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 and filter material for providing or treating potable water is provided. The filter includes a housing having an inlet and an outlet, a filter material disposed within the housing, the filter material formed at least in part from a mixture of a plurality of mesoporous and microporous activated carbon particles. Preferably, at least some of the mesoporous activated carbon filter particles are coated with a cationic polymer, and even more preferably, at least some of the particles are coated with a cationic polymer and silver or a silver containing material. Kits comprising filters and information relating to the reduction, killing or removal of bacteria, viruses, microbials, and TTHM are also provided.

Abstract: Provided are electrochemical devices that are rechargeable, where an electrolyte stream whose electrolyte is electrochemically inert is supplied to an ion concentrate compartment between a bipolar membrane and an electrode, thereby eliminating a potential for scale build-up. When strong or weak cation resins are used in a product compartment of an electrochemical device, acid water produced can be used to soak and clean an ion concentrate compartment next to an electrode, such as the cathode.

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.

Abstract: 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.
