  • Patent number: 8753519
    Abstract: A process for removing silicon compounds from aqueous NaCl brine includes, first, adjusting a weak brine to a pH value of less than 3 with hydrochloric acid. Iron(III) chloride or other trivalent iron ions are added to the acidified weak brine, the obtained weak brine is then continuously fed to a stirred dissolution vessel which contains undissolved salt in addition to brine. Fresh salt is charged batch-wise and intermittently to the dissolution vessel to produce strong brine. The obtained strong brine is fed to a stirred buffer vessel, the pH value in this buffer vessel being maintained at a level ranging from 5 to 8. A strong-brine flow is continuously withdrawn from the buffer vessel and filtered, and the filtrate containing the added iron and silicon is discharged. Also a system for carrying out this process is disclosed.

  • Publication number: 20140163248
    Abstract: We have now discovered a novel process for the removal or extraction of metal species from a variety of solid, liquid or gas phase materials. Metal species may be removed by contacting the material suspected of containing one or more metals with a thiolated fatty acid or ester thereof for a period of time and under conditions effective for the sequestration of the metal species by the thiolated fatty acid or ester thereof. The thiolated fatty acid or ester thereof comprising sequestered metal species may then be separated and recovered from the treated material. Moreover, following the treatment of aqueous liquids or mixtures, or suspensions or dispersions of solids in aqueous liquids, the resultant thiolated fatty acid or ester thereof comprising the sequestered metal species is insoluble in water and forms a separate layer from the aqueous liquid phase, which layer may be readily removed.

The liquid is passed into an electrocoagulation system in fluid communication with a solids removal clarifier, pressurized ultrafiltration system, the draw side of forward osmosis, and a dilute draw water reverse osmosis system. Impaired water with high sulfate content is used as a source of deionized water for dilution of the forward osmosis draw solution. After concentration, the forward osmosis feed solution is further treated by lime soda softening and sludge from the softening system may be recycled to increase hardness precipitation and silica removal, the outfall from which may be treated by a separate ultrafiltration system and a feed water reverse osmosis system.

  • Patent number: 8734751
    Abstract: A method is provided for recycling and treating the wastes of silicon wafer cutting and polishing processes. To begin with, a dewatered filter cake is mixed with water so that the filter cake is diluted to form a working fluid. The water reacts with silicon in the filter cake to produce silicon dioxide and hydrogen. After the hydrogen is extracted for storage, specific gravity separation takes place via water so that silicon carbide and silicon particles are separated for sorting. Then, solid-liquid separation is performed on the remaining working fluid to separate silicon dioxide (solid) from water and PEG (liquid), before PEG is separated from water. Thus, the useful silicon particles, silicon carbide, silicon dioxide, and PEG are recycled from the filter cake to reduce the total amount of wastes. Moreover, as the side product, hydrogen, is of high commercial value, the method also adds value to recycling.

  • Publication number: 20140110339
    Abstract: A process for treatment of water. Hardness and non-hydroxide alkalinity are removed from feedwaters in amounts to substantially avoid scaling when concentrated. Sparingly ionizable components in the feedwater are urged toward increased ionization by increasing the pH of the feedwater, and, in an embodiment, up to about pH 10.5, or higher. In this manner, species such as silica become highly ionized, and (a) their rejection by membranes used in the process is significantly increased, and (b) their solubility in the reject stream from the membrane process is significantly increased. Sparingly ionized species such as boron, silica, and TOC are highly rejected, and thus, their passage through the membrane is reduced by a factor of ten or more. Recovery ratios of ninety percent (90%) or higher are achievable with many feedwaters, while simultaneously achieving a substantial reduction in cleaning frequency of membranes used in the process.

    Abstract: The invention provides waste water treatment processes utilizing an ion exchange resin to remove sulphate anions, while adjusting the pH of the ion exchange loading solution with carbon dioxide gas. The effect of the resin loading reactions is that dissolved sulphate is replaced with sequestered carbon dioxide gas, in the form of dissolved bicarbonate, in the treated water and the cations are not removed from the solution.

  • Patent number: 8641905
    Abstract: A process for treatment of water. Hardness and non-hydroxide alkalinity are removed from feedwaters to an extent sufficient to avoid scaling when concentrated. Sparingly ionizable components in the feedwater are urged toward increased ionization by increasing the pH of the feedwater. In this manner, species such as silica become highly ionized, and (a) their rejection by membranes used in the process is significantly increased, and (b) their solubility in the reject stream from the membrane process is significantly increased. Sparingly ionized species such as boron, silica, and TOC are highly rejected. Recovery ratios of ninety percent (90%) or higher are achievable with many feedwaters, while simultaneously achieving a substantial reduction in cleaning frequency of membranes used in the process.
