Abstract: Provided are water treatment systems where acid water from electrochemical devices are provided to waste streams of ion reduction devices. Specifically, electro-chemical cells having strong acid cation resins are operated to produce acid water that is supplied to the waste stream of an aqueous separation unit, for example an ion reduction device that includes, but it not limited to: deionization systems, continuous or batch-wise, and reverse-osmosis systems.

Abstract: A system includes multiple devices configured to emit and detect germicidal radiation. Each of the multiple devices operates in emitting mode when connected to a drive source in a forward bias configuration and operates in detecting mode when disconnected from the drive source or when connected to the drive source in a reverse bias configuration. Cycling circuitry generates a sequence of control signals that control switching circuitry to change the connections of the devices to the drive source in a cycle in which one or more of the multiple devices are switched to detecting mode and senses radiation emitted by one or more of the multiple devices simultaneously operating in emitting mode. Each device operating in detecting mode generates a signal in response to the sensed radiation. Detection circuitry detects signals of the devices operating in detecting mode and generates a detection output in response to the detected signals.

Abstract: A filter unit that includes a slide assembly and a head assembly. The slide assembly is moveably mounted to the head assembly. The head assembly is configured to receive an end portion of a filter cartridge in releasable engagement. The slide assembly is movable between a first position in which the slide assembly prevents disengagement of the filter cartridge from the head assembly, and a second position in which the filter cartridge is permitted to disengage from the head assembly. In the second position, the slide assembly maintains engagement with the head assembly until an external force is applied by engagement of the filter cartridge with the slide assembly when removing the filter cartridge from the head assembly.

Abstract: In general, techniques are described for filter media monitoring within a filtration system. The filter media monitoring techniques described herein include, for example, direct contact with the filter media, e.g., a sensor may be located inside a boundary defined by a surface of the filter media, or indirect contact with the filter media, e.g., a sensor may be located outside the boundary defined by the surface of the filter media such that the sensor does not make direct physical contact with the filter media being monitored.

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: Keyed fluid-handling devices comprise a fluid-handling device such as a filter, a bypass, or an adapter and an optical key. The optical keys are amenable to all types of filter component and can be readily retrofitted to existing designs. The optical keys may be formed from a variety of materials and combination of phases. That is, optical keys may comprise one or more solid materials, or perhaps may result from a combination of: solid materials, such as in transparent or semi-transparent polymers or glass; liquid fluids, such as water; and gaseous gaps such as an air gap. Optical keys may be light conduits or light guides. Filter manifolds comprise optical locks to ensure compatibility of the filter components.
