Abstract (en)

[origin: WO0058223A1] A water treatment apparatus which comprises an inlet for unpurified water, a boiler (4) for purifying water by heating, a heating means (5) for heating the water in the boiler (4), and an outlet for purified water. The transport of water through the apparatus takes place by means of, respectively, an overpressure and an underpressure, which originate in the boiler (4) during, respectively, a first and a second phase of a heat-exchanging process. The first phase of the heat-exchanging process comprises heating of the water in the boiler (4) until a predetermined temperature is reached, and maintaining this temperature during a predetermined period of time. The second phase of the heat-exchanging process comprises condensation through cooling of vapor, until a predetermined temperature is reached, said vapor being generated by heating the water during the first phase. By virtue of the above-mentioned way of transporting water through the apparatus, the water treatment apparatus does not need a pump or a continuous connection to the water main for transporting water.
