A disinfection system for treating water. In a specific example, the system treats water prior to its upload to an aircraft or other passenger transportation vehicle. One or more replaceable filters are positioned within a filter chamber housing in order to expose water flowing through the system to filtration treatment.

A water sanitization cap for covering a bottle is provided. The cap may include an ultraviolet-C (“UV-C”) light emitting diode (“LED”) housing and a shell. The shell may be adjacent to a portion of the housing. The cap may also include a waterproof compartment formed within the interior of the housing. The waterproof compartment may include one wall formed at least in part from a transparent material. The cap may include a UV-C LED. The UV-C LED may be fixed within the waterproof compartment, proximal to one end of the UV-C LED housing and oriented to shine light through the transparent material. The cap may include a sensor that when activated, applies a voltage to the UV-C LED to cause the UV-C LED to emit light. The cap may include a cartridge cage that can hold a cartridge. The cartridge cage may be removably attachable to an inner surface of the shell. The waterproof compartment wall may be positioned relative to the cartridge cage such that the UV-C LED, in use, treats water within the bottle before the water flows through the cartridge cage.

The single-hand-operable micro water purifier of the present application relates to a micro water filter, especially a micro water purifier which can filter water by means of pressuring. It consists of a micro filter device and a raw water pressurizing device. The micro filter device consists of a filter cylinder body, a filter water inlet, and a filter water outlet and a filter material assembly located in the filter cylinder body. The raw water pressurizing device consists of a pressurizing device water inlet, a pressurizing device main body, and a pressurizing device water outlet. The present application can promote the raw water to enter the filter device for performing the filtration to obtain the clean water, by using a single hand to operate, which not only brings convenience to the user, but also saves labor and improves the use efficiency.

A portable water treatment system comprising a water processing unit that automatically determines whether the system is connected to a pressurized water source or not. If an unpressurized source is detected, the system activates a pump to ensure that the water flows through the system at a pressure level to remove particulates and ensure the ultraviolet (UV) light is effective at neutralizing viruses and bacteria. If the water source is pressurized, the pump is deactivated and the water flows through the system under the pressure of the pressurized source. The system uses a failsafe mechanism to 1) ensure that water cannot flow through the water treatment unit if the UV light chamber is not powered and 2) ensure the user can know that the UV light is in fact functioning through the use of an indicator.

Illustrative configurations of a pet hydration system and methods are disclosed. The pet hydration system includes a bowl section configured to temporarily store water therein. In one configuration, a hydrogen-generation assembly is positioned in the bowl section. The hydrogen-generation assembly generates and introduces hydrogen into the water temporarily stored in the bowl section. In other configurations, methods related to pet hydration are also disclosed.

A filtration apparatus for a container, the apparatus includes a connection portion for securing the apparatus to the container; a housing; a hand pump attached to the housing, the hand pump comprising an inlet, an outlet, and a user-operated actuator, the hand pump is configured to pass filtered water through the inlet in a first direction towards the outlet of the hand pump during a first stroke of the user-operated actuator, and in both the first direction and in a second direction opposite to the first direction during a second stroke of the user-operated actuator; and a filter fluidly connected to the inlet of the hand pump, the housing is configured to house the filter and at least part of the hand pump, the housing is configured to pass water, the filter is configured to be a two-way valve for regulating water flow between the housing and the hand pump.

A universal water purification system and method that can desalinate salt water or just filter fresh water. Preferably, the system is portable and relatively lightweight and provides for emergency or recreational safe power and water accessibility. The components of the system can be installed on an aluminum frame and preferably include a waterproof front control panel, four pre-filters, a reverse osmosis membrane, ultraviolet (UV) LED lamp, a high pressure reverse osmosis (RO) pump and a low pressure water supplying pump, an electro valve preferably with a manual override in case of power loss, an additional electro valve, a plurality of quick connect couplings (preferably three), a power bank, an internal inverter, a universal power supply and battery charger preferably disposed within a military style suitcase. In a preferred embodiment, the suitcase can be a PELICAN brand case. The system can provide a power bank, universal power supply (12V, 24 V, 90-260V 409-70 HZ), wide range battery charger, and water filtration and desalination unit for both outdoor and indoor applications.

A drinking cup filter assembly for inhibiting a user's mouth from contacting a drinking cup includes a shield that has a first portion being spaced from a second portion to define a cup space between the first and second portions. The shield can be suspended on a lip of a drinking cup having the lip being positioned in the cup space. The first portion and the second portion inhibit a user's lips from contacting the drinking cup when the user drinks. The first portion has a plurality of fluid inlets and a fluid outlet to pass a beverage in the drinking cup through the fluid inlets and the fluid outlet. In this way the user can drink the beverage. A filter is removably positioned within the first portion of the shield to filter the beverage.

In one aspect, a modular filter assembly for filtering fluid that flows in a flow direction therethrough is disclosed. The assembly includes a first housing section having a first filter element; a second housing section having a second filter element; and a connector disposed between the first and second housing sections. A housing includes the first housing section, the connector, and the second housing section. The flow direction is through the first and second filter elements in series.
