<p>A method of providing at least two outlet purified water streams from a water purification system comprises at least the steps of: providing a first purified water 32 into a first reservoir 34 able to provide an outlet purified water stream 36; passing at least a portion of the first purified water from the first reservoir through a water purification process 40 to provide an ultra-purified water stream 46; passing the ultra-purified water stream to a second reservoir 44; providing an excess of ultra-purified water into the second reservoir; allowing the excess ultra-purified water 56 in the second reservoir to flow into the first reservoir; and providing an outlet from the water purification system of an ultra-purified water stream 48 from the second reservoir. In this way, the water purification system has a second reservoir which provides a buffer volume of ultra-purified water immediately available for output through a dedicated line for high purity purposes such as analyser feed, and also a first reservoir of purified water for other less high quality purposes, available as a separate outlet stream. A water purification system is also claimed.</p> |
