  • Publication number: 20130087501
    Abstract: In a desalination system, water is treated, for example by reverse osmosis, to produce desalinated product water and a reject stream. Salt from the reject stream is transferred to a flow of low salinity wastewater, such as effluent from a municipal wastewater treatment plant. For example, the reject stream may be fed to the high salinity cell in an electrodialysis (ED) unit. The adjacent low salinity cell receives the low salinity wastewater. The high salinity and low salinity cells are separated by ion exchange membranes. The salty wastewater is discharged, for example to the ocean. The salt-reduced reject stream is treated to extract more product water from it, for example by recycling it to the feed water. Less feed water is needed to produce a given volume of product water. If a thermal desalination unit is combined with divalent ion selective ion exchange membranes, then scaling is reduced.

The at least one solvent is osmosed across the membrane and into the single-phase draw solution to form a diluted single-phase draw solution. At least one of CO2, CS2, and COS is removed from the diluted single-phase draw solution to form a first multiple-phase solution comprising a first liquid phase comprising the at least one solvent, and a second liquid phase comprising at least one of an amine compound, an amidine compound, and a guanidine compound. A liquid purification system is also described.

  • Publication number: 20120273429
    Abstract: The invention relates to a plant for separating grinding slurry originating from grinding machines into metal chips and grinding oil. According to the invention, a carrier bowl (3) in a frame (1) is filled with a divided volume of the grinding slurry (10). The carrier bowl (3) has a perforated plate (4) having an edge (5) as a floor and a sieve-like intermediate floor (8). By means of a lifting device (2), the carrier bowl (3) is moved to the effective region of an inductor plate (9) serving as a heater. The induction heat heats the ferromagnetic steel or iron particles present in the grinding slurry (10). Said heating effects a reduction in viscosity of the grinding oil in the grinding slurry (10), from which substantial portions flow downward through the openings (6) or (7). In certain cases, the effect can be improved by placing a steel plate on the free surface (16) of the grinding slurry layer (10).

    Abstract: Improved systems and processes for forward osmosis water purification or desalination are herein disclosed. According to one embodiment a process for purifying contaminated water is provided wherein a contaminated feed solution stream comprising water and with a first osmotic pressure is passed through a semipermeable membrane to a draw side having a draw solution stream with a second osmotic pressure on a draw side of the semipermeable membrane. The diluted draw solution stream is heated, agglomerated and cooled to produce a cooled single phase water rich stream that is purified to produce a water product stream.

  • Publication number: 20120097615
    Abstract: Disclosed are a method and apparatus for treating oil-containing particulates such as mill sludge comprising applying a treatment solution to a particulate feed stream to form a treated slurry, applying a mechanical disrupter to the treated slurry to reduce an average particulate size, applying a magnetic separator to the treated slurry to form a ferrous slurry, and applying a thermal separator to the ferrous slurry to extract a hydrocarbon portion and produce a ferrous product stream. This basic method and the associated apparatus may be modified in a number of ways including, for example, applying a sizing operation to the oil-containing particulates to remove larger particles from the particulate feed stream, condensing a volume of the hydrocarbon portion or using magnetic separators of varying strength to provide ferrous slurries of varying ferrous content.
