Summary: | A device comprising a measuring device for determining the flow rate of a water stream, a measuring device for determining the concentration of hydrogen peroxide in the water stream, a measuring device for determining the concentration of peracetic acid in the water stream, a metering device for metering a reducing agent into the water stream downstream of the measuring devices for the concentrations, and a control device which, from the flow rate of the water stream, the concentration of hydrogen peroxide in the water stream and the concentration of peracetic acid in the water stream, calculates an amount of reducing agent for reducing the content of hydrogen peroxide and peracetic acid to a desired value and actuates the metering device for metering the reducing agent, makes possible reliable reduction of the content of hydrogen peroxide and peracetic acid in a water stream. The device is suitable for reducing the content of hydrogen peroxide and peracetic acid in a water stream which is withdrawn from ballast water tanks of a ship. |
