Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
73 words
The method for treating sewage treatment systems for elimination of grease, hydrogen sulfide, and sewage odors where said systems contain an adequate source of proxeroninase, comprising the step of: (a) adding a commercial source of proxeronine into various grease traps located along the sewage treatment system, the addition of proxeronine to proxeroninase being in a sufficient quantity to yield xeronine which stimulates metabolic function of aerobic and anaerobic bacteria which breaks down grease.
Claim 2
Independent Claim
73 words
The method for treating sewage treatment systems for elimination of grease, hydrogen sulfide, and sewage odors where said systems contain an adequate source of proxeroninase, comprising the step of: (a) adding a commercial source of proxeronine into various grease traps located along the sewage treatment system, the addition of proxeronine to proxeroninase being in a sufficient quantity to yield xeronine which stimulates metabolic function of aerobic and anaerobic bacteria which breaks down grease.
Claim 3
Dependent Claim
16 words
The method of claim 1 where said adding is performed by means of an automatic dispenser.
Claim 4
Dependent Claim
29 words
The method of claim 1 where said commercial source of proxeronine further comprises 5% w/w kelp extract, Morinda citrofolia fruit juice, the juice pressed from pineapple stems, pineapple cannery.
Claim 5
Dependent Claim
26 words
The method of claim 1 wherein the proxeronine is added in quantities of approximately 1.4 micrograms per gallon of waste running through the sewage treatment systems.
Claim 6
Independent Claim
75 words
A method for eliminating grease, hydrogen sulfide, and sewage odors from sewage treatment systems containing no adequate source of proxeroninase, comprising the steps of: (a) mixing a source of proxeroninase with a source of peroxeronine; and (b) adding said mixture to a sewage treatment system, the proxeroninase and the proxeronine being in a sufficient quantity to yield a sufficient quantity of xeronine to stimulate the metabolism of anaerobic and aerobic bacteria which breaks down grease.
Claim 7
Independent Claim
75 words
A method for eliminating grease, hydrogen sulfide, and sewage odors from sewage treatment systems containing no adequate source of proxeroninase, comprising the steps of: (a) mixing a source of proxeroninase with a source of peroxeronine; and (b) adding said mixture to a sewage treatment system, the proxeroninase and the proxeronine being in a sufficient quantity to yield a sufficient quantity of xeronine to stimulate the metabolism of anaerobic and aerobic bacteria which breaks down grease.
Claim 8
Dependent Claim
13 words
The method of claim 5 where said source for proxeroninase further comprises whey.
Claim 9
Dependent Claim
14 words
The method of claim 6 where said source for proxeronine further comprises kelp extract.
Claim 10
Dependent Claim
16 words
The method of claim 6 where said adding is performed by means of an automatic dispenser.
Claim 11
Dependent Claim
26 words
The method of claim 5 wherein the proxeronine is added in quantities of approximately 1.4 micrograms per gallon of waste running through the sewage treatment systems.
