    摘要: A treatment process for preparing a remediated liquid from a contaminated liquid originally containing more than 5 ppm hydrogen sulfide (H2S) and substantially without formation of precipitate, includes steps of steps of adding an aqueous solution containing at least one hydroxide compound at a collective concentration of 35-55 wt % to the contaminated liquid to achieve a concentration of 125-5000 ppm of the hydroxide compounds in the contaminated liquid, adding a fulvic acid and/or a humic acid to the contaminated liquid to achieve a concentration of 0.01-10 ppm of the acid(s) in the contaminated liquid, and dispersing the aqueous solution and the at least one organic acid in the contaminated liquid and allowing the aqueous solution and the at least one organic acid to react with the contaminated liquid for a period of time until a concentration of hydrogen sulfide in the contaminated liquid is reduced to ≤5 ppm.

    摘要: A system for treating liquids and solutions for separating components thereof, the system including a treatment vessel having a treatment chamber therein, a device for generating a gas-infused liquid under elevated pressure, and a device for stabilizing the gas-infused liquid such that most of the gas infused into the liquid by the device for generating a gas-infused liquid will remain in the liquid if pressure of the liquid is reduced to atmospheric pressure, and for flowing the stabilized gas-infused liquid into the treatment chamber so as to form a liquid layer including the stabilized, gas-infused liquid in the treatment chamber. The treatment vessel includes a discharge port through which some of the stabilized, gas-infused liquid in the liquid layer may be discharged from the treatment vessel, the withdrawn liquid is infused with an additional amount of the gas, again stabilized, and again flown the liquid into the treatment chamber.

    摘要: A treatment process for remediating; contaminants in a mixture of contaminated fluids, including at least one liquid fluid and at least one gaseous fluid, includes the steps of: preparing a treatment composition containing at least 80 volume % of an aqueous solution containing at least one hydroxide compound at a collective concentration of 35-55 weight percent, and at least one organic acid selected from the group consisting of fulvic acid and humic acid at a collective concentration of 0.1-5 wt % of the treatment composition; adding a dosage of the treatment composition to a mixture of contaminated fluids including a liquid portion and a gaseous portion; and allowing the treatment composition to react with the mixture of contaminated fluids for at least 10 minutes. A pH of the treatment composition is at least 12.0
