A set-up to be implemented in a water/beverage system for adding flavors, minerals, and/or nutritional supplements to beverages. The set-up comprises a sealed capsule containing said flavors, minerals and/or nutritional supplements. The capsule comprises a container with an upper wall and a bottom wall that are either tearable and/or dissolvable when subjected to a stream of fluid and/or to a pressure/force exerted thereon, and a housing for securely holding the capsule in the water/beverage system.

An electrode apparatus and method remove a polarized molecule in a fluid. In another aspect, a non-uniform electric field is created between an anode and a cathode, the fluid flows within a gap between the cathode and the anode, and the polarized molecule is driven by an electrostatic force to and adsorbed on the anode without experiencing a chemical reaction.

A shower filter includes a water treatment gel composition containing 100 parts by weight of vitamin C or a vitamin C derivative, 100 parts by weight of salt, and 3 to 13 parts by weight of xanthan gum so that there are advantages of removing chlorine dissolved in service water and simultaneously providing natural minerals to skin to help skin care.

A shower filter assembly includes a manifold having an external inlet and outlet, and internal inlet, and an internal inlet and outlet. The external outlet is fluidly connectable to the showerhead. An internal flowpath extends between the internal inlet and the external outlet. A manifold collar extends around the internal outlet and the internal inlet. A filter cartridge is engageable with the manifold, and includes a housing having a filter inlet and outlet. The filter inlet is placeable in fluid communication with the internal outlet on the manifold, and the filter outlet is placeable in fluid communication with the internal inlet on the manifold. The housing is sized to at least partially extend beyond the manifold collar when the housing is connected to the manifold. The filter cartridge has a flowpath from the filter inlet, through a filtration element, and then through the filter outlet.

A point-of-use (POU) water filtration device has a container. A plurality of channels is formed within the container, water entering the container flowing through the plurality of channels. A plurality of Ultraviolet (UV) Light Emitting Diodes (LEDs) is provided. Each of the plurality of UV LEDs illuminating UV light down an associated channel of the plurality of channels.

A water filter includes a housing, a spoiler unit, a power generation unit, a sterilization unit and a purification unit. The housing includes an input portion, an output portion and a first thread portion. The spoiler unit is provided in the housing and corresponds to the input portion. The power generation unit is provided in the housing and is coupled to the spoiler unit. The sterilization unit is provided in the housing and is electrically connected to the power generation unit, and includes a sterilization light source. The purification unit is provided in the housing and corresponds to the output portion and the sterilization unit, and includes a plurality of purification particles. Thus, the water filter is enabled to be coupled to a faucet using the first thread portion, allowing tap water to flow toward the direction from the input portion to the output portion.

A portable water conditioning system is provided that includes a water conditioner, a first sensor, a second sensor, and a controller. The water conditioner has a plurality of conditioning stages that condition water. The plurality of conditioning stages include, in a direction of flow of the water through the water conditioner, a reverse osmosis stage and a deionizing stage. The first sensor detects a first condition of the water before the reverse osmosis stage. The second sensor detects a second condition of the water after the reverse osmosis stage. The controller is in communication with the first and second sensors and determines a health status of the reverse osmosis stage based the first and second conditions. The first and second conditions each include a level of total dissolved solids of the water.

A water softener regeneration system for a water softener configured to soften and filter water, the regeneration system includes a water hardness measurement system configured to determine a hardness value of water flowing out of the water softener. A brine tank is in communication with the water softener and operable to regenerate the water softener with brine from the brine tank. A controller is operable to control the brine tank, wherein the controller actuates by one of opening and closing the brine tank based on the hardness value which is indicative of the effectiveness of the water softener.

A water purification system includes a water inlet for delivering feed water, a membrane having an upstream side and a downstream side, and a water outlet for drawing permeate out of the system. The system includes a plurality of valves operable to control a flow path of feed water, the permeate, and impure water through the system, and a drain in connection with the upstream side and configured to receive the impure water and impurities from the feed water. The system includes a tank configured to receive permeate from the downstream side of the membrane and to store a standby volume of the permeate for delivery to the outlet during an initial portion of a water draw, and a control system for manipulating the plurality of valves.

The invention relates to a method for operating a water filter cartridge in a pipe, said water filter cartridge having a housing in the form of a pressure vessel, and an inlet and an outlet for water, characterized in that a main flow of water to which minerals are added is conducted through a main pipe inside the pressure vessel, and a dosing flow of concentrated salt solution is conducted through a dosing pipe, wherein the dosing pipe branches off from the main pipe and passes through a reservoir of constant volume and in which there is a concentrated salt solution consisting of sulphate salt, chloride salt and/or hydrogen carbonate salt, wherein the part of the dosing pipe extending from the reservoir leads into the main flow at a dosing point through a dosing opening with a constant flow cross-section, and wherein a resistance section which is situated upstream of the dosing point in the main flow is used to set the flow resistance in the main flow such that a pressure difference results between the main flow and the dosing flow and causes a volumetric flow rate of the dosing flow of salt solution which is substantially proportional to the main flow, through the dosing opening opening into the main flow.
