摘要： Provided are electrochemical devices that are rechargeable, where the regeneration techniques are based on a batch-wise application of current or current density to the cells, where there are a service mode where no current or current density is applied and a recharge mode where a current or current density is applied. Electrochemical and EDI systems according to the embodiments herein are suitable for deionization and/or purification of typical municipal tap quality water in applications where demand for purified, low-TDS water is intermittent. Such operations avoid the use of chemical additions for regeneration purposes. In addition the cells provided herein are amenable to small footprints for consumer and commercial applications such as: dishwashers, washing machines, coffee and espresso makers, ice makers, steam tables, car wash water sources, and steamers.

摘要： 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.

摘要： A water-on-water filtration system that includes a filter member and two storage vessels. The system includes a plurality of valves that are controlled to place a first of the storage vessels in a fill state in which the first storage vessel is being filled with filtered water, and concurrently place the second of the storage vessels in a service state in which filtered water held in the second storage vessel is delivered as an output of the filtration system. The filtration system can be configured to supply a constant output of filtered water to meet a constant demand while using a relatively small filter member and relatively small storage vessels.

摘要： Provided are water purification systems that are suitable for retrofitting clay pot gravity feed systems. In general, the systems comprise a typical clay pot gravity filter with upper (treatment) and lower (filtrate) chambers, a filter block, such as a gravity flow carbon block, and a flow barrier to prevent or allow water in the upper chamber from contacting and flowing through the block. The system could also include an optional membrane filter. Water is added into the top chamber while the flow barrier is closed so that the water cannot contact or flow through the carbon block. A treatment agent such as chlorine is added to the water to disinfect. After an appropriate contact time, the flow barrier is opened to allow water to flow through the carbon block to the lower chamber. The filter block can remove cysts and chlorine, producing microbiologically safe water. An optional membrane can be added downstream of the carbon block for improved reduction of microbes and particles.

A first aspect of the invention provides methods of making a filtration matrix comprising: mixing an adsorptive media with a polymeric binder to form a mixture; impulse filling a mold with the mixture; and processing the mixture to form the filtration matrix. Filtration matrixes formed from this method are also provided. Another aspect includes methods of making a filtration matrix comprising: mixing adsorptive media with a polymeric binder to form a mixture; filling a mold with the mixture; and applying heat and pressure the mixture to form the filtration matrix, wherein the step of applying pressure to the mixture comprises compressing the mixture until a desired final shape of the filtration matrix is obtained.

摘要： 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.

摘要： 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.

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.
