  • Selenium removal using aluminum salt at conditioning and reaction stages to activate zero-valent iron (ZVI) in pironox process
    Patent number: 11208338
    Abstract: A system containing a reactor vessel including zero valent iron media, a source of a conditioning additive, a source of a reaction additive, and a process control subsystem is disclosed. A method for reducing a concentration of one or more contaminants in contaminated water including contacting zero valent iron media with a conditioning additive, contacting contaminated water with conditioned zero valent iron media, and introducing a reaction additive is also disclosed. The conditioning additive and reaction additive may each contain an aluminum salt.

  • Sulfate removal from aqueous waste streams with recycle
    Publication number: 20120205313
    Abstract: This invention provides for sulfate removal from a water source by a reverse osmosis (RO) or nanofiltration (NF) process where the concentrate stream is treated to precipitate and remove reject sulfate and recycle the discharged concentrate water and any backwash water used to clean a filter used to prepare feed water for the RO or NF process.
