ppm. to about 5 ppm. and said B vitamins comprise from about 0.02% to about 0.15% by weight of each of thiamine, riboflavin and niacin based on the weight of said liquid digestion product.
Claim 6
Independent Claim
71 words
A method for the treatment of sewage containing excrement to accelerate reduction of sludge to soluble or finely dispersed state and to minimize generation of hydrogen sulfide comprising mixing with said sewage a treatment agent comprising triacontanol and the liquid product of a first digestion of milch cow excrement under mild acid conditions and further digestion of liquid portions from the first digestion by the action of algae and solar radiation.
Claim 7
Independent Claim
71 words
A method for the treatment of sewage containing excrement to accelerate reduction of sludge to soluble or finely dispersed state and to minimize generation of hydrogen sulfide comprising mixing with said sewage a treatment agent comprising triacontanol and the liquid product of a first digestion of milch cow excrement under mild acid conditions and further digestion of liquid portions from the first digestion by the action of algae and solar radiation.
Claim 8
Dependent Claim
35 words
A method for the treatment of sewage as defined in claim 5, in which at least about 40 ppm. of said treating agent based on the weight of said sewage is added to said sewage.
Claim 9
Dependent Claim
20 words
A method for the treatment of sewage as defined in claim 6, in which said treating agent includes B vitamins.
Claim 10
Dependent Claim
70 words
A method for the treatment of sewage as defined in claim 7, in which said triacontanol is present in said treating agent in amount of from about 0.1 ppm. to about 5 ppm., based on the weight of said digestion product and said B vitamins comprise from about 0.02% to about 0.15% by weight of each of thiamine, riboflavin and niacin based on the weight of said liquid digestion product.
