AQUATIC DYE AND COAGULANT COMBINATION PRODUCT TO IMPROVE THE LONGEVITY OF WATER QUALITY ENHANCEMENTS
A combination of aquatic dyes and trivalent cation-based coagulants that provide enhanced and prolonged in improvement in water quality when applied to surface water such as ponds, lakes, and reservoirs. In one embodiment, a coagulant-dye combination includes food-grade, water-soluble aquatic dyes and trivalent cation-based coagulants that are dissolved in a slightly acidic to acidic liquid solution. In another embodiment, a coagulant-dye combination is a homogeneous blend of water-soluble solids and may be contained in a water soluble packet or within a polymer to allow for the slow release of the ingredients.

a first amount of an aquatic dye; and
a second amount of a trivalent cation-based coagulant.
2 . The coagulant-dye combination product of claim 1 , wherein the coagulant-dye combination product has a pH below neutral.
3 . The coagulant-dye combination product of claim 2 , wherein the aquatic dye is a water-soluble salt and the trivalent cation-based coagulant is a water-soluble salt.
4 . The coagulant-dye combination product of claim 1 , wherein the coagulant-dye combination product is a solid blend of water-soluble salts.
5 . The coagulant-dye combination product of claim 1 , wherein the coagulant-dye combination product is a solid blend of water-soluble salts encapsulated within a water-soluble packet.
6 . The coagulant-dye combination product of claim 1 , wherein the coagulant-dye combination product is a solid blend of water-soluble salts contained inside a polymer that delays the release of the coagulant-dye combination product.
7 . The coagulant-dye combination product of claim 1 , wherein the aquatic dye includes at least one food-grade aquatic dye.
8 . The coagulant-dye combination product of claim 1 , wherein the aquatic dye includes at least one food-grade blue dye, at least one food-grade yellow dye, and/or at least one food-grade red dye.
9 . The coagulant-dye combination product of claim 1 , wherein the trivalent cation-based coagulant is water soluble and includes at least one aluminum salt, at least one aluminum polymer, at least one iron salt, at least one iron polymer, and/or at least one lanthanide salt.
10 . The coagulant-dye combination product of claim 9 , wherein the trivalent cation-based coagulant includes at least one aluminum salt, the at least one aluminum salt including aluminum sulfate and/or aluminum chloride.
11 . The coagulant-dye combination product of claim 9 , wherein the trivalent cation-based coagulant includes at least one aluminum polymer, the at least one aluminum polymer including polyaluminum chloride (PAC) and/or aluminum chlorohydrate (ACH).
12 . The coagulant-dye combination product of claim 9 , wherein the trivalent cation-based coagulant includes at least one iron salt, the at least one iron salt including ferric sulfate and/or ferric chloride.
13 . The coagulant-dye combination product of claim 9 , wherein the trivalent cation-based coagulant includes at least one iron polymer, the at least one iron polymer including ferric hydroxysulfate.
14 . The coagulant-dye combination product of claim 9 , wherein the trivalent cation-based coagulant includes at least one lanthanide salt, the at least one lanthanide salt including lanthanum chloride and/or cerium chloride.
15 . The coagulant-dye combination product of claim 1 , wherein the first amount of the aquatic dye is approximately 2.5% of the coagulant-dye combination product and the second amount of the trivalent cation-based coagulant is approximately 97.5% of the coagulant-dye combination product.
16 . A method of reducing turbidity in a body of water, the method comprising:
combining a first amount of at least one aquatic dye and a second amount of at least one trivalent cation-based coagulant to create a coagulant-dye combination product; and
applying the coagulant-dye combination product to a body of water.
17 . The method of claim 16 , further comprising, before applying the coagulant-dye combination product to the body of water:
mixing the coagulant-dye combination product with a third volume of water to create an aqueous coagulant-dye combination product, the third volume of water having an acidic pH; and
applying the aqueous coagulant-dye combination product to the body of water as the coagulant-dye combination product.
18 . The method of claim 16 , further comprising, before applying the coagulant-dye combination product to the body of water:
encapsulating the coagulant-dye combination product in a water-soluble packet to create an encapsulated coagulant-dye combination product; and
applying the encapsulated coagulant-dye combination product to the body of water as the coagulant-dye combination product.
19 . The method of claim 16 , further comprising, before applying the coagulant-dye combination product to the body of water:
packaging the coagulant-dye combination product within a polymer to form a slow-release coagulant-dye combination product, the polymer delaying release of the of the coagulant-dye combination product into the body of water; and
applying the slow-release coagulant-dye combination product to the body of water as the coagulant-dye combination product.
20 . The method of claim 16 , wherein the coagulant-dye combination product is applied in an amount sufficient to provide an application rate of the aquatic dye of approximately 290 μg/L and an application rate of the coagulant of approximately 5 mg/L.
