摘要： Methods and systems for use of switchable water, which is capable of reversibly switching between an initial ionic strength and an increased ionic strength, is described. The disclosed methods and systems can be used, for example, in distillation-free removal of water from solvents, solutes, or solutions, desalination, clay settling, viscosity switching, etc. Switching from lower to higher ionic strength is readily achieved using low energy methods such as bubbling with C02, CS2 or COS or treatment with Bronsted acids. Switching from higher to lower ionic strength is readily achieved using low energy methods such as bubbling with air, inert gas, heating, agitating, introducing a vacuum or partial vacuum, or any combination or thereof.

摘要： Accelerated dechlorination of soil and water contaminated with chlorinated solvents in situ is achieved by delivering ferric ammonium citrate into the soils and/or water. The induction of ferric ammonium citrate into sulfate-rich reducing conditions initiates a combined abiotic and biotic mechanism for the dechlorination of subsurface contaminants. Initial and rapid removal of chlorinated solvents is achieved by way of reductive transformation, a mechanism utilizing the creation of an iron-bound soil mineral (pyrite) followed by stimulating conditions for enhanced biological natural attenuation.

摘要： The present invention provides a low energy alternative to conventional thermal/evaporation processes for “zero liquid discharge” treatment of strong saline brines. The products of the process include a salt-free liquid and solid salt. In particular, an antisolvent can be mixed with liquids containing high total dissolved solids. The mixture can be chilled, whereby solid salt is precipitated and separated from the mixture at near ambient temperature leaving a mixed liquor. The antisolvent can be selected from a class of organic compounds that form solutions with salt brines that exhibit a critical solution temperature lower than a critical solution temperature of the salt brines alone. The mixed liquor can be heated to a temperature above its lower critical solution temperature to produce an antisolvent liquid phase for recycle to the process. Finally, a reduced salinity aqueous phase can be polished by reverse osmosis or other conventional technology to produce clean water for discharge or beneficial use.

摘要： A method has been discovered for removing organics, such as water soluble organics (WSO), from fluids containing water, such as oil process water, by contacting the fluid with an effective amount of an organic ammonium salt. No added acid is necessary, although in some embodiments, weak acids such as glycolic acid, can be used to give synergistic improvement in organic removal. Suitable organic ammonium salts have the formula:R.sup.1 R.sup.2 R.sup.3 N.sup.+ H X.sup.-where R.sup.1 is a saturated or unsaturated alkyl group or an aryl group, or saturated or unsaturated alkyl group or an aryl group substituted with a heteroatom selected from the group consisting of N, O, S, P and halogen; R.sup.2, and R.sup.3 are independently H or a saturated or unsaturated alkyl group or an aryl group, or saturated or unsaturated alkyl group or an aryl group substituted with a heteroatom selected from the group consisting of N, O, S, P and halogen; and X is a halogen atom or an anion of a protic acid.

摘要： An ionically gellable material is gelled with a metal cation and the metal cation content of the gel is reduced to provide the gel with binding sites not occupied by the metal cation so the gel can be used to bind and remove metal cations from solution. In a preferred embodiment, a calcium alginate gel in the form of beads is prepared, the calcium ion content of the gel is reduced to between 0.01 mg/g and 1.5 mg/g of moist gel by contacting the gel with an aqueous solution of acid such as lactic or tartaric acid having a pH of 1 to 3.5. The gel can be produced containing a microorganism such as yeast used for fermentation so metal ions can be removed while fermenting with the microorganism. In the bottle fermentation of wine to produce champagne, the gel containing yeast is added to the wine in the bottle. During fermentation, calcium and potassium ions are bound by the gel to reduce the precipitation of calcium tartrate and/or potassium bitartrate. Other uses of the gel include binding metal ions which can be other than calcium ions to provide metal ions for regulating enzymic activity or for recognizing, binding or purifying organic materials such as proteins or amino acids.
