Systems for reducing hydrogen peroxide in wastewater

A system (100) for removing hydrogen peroxide from wastewater, the system comprising: a first reaction tank (135) having an inlet fluidly connectable to a source of the wastewater; a source of dilution water (105) having a lower concentration of hydrogen peroxide than the wastewater in fluid communication with the inlet of the first reaction tank; a source of ferrous salt in fluid communication with the first reaction tank (140); a source of acid in fluid communication with the first reaction tank (145); a second reaction tank (150) having an inlet in fluid communication with an outlet of the first reaction tank; and a source of a base in fluid communication with the second reaction tank (155).
