Abstract
In one embodiment, a liquid purification system for purifying a liquid and delivering purified liquid to external downstream equipment includes a source of liquid to be purified and a filter device that is operatively coupled to and selectively in communication with the source of liquid. The filter device includes a filter element. The system also includes a controller and a means for performing a filter integrity test on the filter element, whereby the controller is configured to detect when purified liquid is being used by the downstream equipment and coordinate the initiation of the filter integrity test at time when conducting the filter integrity test does not adversely effect the operation of the downstream equipment.
