Abstract
A fully contained water treatment plant for removal of PFAS chemicals. The portable plant will allow engineers to select or modify 11 steps or stages of treatment to suit their particular water source needs. The water treatment plant combines multiple treatment methods into one synergistic process including: Advanced Oxidation (Ozone and UV), Media filtration, and reverse osmosis membrane technologies. The synergistic effect of the combined methods into one specific process will remove 99% of PFAS/PFOS chemicals and can be used to receive contaminated water from oceans, lakes, rivers, or aquifers.
Claims8
A mobile water treatment plant for use in the removal of PFAS (perfluoroalkyl and polyfluoroalkyl substances) chemicals comprising:
- an influent treatment tank for receipt of feed water;
- an ozone generator fluidly coupled to a nano bubble diffuser to provide a strong oxidant capable of destroying microorganisms with hydrophobic nano bubbles less than 100 nm in diameter;
- a 50 μm disc filter positioned after said nano bubble diffuser for removal of suspended solids;
- a first ultraviolet light providing a synergistic effect by acting on the ozone nano bubbles to create hydroxyl radicals;
- a multi-media filter constructed and arranged to remove suspended solids, sediments and granular impurities;
- a granular activated carbon filter to remove volatile organic compounds and a portion of PFAS/PFOS (perfluorooctanesulfonic acid) chemicals and remove ozone and ozone derivative oxidants from the water;
- a reverse osmosis system to overcome the osmotic pressure of the water forming a permeate with 99% of remaining PFAS/PFOS chemicals removed;
- a second ultraviolet light injecting ozone with nano bubbles into the permeate;
- and a security filter fluidly coupled to an outlet of said second ultraviolet light;
- wherein said mobile water treatment plant is mounted on a portable vehicle using ozone and ultraviolet nano bubbles in the pretreatment and posttreatment.
