Abstract
Abstract The composition and method are for waterways, usually closed cycle, in which algae and the like is to be killed without harm to higher animal life. The composition includes a violet dye to enhance ultraviolet light penetration from the prevailing light to enter the waterway. This ultraviolet light, with reduction in visible light, causes algae death. It also increases free oxygen, neutralizes some toxins, and reduces admission of infrared radiation. The composition includes an enzyme which digests the dead algae and similar material. The products of digestion are such as to leave clean water. A blue dye may optionally be used to hide the violet color of the water in the visible part of the spectrum.

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
69 words
A composition for the treatment of waterways, said composition comprising: a water-soluble violet dye to permit the substantial transmission of the ultraviolet fraction of ambient solar light and to reduce the transmission into the waterway of the fraction of solar light of longer wavelength than ultraviolet so as to kill at least some of the cryptogamia in the waterway; and an enzyme for digesting killed cryptogamia in the waterway.
Claim 2
Dependent Claim
69 words
A composition for the treatment of waterways, said composition comprising: a water-soluble violet dye to permit the substantial transmission of the ultraviolet fraction of ambient solar light and to reduce the transmission into the waterway of the fraction of solar light of longer wavelength than ultraviolet so as to kill at least some of the cryptogamia in the waterway; and an enzyme for digesting killed cryptogamia in the waterway.
Claim 3
Dependent Claim
20 words
The waterways treatment composition of claim 1 wherein the enzyme is a mixture of protein, cellulose and starch digesting enzymes.
Claim 4
Dependent Claim
24 words
The waterways treatment composition of claim 1 wherein said violet dye is selected from the triphenol methane group consisting of Acid Violet No. 49.
Claim 5
Dependent Claim
20 words
The waterways treatment composition of claim 3 wherein the enzyme is a mixture of protein, cellulose and starch digesting enzymes.
Claim 6
Dependent Claim
42 words
The waterways treatment composition of claim 4 further including a water-soluble blue dye for masking the color of the violet dye and giving a blue appearance to the waterway, said blue dye being substantially ineffective for reducing ultraviolet transmissivity into the waterway.
Claim 7
Dependent Claim
27 words
The waterways treatment composition of claim 5 wherein said blue dye is selected from the triphenol methane group consisting of Acid Blue Nos. 9, 11 and 15.
Claim 8
Dependent Claim
42 words
The waterways treatment composition of claim 1 further including a water-soluble blue dye for masking the color of the violet dye and giving a blue appearance to the waterway, said blue dye being substantially ineffective for reducing ultraviolet transmissivity into the waterway.
Claim 9
Dependent Claim
14 words
The waterways treatment composition of claim 7 wherein said blue dye is triphenol-methane dye.
Claim 10
Dependent Claim
90 words
A concentrated waterways treatment composition comprising: a violet dye and an enzyme in water solution, said violet dye being selected to substantially permit the transmission of solar ultraviolet into a waterway when said composition is properly diluted in the waterway so that the transmission of ultraviolet light into the waterway causes death of cryptogramia previously living in the waterway, said ultraviolet dye being selected to limit the transmission of solar radiation having a longer wavelength than ultraviolet, said enzyme being selected to digest at least part of the killed cryptogamia.
Claim 11
Dependent Claim
90 words
A concentrated waterways treatment composition comprising: a violet dye and an enzyme in water solution, said violet dye being selected to substantially permit the transmission of solar ultraviolet into a waterway when said composition is properly diluted in the waterway so that the transmission of ultraviolet light into the waterway causes death of cryptogramia previously living in the waterway, said ultraviolet dye being selected to limit the transmission of solar radiation having a longer wavelength than ultraviolet, said enzyme being selected to digest at least part of the killed cryptogamia.
Claim 12
Dependent Claim
20 words
The waterways treatment composition of claim 9 wherein the enzyme is a mixture of protein, cellulose and starch digesting enzymes.
Claim 13
Dependent Claim
