SYSTEM AND METHOD FOR GENERATION OF REACTIVE OXYGEN SPECIES AND APPLICATIONS THEREOF
A reactive oxygen species formulation is provided by preparing a peracid mixture in an activated pH range including mixing alkaline hydrogen peroxide solution with acyl donor in molar proportions with an excess of the acyl donor to hydrogen peroxide. The hydrogen peroxide and acyl donor are reacted to produce a peracid mixture comprising no more than a small quantity of hydrogen peroxide, and pH is adjusted as needed to initially prepare the formulation in the activated pH range. Water treatment with the reactive oxygen species formulation facilitates formation and separation of solids removable during clarification, and which may be followed by a second treatment with the reactive oxygen species formulation for antimicrobial treatment of clarified water.

Systems and methods of reducing a bacteria population in high hydrogen sulfide water
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.
