FIELD: chemistry. n SUBSTANCE: invention relates to devices and methods for reduction of content of hydrogen peroxide and peracetic acid in water flow and can be used for water flow, discharged from vessel ballast tank. Device for reduction of hydrogen peroxide and peracetic acid in water flow (1) contains first measuring device (2) for determination of water flow consumption, second measuring device (3) for determination of hydrogen peroxide concentration in water flow, third measuring device (4) for determination of concentration of peracetic acid in water flow, measuring device (7) for determination of water flow salinity, dosing device (5) for dosing reducing agent into water flow as it moved after second and third measuring devices and control device (6). Control device (6) calculates quantity of reducing agent, required for reduction of content of hydrogen peroxide and peracetic acid to required value, basing on the data about water flow consumption, hydrogen peroxide concentration in water flow and peracetic acid concentration in water flow, and controls dosing device for dosing of reducing agent. n EFFECT: invention makes it possible to reliably reduce content of hydrogen peroxide and peracetic acid in water flow. n 9 cl, 1 dwg |
