Abstract
An embodiment method includes generating a first water product and a sludge of contaminants from water to be treated using an advanced electronic-oxidation process. The advanced electronic-oxidation process includes an electronic treatment comprising a combination of electrocoagulation, electro-flocculation, electro-chlorinator, and electro-dialysis operated in synchronization with ozone. The method further includes separating the sludge of contaminants from the first water product using a filtration process, and filtering the first water product to produce a second water product and a concentrated water byproduct. The filtering includes a first sub-stage to remove particles greater than 0.02 μm to about 0.05 μm followed by a second sub-stage that includes a reverse osmosis process or a nano-filtration process. The second water is exposed product to an ultraviolet light treatment or ozonation process to generate clean water.
