摘要： The disclosed invention consists of a water oxidation method, comprising the treatment of micropollutants in bromide-containing water with ozone and hydrogen peroxide in an ozonation reactor (1), reaching reproducible low and homogenously distributed ozone concentration in the ozonation reactor. This avoids any residual of ozone in solution and therefore BrO 3 - formation. This goal is reached by a controlled addition of hydrogen peroxide to the water in a first step. The solution is then introduced in a multiplicity of hollow fiber membranes (20) permeable to gas, extended along the inner space (10) of the ozonation reactor (1). In parallel, ozone is added from the ozone filled inner space (10) of the ozonation reactor (1) with a controlled concentration (partial pressure?) through the hollow fiber membrane walls (200) in a homogenously distributed way without gas bubbles into the fiber compartments (201) carrying the water/hydrogen peroxide solution with an adjustable flow rate all along the entire hollow fiber membrane length (L).
