Abstract: A dynamic filtration system and method for solid-fluid separation to eliminate or substantially reduce media blinding includes: a fluid inlet through which to receive an inlet flow of fluid to be filtered; a filter membrane; a rotatable mechanical barrier, disposed within an outer shell, to contain the filter membrane and through which to receive and filter the inlet flow of the fluid, the rotatable mechanical barrier configured to rotate dynamically along an axis, to create a high shear flow, thereby to prevent an accumulation of solids on the filter membrane, and whereby a resultant centrifugal force propels any solids and slurry onto the outer shell to be continuously removed from the dynamic filter system; a fluid outlet through which to disperse a filtered fluid; and a solids and slurry outlet through which to disperse solids and slurry collected in filtration when propelled to the outer shell of the mechanical barrier.

Abstract: Water treatment systems and methods are provided to minimize membrane fouling and the required maintenance that results therefrom. A water treatment system includes a pressure vessel with a plurality of spaced-apart membranes disposed therein, and an impeller or other means for circulating feed water through the interior of the vessel and past the membranes. Antifouling particles (such as diatomaceous earth or activated carbon) and/or pellets can be added to the feed water inhibit membrane fouling and extend the useful life of the membranes.

Abstract: A membrane filtration apparatus includes a frame, in which a plurality of membrane members, an aeration device, a cleaning device, and a jet device are provided. The cleaning device includes a rail mounted on the frame; an up frame engaging the rail to be moved in the rail, a plurality of cleaning wires respectively having an end connected to the up frame and respectively passing through a space between each two of the neighboring membrane members; and a low frame connected to opposite ends of the cleaning wires. A motor is provided to move the up frame so that the cleaning wires are reciprocating in the space to scratch the sludge off the membrane members.

Abstract: Integrated membrane treatment systems for treatment of an aqueous solution. In embodiments, components, such as an MBR, are integrated with means to recover energy from the system, for example from an RO concentrate, to operate the other components. In embodiments including biological treatment, RO is integrated with other components, such as an MBR with the ROs ability to remove inorganic nitrogen enabling biological treatment to be performed with only partial nitrification and the MBR operated without active pH control. In embodiments, RO is integrated with a chlorine generator to convert chlorides present in the RO concentrate for an in-situ source of oxidizing biocides for disinfection purposes. Chloramines may be generated in-situ from residual ammonia and chlorides in the RO reject. In embodiments, carrier media is employed in a membrane tank to enhance removal of residual organics by the MBR and to also improve effectiveness of membrane scouring.
