Contaminants can be removed from liquids in accordance with systems and methods herein. One exemplary method can involve introducing an input liquid into a pressurized chamber. The method can also involve oxidizing an organic or inorganic contaminant in the input liquid by heating the input liquid in the pressurized chamber, to create an output liquid that has less of the organic or inorganic contaminant than is present in the input liquid. And the method can involve outputting the output liquid from the pressurized chamber.

Provided are a system for monitoring a hydroxyl radical scavenging index in water using a real-time multi-fluorescence analyzer and a parallel factor analysis apparatus and a method therefor, wherein the system monitors the hydroxyl radical scavenging index in water using the real-time multi-fluorescence analyzer and the parallel factor analysis apparatus, whereby it is possible to monitor the characteristics of an organic material in target water through a continuous flow analysis method without using an existing indicator material, rhodamine B. In addition, in a water treatment system having an advanced oxidation process (AOP) applied thereto in which ozone, ultraviolet rays, hydrogen peroxide, and the like are combined, it is possible to simply calculate the hydroxyl radical scavenging index in the target water through an organic material characteristic index for each component obtained by classifying the characteristic structure of the organic material in water using real-time fluorescence analysis by means of a parallel factor (PARAFAC) model. Accordingly, the amount of chemical injection and the amount of ultraviolet irradiation, which are process control variables, can be controlled, and under given operating variable conditions, the removal rate of a target material in water is predicted, whereby the system can also be used as a diagnostic tool for process evaluation in the advanced oxidation process. Furthermore, the system can provide operational convenience that enables process control while reducing the amount of power consumed in the advanced oxidation process even though the type of target material and the water quality characteristics of raw water change.
