A bottle generally includes a container body, a lid assembly, a filter, and an air pump. The container body defines therein an inner space. The lid assembly includes a top cover and a base portion, between which a chamber is defined. The base portion defines a first port and a second port. An outlet tube is connected to the first port at one end and extended out of the chamber at another end. The filter is located in the inner space of the container body and connected to the first port. The air pump is disposed in the chamber of the lid assembly and connected to the second port by an air tube for supplying air into the inner space of the container body to force the water contained in the container body to pass through the filter and flow out of the bottle via the outlet tube.

A water container or bottle with integrated disinfection preferably includes a battery compartment, a control printed circuit board (PCB) to manage several parameters including timing, voltage rate, and user-interface. A high voltage power supply is coupled to a set of electrodes to cause an electric discharge. The electric discharge results in a series of reactions in the water that eliminate bacteria and viruses, dissolves organic material, and oxidizes inorganic compounds.

The present invention refers to lightweight and settable photocatalytic compositions and solid composites; methods of preparing the compositions and solid composites; and their use in water purification. The compositions are comprised of photocatalysts such as titanium dioxide (TiO.sub.2) and zinc oxide (ZnO), lightweight glass bubbles, and a hydraulic cementing binder. The lightweight and settable photocatalytic compositions can be formed into lightweight photocatalytic solid composites and/or structures by mixing with water and moist curing. This invention also describes relatively simple, fast, and cost effective methodologies to photodope the TiO.sub.2ZnO compositions and composites with silver (Ag), to enhance and extend the photocatalytic activity from the ultraviolet into the visible light spectrum. The lightweight and settable TiO.sub.2ZnO and AgTiO.sub.2ZnO compositions are used in making solids, structures, coatings, and continuous or semi-continuous water purification panels for purifying contaminated water.
