A unit (4) consumes hydrogen peroxide at a predetermined concentration C1 and at a rate variable from 0 to D1. The apparatus (1) generates hydrogen peroxide at a concentration C2>C1 and at a rate variable between two values D2 and D3. The generated hydrogen peroxide is fed to a buffer (2) from which a variable flow is drawn, optionally diluted (at 3) and fed to the consumer unit (4). The system is useful for delivering hydrogen peroxide to paper pulp bleaching units.
