Abstract:
1. Water treatment apparatus comprising: a water inlet; a water outlet; first and second water aspirators including respective first and second Venturi tubes through which water can flow, each of said Venturi tubes having a water inlet port, a water outlet port, and a vacuum port, said first Venturi tube being designed for a relatively higher water flow rate and said second Venturi tube being designed for a relatively lower water flow rate, the two Venturi tubes having different minimum water flow rate thresholds, below which the respective Venturi tube will not function; a single three-port valve having two positions for selectively directing water from said water inlet to said water outlet through either said first or said second water aspirator; and an ozone generator having an output connected to said vacuum ports, whereby gas including ozone is drawn either into water flowing through said first Venturi tube or water flowing through said second Venturi tube, depending on the position of said valve.
