  • Patent number: 9714178
    Abstract: Treatment of silica-laden wastewater is herein described. Unlike traditional fixed bed designs that cannot use an activated alumina sorbent due to the high volumes of sorbent needed in a fixed bed design, the herein disclosed continuous cycle enables smaller volumes of sorbent to be used and thereby enabling activated alumina to be used. Adsorption, regeneration, and rinse regions are provided. Activated alumina is provided to the adsorption region along with silica-containing wastewater. A pH below the zero point charge for alumina is set, and this causes the silica to load onto the alumina. Gravity brings the loaded alumina to the regeneration region, having a pH equal to or greater than the zero point charge of alumina such that the silica is released from the alumina. The silica and alumina are further separated in the rinse region, and the regenerated alumina can then be returned to the adsorption region.

  • Patent number: 9284205
    Abstract: An apparatus introduces partially-purified, softened makeup water into an open recirculating cooling system by injecting proportionated softened makeup water into a secondary side system (such as for filtering the system water) and connected to its primary recirculating system. Proportional unsoftened makeup water is introduced through the secondary side system lines. In particular, the present apparatus and method includes controlling proportional additions (via batch or continuously) of softened and unsoftened makeup water based on cycles of concentration of the system water, and based on characteristics (e.g. conductivity) of the unsoftened makeup water. For example, the present innovation allows the water softener equipment to be placed inside the building where components are easier to install, service, and maintain, while still resulting in optimal control for purposes of minimizing total makeup water required.

  • Publication number: 20150068291
    Abstract: The micro-solid phase extraction of haloacetic acids is a procedure that extracts haloacetic acids from aqueous solution using iron-modified rice husk silica as the stationary phase or sorbent. Rice husks provide an excellent source of silica. The sorbent is prepared by incinerating the husks to produce a powder that is treated with 1.0 M nitric acid for 24 hours to produce rice husk silica. The silica is washed with base, cetyltrimethylammonium bromide is added, and then titrated with a 10% Fe3+ solution to pH 5, which forms a gel. The gel is aged, filtered, dried, and calcined to produce a nitrate-free iron-modified rice husk sorbent. The sorbent is then packaged in porous, heat-sealed polypropylene membrane envelopes and used for extraction of HAAs from water. The HAA analytes are desorbed by ultrasonication in methanol for analysis and quantification.

An aqueous sample with organohalides or halide ions is contacted with the biomass material to provide a low halide filtrate and a spent biomass.

  • Patent number: 8912001
    Abstract: Provided is a method for high concentration cation exchange metathesis of divalent ions such as calcium with univalent ions such as sodium or potassium. Due to the difference between ionic valences between the exchanged ions, the provided process behavior is strongly dependent upon the selection of resin properties and to total solution normality. A combination of resin properties and solution normality is provided to achieve the cation exchange.

  • Patent number: 8859645
    Abstract: The invention pertain to a process for purifying a fluoropolymer dispersion, said process comprising: (i) providing an aqueous dispersion (D) of at least one fluoropolymer [polymer (F)]comprising at least one fluorinated surfactant [surfactant (FS)], having a solids content (SC) of 15% by weight or more; (ii) adding to said aqueous dispersion (D) at least one non-ionic non-fluorinated surfactant [surfactant (NS)]; (iii) adjusting said solid content (SC) to less than 10% by weight, to obtain a diluted aqueous dispersion (dD); (iv) contacting said diluted aqueous dispersion (dD) with at least one adsorbing material, so as to obtain an aqueous dispersion of polymer (F) having a content of the fluorinated surfactant (FS) of less than 1 ppm based on the total weight of solids. Still an object of the invention is an aqueous fluoropolymer dispersion comprising less than 1 ppm of fluorinated surfactant.

  • Patent number: 8840793
    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.

  • Publication number: 20140158629
    Abstract: A method uses anionic and cationic polymers added in, any order or simultaneously, to aqueous media for the removal of substances. The sequential addition of the two biopolymers, anionic xanthan, followed by cationic chitosan, causes the rapid formation of very large and cohesive fibrillar aggregates that may exhibit high solids to liquid ratios and that quickly settle out from the aqueous media. The aqueous media can be easily separated from the large fibrillar aggregates by settling under gravity or by filtration through a porous containment device, such as a synthetic or non-synthetic woven or non-woven fabric including a geotextile fabric or a solid containment device containing a solid mesh screen.

  • Publication number: 20140151296
    Abstract: Systems and methods for removing organic contaminants from water may be used, for example, to treat produced water from a steam assisted heavy oil recovery operation. The treated produced water may be re-used to create steam. Alternatively, the produced water may be a blowdown stream treated to facilitate further treatment in a thermal crystallizer. The treatments may include pH adjustment or separating de-solubilized organics or both. Other treatments may include one or more of oxidation, sorption and biological treatments. The treatments may be used alone or in various combinations. One exemplary combination includes reducing the pH of produced water, separating de-solubilized organics from the produced water, and oxidizing the produced water or contacting the produced water with activated carbon.
