APPARATUS AND METHODS FOR DISINFECTING A SURFACE

摘要

The invention relates to improvements in surface disinfection apparatus and methods and in particular to apparatus and methods which may be used to disinfect wounds using high concentration aqueous ozone. The method comprises the steps of flushing an ion exchange means with fluid from a fluid supply and directing the flushing fluid to waste; de-ionising fluid from the fluid supply by passing it through the ion exchange means and directing the process fluid to storage means; and purging the ion exchange means with gas to remove residual process fluid after the de-ionisation process has been completed.
