Abstract
In some embodiments, a method may include treating water comprising sulfur based contaminants. The method may include contacting a portion of water comprising a quantity of hydrogen sulfide with a first oxidant. The method may include producing sulfur solids as a result of contacting the hydrogen sulfide in the portion of water with the first oxidant. In some embodiments, the method may include separating the sulfur solids from the water. The first oxidant may include hydrogen peroxide. In some embodiments, oxidation of contaminated fluids may be accelerated by adding an acid in combination with a second oxidant to the contaminated fluids. In some embodiments, oxidation of contaminated fluids may be accelerated by adjusting a pH of the contaminated fluids after addition of an oxidant to the contaminated fluids. In some embodiments, the pH may be adjusted to less than 7.
