A water purification cap for covering a water bottle is provided. The cap may include a barrel and a shell. The shell may surround a first end of the barrel. The cap may include a charging site. The charging site may be integral to the shell. The charging site may include a positive pole, a negative pole and an RGB ring. The RGB ring may insulate between the positive pole and the negative pole. The RGB ring may display colors that indicate a status of the cap. The cap may include a UV-C LED. The UV-C LED may be proximal to a second end of the barrel. The light emitted from the UV-C LED may be UV-C rays. The UV-C rays may be in the range of 100-280 nanometers. The cap may include a touch sensor. When touched, the touch sensor may activate the UV-C LED.

The invention provides an electrolytic cell and, more precisely, an electrolytic cell for the production of disinfecting liquids and detergents, the cell has a cylindrical tubular construction and wherein the cathode and the anode are arranged coaxially one with respect to the other, and wherein the anode has a conical shape. The invention furthermore also provides the operating method of the aforesaid electrolytic cell for the production of the aforementioned disinfectant and detergent liquids.

A particle filtration system that includes first, second and third filter segments that each include several first, second and third filters. Each first, second and third filter includes a fibrous layer sandwiched between a pair of surface or outer layers. The range of pore sizes of each first, second and third filter varies according to the density of the surface layers relative to the fibrous layers.

The invention relates to a filter device (100), particularly a filter cartridge (10), for water filters in aircraft comprising a housing (11), wherein the housing (11) comprises an entry region (12) for water to be filtered and a discharge region (24) for filtered water, and wherein a first filter unit (26) and a second filter unit (27) are arranged in the housing (11). The first filter unit (26) comprises an activated charcoal filter (28) and the second filter unit (27) comprises a microfilter (30).

Systems and methods are disclosed herein for ion exchange wherein process fluid is injected at multiple points within the ion exchange vessel simultaneously, allowing the contaminants and/or the contaminated process fluid to be distributed homogeneously throughout the ion exchange media. These systems and methods may be implemented in one or more of fixed, mobile, and modular embodiments.

The present disclosure relates generally to reactor systems that include (a) a housing having an interior surface that may be at least partially reflective, (b) at least one reactor cell disposed within an interior of the housing, the at least one reactor cell including an enclosure and a plasmonic photocatalyst on a catalyst support disposed within the at least one enclosure, where the enclosure is optically transparent and includes at least one inlet for a reactant to enter the at least one cell and at least one outlet for a reformate to exit the at least one cell and (c) at least one light source disposed within the interior of the housing and/or external to the housing. At least one light-management feature and/or at least one thermal-management feature is applied to the reactor cell, reactor system, or a reformer system comprising many reactor systems, in order to improve efficiency.

An annular filter includes a first annulus wall and a second annulas wall being impermeable to fluid (liquid and gas), a first circular wall and a second circular wall mounted between the first annulas wall and second annulas wall wherein the first and second circular wall are permeable to fluid (liquid and gas), at least one dividing wall mounted between the first and second circular wall to divide an internal volume defined between the first and second annulas wall and the first and second circular wall into channels, bisecting walls between the first and second circular walls to change a direction of fluid flow from a first direction to a second direction first and second channels, turbulator walls mounted channel, wherein the turbulator walls cause turbulent fluid flow in the channels, and a filter media positioned in at least one of the channels.

The invention relates to preventing microplastics from the entering the environment. In particular the invention is directed to filtering microfibers from the waste water from washing machines as well as waste from other appliances and other sources of effluent with entrained microplastics or other microp-ollutants. A separator is provided for separating microplastics from effluent comprising; a chamber including at least one sieve structure, a shroud that acts as a vortex finder and a baffle coaxial with the shroud and projecting upwards from the lower end of the chamber, wherein the shroud has a circular lower rim and the baffle has a circular upper rim, wherein the radius of the lower rim of the shroud is greater than the radius of the upper rim of the baffle.

An efficient, cost-effective, and efficacious technique for removing coal ash and other pollutants from waterways, ponds, marshes, holding tanks and other water sources and supplies. An apparatus comprising an open cage including electromagnets and/or permanent magnets and/or electrodes is supplied with electrical power to extract materials such as rare earth elements and/or heavy metals. The materials levitate to the surface, forming a slurry while leaving water substantially free of such materials. Rare earth magnets electrically connect electrolysis electrode structures and serve as electrolysis electrode segments.
