Abstract: A method of reducing the organic compounds in an aqueous stream by generating an oxidant in-situ using at least one electrolytic cell. The method may comprise contacting at least a portion of the aqueous stream with the electrolytic cell. The electrolytic cell may have at least two electrodes, wherein at least one electrode is a metal electrode and, a power source for powering the at least two electrodes. A water treatment system for generating an oxidant in-situ comprising at least one electrolytic cell. The electrolytic cell may have at least two electrodes, wherein at least one electrode is a metal electrode, and a power source for powering the at least two electrodes. A method of improving the rejection rate of a reverse osmosis membrane using an oxidant generated in-situ. The method may comprise contacting at least a portion of the aqueous stream with the electrolytic cell thereby creating an oxidized aqueous stream. At least a portion of the oxidized aqueous stream may be fed through a reverse osmosis membrane. The electrolytic cell may comprise at least two electrodes, wherein at least one electrode is a metal electrode, and a power source for powering the at least two electrodes.
