Abstract: An oily waste treatment array (23) is described, for use in a Marpol plant, allows the separation of low and high-flash-point material into high-flash-point dehydrated recovered oil, cleaned water, and solids, that can be operated in an urban environment. This can be achieved due to the coupling of six constituent devices, linked within the confines (28) of the sealed array (23), that enables odor control, and due to the unique treatment (30), prior to the centrifuge array (31). The pre-treatment array (30) allows the treatment of emulsified mixtures, optimizing the use of chemical additives, by use of an external-flow-array, that is thermally coupled and integrated within the overall array, that features an external circulation heating/stirring loop, in and out of an inclined and contracting tank (20), a ‘stirring region’ (41) and a series of three dimensional injection nozzles (9), making up a ‘dendrite’ structure (10).

Abstract: An oil deterioration suppressing apparatus is provided. The apparatus may include a filtering portion including a filter element for filtering oil, and a deterioration suppressing portion including a powdery deterioration retarder which suppresses deterioration of oil. The deterioration suppressing portion may include a flow passage wall which holds the powdery deterioration retarder and defines an oil flow passage, and the powdery deterioration retarder includes mesoporous inorganic material.

Abstract: A water injection process plant includes a catalytic deoxygenation unit located subsea that makes use of a reducing agent sent from topsides in liquid form. The catalyst is preferably a palladium catalyst or its equivalent. The reducing agent is an oxygen scavenger such as but not limited to hydrazine, carbohydrazide, sodium erythorbate, methyl ethyl ketoxime (“MEKO”), hydroquinone, diethylhydroxylamine (“DEHA”), formic acid (methanoic acid). A chemical umbilical can be used to deliver the reducing agent to a mixer located upstream of the deoxygenation unit, where the agent is mixed with seawater containing oxygen.

Abstract: A barrier of open pore mesh provided with a superhydrophobic coating to prevent wetting when exposed to an aqueous liquid. The disclosed barrier could be a mesh screen or a liquid pervious membrane. The barrier is useful in a filter media containment to permit egress of gas, usually air, from the containment even when subjected to an aqueous liquid containing environment.

Abstract: A method of treating primary sludge and activated sludge produced by a wastewater system is disclosed. A portion of the activated sludge is wasted to form biological sludge. The biological sludge is thermally hydrolyzed. The method entails cooling the thermally hydrolyzed biological sludge by mixing primary sludge with the thermally hydrolyzed biological sludge. Thereafter, the combined sludge is directed through a pasteurization process and then to an anaerobic digester which performs anaerobic digestion of the combined sludge.

Abstract: A filter for a non-plumbed appliance is provided. The filter includes a filter housing defining a filter chamber. A filter medium is positioned within the filter chamber, each end of the filter medium being enclosed by an endcap formed from a resilient material, such as molded silicone or a thermoplastic elastomer. The endcaps slide on the ends of the filter media with no need for adhesive and form a fluid seal with both the filter media and the filter housing once installed. One or more fluid bypass channels may be defined by the filter housing or in the endcaps to allow water to flow as desired within the filter chamber. The resulting filter requires fewer components and less assembly time while improving filtration performance and reliability.

Abstract: A cross-linked polymeric resin which contains reacted monomer units of an aniline, a diaminoalkane, and an aldehyde, and which is functionalized with at least one dithiocarbamate moiety. A process for producing the cross-linked polymeric resin whereby an aniline and a diaminoalkane are linked together by Mannich-type polycondensation reactions with an aldehyde. The resulting Mannich-type polycondensation product is converted into the cross-linked polymeric resin through functionalization of one or more amine functional groups with dithiocarbamate moieties. A method for removing heavy metals, such as Hg(II), from an aqueous solution, whereby the cross-linked polymeric resin is contacted with the aqueous solution, and the heavy metal is thus adsorbed onto the cross-linked polymeric resin.

Abstract: A water distillation system including a reservoir unit configured to reserve a second liquid of higher concentration than the first liquid; a pipe including a first end communicated with the first liquid and a second end communicated with the second liquid in the reservoir unit; a semipermeable membrane fitted on the pipe to separate the first liquid and the second liquid, so that the first liquid is mixed into the second liquid through the semipermeable membrane and led to the reservoir unit by osmotic action; and a distillation unit configured to distill the second liquid in the reservoir unit by solar energy.

Abstract: Blends comprising a sulfonated block copolymer and particulate carbon are useful materials for membranes, films and coatings in applications which require high dimensional stability, high water vapor transport, high conductivity, and low flammability. The sulfonated block copolymer comprises at least two polymer end blocks A and at least one polymer interior block B wherein each A block contains essentially no sulfonic acid or sulfonate functional groups and each B block is a polymer block containing from about 10 to about 100 mol percent sulfonic acid or sulfonate functional groups based on the number of monomer units of the B block.

Abstract: A filter device for fluids has a connection member (1) with a fluid input (19) for unfiltrate and fluid output (13) for filtrate, a first (43) and second filter elements (3) and a switching device (29) located in the connection member (1). By the switching device, a fluid connection between the fluid input (19) and fluid output (13) can be selectively established via the first filter element (43) or the second filter element (3). One of the filter elements is integrated into the interior of the connection member (1) as an auxiliary filter (43).

Abstract: A membrane separation device is provided with membrane modules comprising multiple membrane elements, a frame body accommodating the membrane modules stacked in multiple stages, a stopper for closing an end portion of the frame body to prevent the membrane modules accommodated in the frame from being released, and elastic members which, arranged in a state of elastic deformation in the vertical direction in the frame with the end portion of the frame being closed, suppress vertical vibration of the membrane modules accommodated in the frame, whereby making it possible to avoid vibration of the membrane modules inside the frame body even if the volume of the membrane modules accommodated in the frame body varies.
