  • Patent number: 10895229
    Abstract: The present disclosure relates to a fuel filter (1) for filtering diesel fuel supplied to an internal combustion engine (2). The fuel filter (1) includes a filter element (12, 19) for trapping and decomposing precipitates suspended in the diesel fuel. An solid acid catalyst like a zeolite is provided for decomposing precipitates trapped by the filter element (12, 19). Sterol glycosides (precipitates) are splitted into sterol and glycoside moieties, which are soluble in the biodiesel, thus preventing clogging of the filter by sterol glycoside agglomerates. The sterol and glycoside moieties pass to the engine where they are burnt. The present disclosure also relates to a method of filtering diesel fuel for supply to an internal combustion engine (2).

  • 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.

  • Patent number: 8715505
    Abstract: A desalination apparatus is disclosed which uses a salt sponge unit to remove a majority of salt from water. A parallel plate capacitor can be connected after the salt sponge to remove remaining salt ions. The salt sponge is a nanoporous, high surface area carbon scaffold to which crown ethers are attached. A power supply is connected to the salt sponges for applying a bias voltage to regenerate the salt sponges. A chlorine treatment unit can be connected after the parallel plate capacitor. A method of purifying sea water using the apparatus also is disclosed.

  • Publication number: 20140083945
    Abstract: Focal segmental glomerulosclerosis (FSGS) is a common cause of proteinuric kidney disease, which comprises both native and transplanted kidneys. Treatment was limited in the past due to the complicated pathogenesis of FSGS, including previously unidentified serum factors. Here, serum soluble urokinase receptor (suPAR) is reported to be elevated in FSGS patients but not in patients with other primary glomerular diseases. Higher pre-transplantation suPAR levels are associated with risk for FSGS recurrence in kidney grafts. Renal disease only develops when suPAR sufficiently activates podocyte ?3 integrin. Thus, disease pathogenesis can be stopped or slowed by ex vivo removal of suPAR from a subject's circulation. Removal may be measured by comparing the level (e.g., amount or concentration) of suPAR before and after such treatment.

  • Publication number: 20140034578
    Abstract: A filter intended to remove pollutants from water in developing countries can include two stages connected in series. The first stage can be coconut derived activated carbon embodied in a bamboo housing and used to remove heavy metals and pesticides. The second stage can also be coconut derived activated carbon mixed with citricidal, and used to remove bacteria. Contaminated water traverses from the first stage to the second via gravity flow, resulting in water that is free of heavy metals and bacteria.

    Abstract: A single, mixed-bed column of Birm® over Filox® to remove iron and manganese, thereby protecting Filox®, the oxidizing media, from fouling by iron and manganese. This helps to remove iron and manganese to low levels so that As(III) may be oxidized to As(V) more efficiently before it is treated with adsorptive media.

  • Patent number: 8591743
    Abstract: A portable system for extracting iodine from brine on-site is disclosed. The portable system includes a mobile platform containing a treatment unit for oxidizing iodine ions into elemental iodine, an adsorption unit capable of binding iodine, and may also have an electrolytic cell and/or a gas-liquid separator. The treatment unit and the adsorption unit may be located in the same or different portable operating devices. When transported to a field site containing natural gas wells, the natural gas wells provide a fluid stream containing natural gas and brine. The separators can separate the natural gas from the brine, and the brine is then run through the treatment unit and the adsorption unit to bind iodine present in the brine. The brine is then returned to the natural gas well. Upon saturation, the portable operating device is transported to a second location, where iodine is extracted from the adsorption unit.
