A kit for purifying water comprises a first container for receiving untreated water, and a second container for receiving purified water and having a dispensing spigot. A water purification composition, when mixed with water in the first container, produces partially purified water having solid matter. A first filter held in a filter holder at an upper end of the second container removes the solid matter when the partially purified water is poured from the first container. A second filter in the second container comprises carbon.

Term end not estimated
The present invention relates to treatment of water and more particularly to kits for purifying water.
There is a need for potable water in all areas of the world. In developed countries, water is purified and potable water is supplied on a large scale, typically by large national or multinational water management companies. This water is typically supplied directly to consumers' homes in a potable form. However, in some parts of the world, for example in some rural areas of developing countries, many people either do not have a direct water supply to their homes and only have access to a non-potable communal water supply such as a village well, or cannot be guaranteed that the water they do receive is potable.
It is known to produce potable water using a flocculent composition. Flocculent is mixed with the source water, typically a number of times, until large particles (“flocs”) are coagulated that include various contaminants. These particles are then removed from the treated water, for example by pouring the water through a filtering material, to produce purified water.
Preferred embodiments of the invention will be described with reference to the accompanying drawings, wherein like reference numerals identify corresponding parts:
FIG. 1 is an exploded perspective view of a first embodiment of a water purification kit according to the present invention;
FIG. 2 is a vertical cross-sectional view of the first embodiment shown assembled without the first container;
First Embodiment
A first embodiment of a water purification kit will be described with reference to FIGS. 1-3. Referring in particular to FIG. 1, kit 10 includes first container 20, filter 30, filter holder 40 and second container 60, and a stirring implement 61.
First container 20 is for mixing a water treatment (“flocculent”) composition. It is preferably 5-20 liters in volume, most preferably 12-14 liters so that a batch of approximately 10 liters can be made. Pour spout 26 is for pouring the partially purified water with flocs out of first container 20.
