Abstract
A machine and process for treating contaminated water having a chamber with at least two electrodes having voltages of different polarities and made of metals containing multivalent salts; an inlet port for introduction of untreated contaminated water to the chamber, wherein the water is treated by passing over the electrodes; an outlet port for outputting the treated water from the chamber; and one or more scraper blades in close proximity with the electrodes wherein the blades are capable of movement along the length of the electrodes to remove accumulated debris. A preferred embodiment includes electrodes are made of noble elements and the scraper is affixed in close proximity to the electrode for removal of debris. Another preferred embodiment includes having the electrodes oriented along a vertical flow of the water. Another preferred embodiment includes a drum shaped electrode that rotates about a shaft while it facilitates cleaning of the electrodes. The cleaning motion is motor driven.
