Method and device for treating ballast water with acrolein

摘要

A apparatus for treating ballast water with acrolein which is to be connected to a main ballast water line of a ballast water unit, comprises a reactor device to which acrolein derivate and water is to be fed for generating an aqueous acrolein solution, a branch line which is connected to the main ballast water line for branching off a partial ballast water stream, and a mixing device which is connected to the branch line and an acrolein solution supply line from the reactor device and is designed for diluting the aqueous acrolein solution from the reactor device, and a feed device for supplying the aqueous acrolein solution from the mixing unit to the main ballast water line. In the method for treating ballast water with acrolein, an acrolein derivate and hydrolysis water are mixed in a reactor device for generating an aqueous acrolein solution, a partial water stream branched of from the main ballast water stream at an branching location, is mixed with the acrolein solution supplied from the reactor device and mixed thereby, and the partial ballast water stream treated with the acrolein solution is fed back to the main ballast water stream downstream of the branching location.
