Abstract: A water treatment system can generate ozonated water using a vacuum operated injector with reduced vacuum switch lockup. The water treatment system includes an ozone generator, an ozone injector, a vacuum switch, and a pressure regulator. The ozone generator is configured to generate ozone. The ozone injector is coupled to the ozone generator via a hermetically sealed tubing, and the ozone injector is configured to inject the ozone into a water flow passing through the ozone injector. The vacuum switch is configured to operate the ozone generator based on a gaseous pressure inside the hermetically sealed tubing generated by the ozone injector. The pressure regulator is configured to regulate the gaseous pressure inside the hermetically sealed tubing to prevent the vacuum switch from trapped in a triggered state after the water flow stops.

Abstract: An apparatus is configured to introduce ozone into water. The apparatus includes an ozone source that is configured to provide ozone. The apparatus further includes an air pump that is operatively coupled with the ozone source to provide an air stream mixed with the ozone at a pressure greater than atmospheric pressure. The apparatus further includes an ozone distributor pneumatically coupled with the air pump to introduce the ozone-mixed air stream into the water. The ozone distributor includes a porous tube set in a tortuous configuration.

Abstract: A water treatment system using ozone is disclosed. The system includes a container for holding water, an ozone supply configured to supply ozone, and a water treatment device secured at a lower portion of the container. The water treatment device is configured to disinfect the water using ozone in the container. The water treatment device includes a housing having a plurality of openings and a tortuous porous tube in the housing. The tortuous porous tube is configured to receive the ozone from the ozone supply and distribute the ozone into the water.

Abstract: A pressure washing system uses two-stage ozonation. The pressure washing system includes a container for holding water; a first ozone supply for supplying ozone to ozonate the water in the container in a first ozonation process; a pressure pump configured to pressurize the ozonated water; a second ozone supply for supplying ozone to further ozonate the water to generate two-stage ozonated water in a second ozonation process that is different from the first ozonation process; and a sprayer configured to receive the two-stage ozonated water.

Abstract: A portable water treatment system using ozone is disclosed. The portable water treatment system includes a collapsible container for holding water; a removable cover on an open end of the collapsible container, the removable cover having an opening configured to receive the water into the collapsible container; a filter positioned at the opening of the removable cover and configured to filter the water entering the collapsible container; and a water treatment device configured to disinfect the water in the collapsible container using ozone, the water treatment device comprising a tortuous porous tube configured to distribute the ozone.
