1 - 27 . (canceled)

28 . A method for removing components from drill water, comprising: dispensing a flocculating formulation to the water; allowing the formation of floccules in the water, wherein the floccules contain a component to be removed; and separating the floccules with the component from the water, wherein active components of the flocculating formulation consist of zinc chloride and calcium chloride.

29 . The method of claim 28 , wherein the zinc chloride and calcium chloride are in solution.

30 . The method of claim 28 , wherein the formulation is a liquid, solid, or slurry.

31 . The method of claim 28 , wherein the formulation includes water.

32 . The method of claim 28 , further comprising a second step of dispensing zirconium oxychloride or zirconium acetate or both into the water, and allowing floccules to form from the second step; and separating the floccules from the water.

33 . The method of claim 28 , wherein the drill water is produced water, frac water, or flow back water.

34 . The method of claim 28 , further comprising a second step of dispensing one or more polysaccharides selected from the group consisting of guar gum, xanthan gum, alginate, carboxymethylcellulose, chitosan, a cationic guar, a starch, a cationic starch, an anionic starch, carrageenans, pectin, arabic gum, karaya gum, tragacanth gum and glucomannan.

35 . The method of claim 28 , further comprising a second step of dispensing magnesium chloride.

36 . The method of claim 28 , further comprising a second step of dispensing ferric chloride and chitosan.

37 . The method of claim 28 , further comprising a second step of dispensing magnesium chloride and glucomannan.

38 . The method of claim 28 , further comprising a second step of dispensing zirconium acetate and chitosan.

39 . The method of claim 28 , further comprising a second step of dispensing zirconium acetate and a polysaccharide.

40 . A method for removing components from drill water, comprising: dispensing a flocculating formulation to the water; allowing the formation of floccules in the water, wherein the floccules contain a component to be removed; and separating the floccules with the component from the water, wherein active components of the flocculating formulation consist of calcium chloride and zirconium acetate.

41 . The method of claim 40 , wherein the calcium chloride and zirconium acetate are in solution.

42 . The method of claim 40 , wherein the formulation is a liquid, solid, or slurry.

43 . The method of claim 40 , wherein the formulation includes water.

44 . The method of claim 40 , further comprising a second step of dispensing zirconium oxychloride or zirconium acetate or both into the water, and allowing floccules to form from the second step; and separating the floccules from the water.

45 . The method of claim 40 , wherein the drill water is produced water, frac water, or flow back water.

46 . The method of claim 40 , further comprising a second step of dispensing a one or more of a polysaccharide selected from the group consisting of guar gum, xanthan gum, alginate, carboxymethylcellulose, chitosan, a cationic guar, a starch, a cationic starch, an anionic starch, carrageenans, pectin, arabic gum, karaya gum, tragacanth gum, and glucomannan.

47 . The method of claim 40 , further comprising a second step of dispensing magnesium chloride.

48 . The method of claim 40 , further comprising a second step of dispensing ferric chloride and chitosan.

49 . The method of claim 40 , further comprising a second step of dispensing magnesium chloride and glucomannan.
