Abstract: Aspects of the present disclosure are directed toward methods, apparatuses and systems for operating at a fluid-maintenance site. In certain embodiments, the methods, apparatuses, and systems include a fluid filter, a sensor that provides parameters that characterize fluid flowing through the fluid filter, and a wireless interface circuit. The wireless interface circuit operates in a set-up mode and a normal-operation mode. In the set-up mode, the wireless interface circuit operates by communicating authentication data with a mobile data-processing device while the mobile data-processing device is proximate to the fluid-maintenance site. In the normal-operation mode, the wireless interface circuit operates by sending the parameters wirelessly, according to the authentication protocol, to a remotely-situated server via a wireless communication medium and a broadband connection.

Abstract: Provided are media cartridges that have adjustable bypasses using linear movement, and systems and methods that use them. Aspects include an adjustable bypass filter cartridge where a treated stream and an adjusted non-treated stream combine prior to post-filtration and the percentage or ratio of treated the and the non-treated water is adjustable at the time of installation from the outside of the filter cartridge with a known or predictable level of bypass. Media cartridges comprise: an inlet in fluid communication with a feed chamber and an outlet in fluid communication with a mixing compartment; a media compartment containing a media; a bypass port in fluid communication with the feed chamber and the mixing compartment; and a bypass regulator that is adjustable by linear movement. Such cartridges maybe adjusted to meet the needs of a wide variety of end uses.

Abstract: A fluid treatment system is disclosed comprising a cross flow filter (110) comprising a feed portion, a concentrate portion, and a permeate portion. The treatment system further comprises a permeate storage apparatus (130) fluidly connected to the permeate portion and comprising a pressure boundary comprising an inner wall surrounding a pliable bladder (150), the pliable bladder fluidly separating a permeate chamber from an atmospheric chamber (170). The treatment system may further comprise a permeate pressurizing device (180) fluidly connecting the permeate chamber to a system output.

Abstract: Provided are an anti-microbial matrix and filtration systems containing the same. The matrix comprises a surface-modified inorganic component and a polymeric binder comprising particles having an irregular, convoluted surface. The surface-modified inorganic component comprises a reaction product of an anti-microbial component and an inorganic component. The anti-microbial component comprises a quaternary ammonium salt containing an epoxide group. A covalent bond is, for example, between the quaternary ammonium cation and a hydroxyl group of the inorganic component. The quaternary ammonium salt can be poly(methyldiallylamine epichlorohydrin). Further, the quaternary ammonium salt can have the formula according to I: (Formula I), wherein n is in the range of 5 to 24. The inorganic component can be diatomaceous earth. The polymeric binder can comprise ultra high molecular weight polyethylene (UHMW PE). Methods of making and using the same are also provided.

Abstract: An accumulator with a bladder or a diaphragm separating a gas chamber from an incompressible liquid chamber, the accumulator having a pressure relief valve to release gas from the gas chamber in case of overpressure; a device for filling and releasing the gas from the gas chamber.

Abstract: The present disclosure relates to a new multi component counter top water filtration system having two filtration media cartridges, one media cartridge being replaceable at least twice before the second media cartridge exceeds its useful life and requires replacement and includes a mechanism for disengaging the o-rings associated with the operative connection of the inner filter media cartridge with the outer filter media cartridge without rotation thereof during replacement of the inner filter media cartridge and includes the separation of the plumbing and electronic components wherein the lower housing unit houses the plumbing components such as the water filtration pressure vessel, tubing and flow indication signaling device and the upper unit houses the electronics component and filtration methods related thereto and methods of operating same.
