Abstract: A system for upgrading raw water using a filter, for eliminating intrinsic factors of such water. Optionally the system includes a device for facilitating sustained release of extrinsic factors supplied by one or more capsules. Optionally the system includes also a dosing device for prolonging the constant supply of extrinsic factors to the drinking water to a period of time beyond that which is facilitated by one capsule laden with the factors. The filter of the system forces the gravitationally trickling raw water to meander through a path in which it reacts with a set of reactants. Upgraded after having passed through the filter, the water is collected and made available for dispensing through a spout. Optionally, one or more capsules laden with health promoting, nutritive, remedies or other beneficial factors are added to the upgraded water. A number of techniques for facilitating a substantially constant addition of vitamins, minerals, and other beneficial chemicals is described.

Abstract: A water treatment device and method for treating a quantity of water is powered by gravitational flow. The device includes an upper collecting chamber (14) and a filtration chamber (18). The filtration chamber includes a set of reactance containg at least three components wherein one of the components is a polycation and another one of the components is a polyanion. The method includes subjecting the water to gravitational flow through the filtration chamber (18).
