Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
58 words
A method for rehabilitating or improving the permeability of a septic tank effluent seepage bed, which has become at least partly inoperative because of blocking or clogging of the soil pores in such bed, which consists of treating said bed with hydrogen peroxide in an amount sufficient to increase the permeability and thereby the functionality of said bed.
Claim 2
Independent Claim
58 words
A method for rehabilitating or improving the permeability of a septic tank effluent seepage bed, which has become at least partly inoperative because of blocking or clogging of the soil pores in such bed, which consists of treating said bed with hydrogen peroxide in an amount sufficient to increase the permeability and thereby the functionality of said bed.
Claim 3
Dependent Claim
23 words
The method of claim 1 wherein the hydrogen peroxide is used at a concentration of from about 25% to about 65% by weight.
Claim 4
Independent Claim
107 words
A method of treating the clogged or crusted and ponded effluent seepage bed of a septic system containing in combination a septic tank with an effluent exit port, and effluent distribution box or manifold, effluent distribution lines emanating from said box or manifold and an effluent seepage bed associated with said distribution lines, which method consists of, pumping said septic tank to lower the liquid level in said tank substantially below the effluent exist port, substantially reducing the volume of water ponded in said seepage bed and treating said seepage bed with hydrogen peroxide in an amount sufficient to increase the permeability thereof and thereby its functionality.
Claim 5
Independent Claim
107 words
A method of treating the clogged or crusted and ponded effluent seepage bed of a septic system containing in combination a septic tank with an effluent exit port, and effluent distribution box or manifold, effluent distribution lines emanating from said box or manifold and an effluent seepage bed associated with said distribution lines, which method consists of, pumping said septic tank to lower the liquid level in said tank substantially below the effluent exist port, substantially reducing the volume of water ponded in said seepage bed and treating said seepage bed with hydrogen peroxide in an amount sufficient to increase the permeability thereof and thereby its functionality.
