Abstract
A method for continuous supply of peracetate oxidant solution with activity to generate to generate reactive oxygen species includes production processing in a liquid stream starting with a feed water and sequentially adding alkali concentrate, hydrogen peroxide solution and acetyl donor and introducing a resulting peracetate oxidant solution into a product buffer tank from which the peracetate oxidant solution is dispensed for use as a reactive oxygen species-generating oxidant, In the product buffer tank peracetate oxidant solution has a pH in a range of from pH 10 to pH 12, a molar ratio of peracetate anions to peracid in a range of from 60:1 to 6000:1 and a molar ratio of peracetate anions to hydrogen peroxide of greater than 16:1.
Claims20
A method for continuous supply of superoxide-containing peracetate oxidant solution with activity to generate reactive oxygen species for oxidative treatment, the method comprising:
- production processing in a liquid stream, comprising:
- providing a feed of the liquid stream comprising an alkaline hydrogen peroxide and superoxide solution composition;
- after the providing, adding an acetyl donor to the liquid stream to react in the liquid stream to form a peracetate-superoxide oxidant solution in the liquid stream;
- introducing the liquid stream with the peracetate-superoxide oxidant solution into a product buffer tank to collect the peracetate-superoxide oxidant solution in the product buffer tank;
- and
- dispensing the peracetate-superoxide oxidant solution from the product buffer tank for use as an oxidant;
- and
- wherein as introduced into the product buffer tank the peracetate-superoxide oxidant solution has a pH in a range of from about pH 10.5 to about pH 13.
