  • Publication number: 20060027463
    Abstract: Apparatus for sanitizing water generally includes a line for receiving a flow of water and an injector assembly for introducing an ozone containing gas into the flow of water to produce a first ozonated water having an increased oxygen concentration relative to the flow of water being passed to the injector assembly. The apparatus further includes an electrolytic device, for example, an electrolytic chlorinator cell, positioned to receive the first ozonated water from the injector assembly. The electrolytic device is effective to produce, from the first ozonated water, a second ozonated water including one or more biocidally effective substances other than oxygen gas. The second ozonated water includes biocidally effective substances, for example chlorine, hydroxyl radicals, and/or other effective oxidizing substances.

  • Publication number: 20050163678
    Abstract: An apparatus is provided for therapeutic treatment of a body part for example, adult human feet, utilizing ozonated water. The apparatus includes a container holding a quantity of ozonated water and sized to contain a body part, for example at least one adult human foot. The apparatus further includes a cover secured to the container, an ozonated water generating system mounted to the container and an ozone destruction assembly for reducing undissolved ozone released from the ozontaed water in the container. The ozonated water generating system includes an ozone gas generator positioned to pass ozone gas into a stream of water being drawn into a water pump. Mixing of ozone gas and water flowing through the pump occurs in the water pump and this therapeutic ozonated water mixture is passed into the container.

  • Patent number: 6817541
    Abstract: An ozone system for agricultural applications generally includes a water flow line having an inlet for receiving a flow of clean water from a water source, an ozone injector suitable for producing a high concentration of ozone in oxygen, and a venturi injector for injecting the ozone gas into the water flowing through the flow line to produce an ozonated water stream. In addition, the system includes a degassing assembly for separating and removing undissolved ozone gas from the ozonated water stream and an ozone destruct assembly adapted to destroy the undissolved ozone. The entire system is motorized vehicle mountable to provide ease in applying the ozonated water stream from the system to agricultural crops.

  • Patent number: 6499671
    Abstract: An ozone system for agricultural applications generally includes a water flow line having an inlet for receiving a flow of clean water from a water source, an ozone injector suitable for producing a high concentration of ozone in oxygen, preferably from oxygen-enriched air, and a venturi injector for injecting the ozone gas into the water flowing through the flow line to produce an ozonated water stream. The system preferably including a spray assist assembly which provides a stream of gaseous component to assist in dispensing the ozonated water fro agricultural application. The entire system, or at least a substantial portion of the system, is mountable on a motorized vehicle to provide ease in applying the ozonated water stream from the system to agricultural crops, particularly living grapevines.
