Abstract

A raceway in a fish hatchery was treated with hydrogen peroxide (H2O2), as1-h flow-through treatments, to simulate the New York State maximum allowable concentration (11.5 mg/L) in the receiving stream. Hydrogen peroxide concentrations were measured at various locations in the hatchery and in the receiving stream over a 96-h period. At the discharge pipe opening in the receiving stream, maximum mean H2O2 concentration was 9 mg/L at the end of the 1-h treatments and 2 mg/L 1 h later; at a point 15 m downstream (midstream) from the discharge pipe, maximum mean H2O2 concentrations were 2 mg/L: at discharge and 1 mg/L or less (method detection limit) 1 h later. In a second set of experiments, a desired 100 mg H2O2/L was achieved in 1-h flow-through treatments only when the test tank was pretreated to initially establish an H2O2 concentration of 100 mg/L before initiating the flow-through treatment. When the 1-h flow-through treatment was administered without pretreatment of the test tank, a maximum H2O2 concentration of 75 mg/L was achieved.
