  • Continuous Backwash Iron Media Reactor, A Wastewater Remediation Plant, and a Method of Remediating Wastewater
    Publication number: 20230339789
    Abstract: A continuous backwash reactor including a reactive medium including iron particles suitable for use in removing from wastewater ionic species reactive with the reactive medium including iron particles, by circulating iron particles in the continuous backwash reactor while passing said wastewater through said continuous backwash reactor and recovering a reject enriched in said ionic species therefrom. Further, a PORT wastewater remediation plant and a method of remediating wastewater.

  • METHOD AND APPARATUS FOR REMOVING IMPURITIES IN REJECTS FROM SEQUENTIAL FILTERS USING SEPARATE TREATMENT UNITS
    Publication number: 20080302724
    Abstract: The disclosed method and apparatus involves the use of sequential filters for the purification of liquid. The sequential filters may each produce rejects that can be processed separately in their respective treatment apparatus, which can be fine-tuned to the specific reject that it treats. Alternatively, the first reject may be treated while the second reject may not be treated. The rejects (whether treated or not) may be combined into a combined flow and then be recycled in the sequential filters.
