  • Systems and processes for the treatment of waste streams allowing direct activated carbon and membrane contact
    Patent number: 10550009
    Abstract: Methods of treating a high suspended solids liquor having a waste stream and a suspended solids content including powdered activated carbon and biological material by contacting the high suspended solids liquor with a membrane unit are disclosed. Methods of treating a waste stream by combining the waste stream with powdered activated carbon and biological material to produce the high suspended solids liquor and contacting the high suspended solids liquor with a membrane unit are also disclosed. Treatment systems including a membrane unit fluidly connected to a source of a high suspended solids liquor are disclosed. Treatment systems including a bioreactor fluidly connected to a source of a waste stream and a membrane unit are also disclosed.

  • WATER TREATMENT ARRANGEMENT FOR STEAM-ASSISTED OIL PRODUCTION OPERATION
    Publication number: 20140251806
    Abstract: A water processing arrangement (18) for steam assisted oil production, having a water softening system (30) configured to remove silica from a stream of producer well water (64, 66) using a caustic (70), and an electrodeionization-based water deionization system (36) downstream of the water softening system configured to deionize the stream of water (66) A byproduct of the electrodeionization is caustic NaOH which is recycled to the softening system
