<p>A purifier treating a batch of liquid with ozone uses a reversible pump (10) that directs liquid flow along different courses during forward and reverse pumping. In a forward mode, the pump (10) directs ozonized liquid through a purification course that purifies the liquid; and in a reverse mode, the pump (10) withdraws ozonized liquid from the purification course and redirects the withdrawn liquid to a reverse destination, which can be a purified liquid output (30) or a return of the withdrawn liquid to a liquid container (12).</p> |
