Abstract: Roadways are deiced or ice formation on roadways is prevented by applying salt compositions derived from waste water streams from water softening operations.

Abstract: The methods of the present invention include processing waste water containing 0.15% by weight of the salts of Na, K, Ca, Mg, Fe, Cl, SO4, and CO3 and mixtures thereof to produce products useful for enhancing oil or gas well production, and particularly for oil drilling applications including as additives for drilling muds and cement well casings, as well as for injection into an oil well oil or gas well formation.

Abstract: The invention relates to purifying unwanted moderately saline water. The methods of the present invention including passing moderately saline water through an ion exchange media saturated with ammonium salts to produce fertilizer water. In addition, the present invention relates to a method of passing moderately saline water through a dual bed cation and anion exchange process for producing purified water. The first cation exchange media is saturated with acids of hydrochloric, nitric or sulfuric acids. Meanwhile, the second ion exchange media is saturated with ammonium hydroxide. Passing the moderately saline water through the first ion exchange media creates an acid rich water which is then passed through the second ion exchange media to remove chloride, sulfate, nitrate, and nitrite anions. Through a regenerative cycle, a fertilizer water is produced which is rich in ammonium chloride, ammonium nitrate or ammonium sulfate.

Abstract: The invention relates to a process for treating unwanted moderately saline waters for producing waters acceptable for treating soil, such as for irrigation. The treated water is also suitable for human and livestock consumption. The process includes passing moderately saline waters having 0.05% or more by weight and less than 1.00% by weight of the salts of Na, K, Ca, Mg, Fe, Cl, SO4, or CO3 or combinations thereof through an ion exchange resin. The ion exchange resin is pre-treated to be saturated with multivalent cations. Preferred multivalent cations include calcium (Ca2+) or magnesium (Mg2+) ions, or combinations thereof. After passing through the ion exchange resin, the effluent has decreased sodium cations and increased calcium and/or magnesium cations compared to the pre-treated moderately saline water.
