  • Patent number: 7022225
    Abstract: An apparatus and system for mixing and separating ozonated water is provided. The apparatus is especially useful as a component of a system for cycling sanitizing ozonated water to a body of water such as a pool, spa or pond. The apparatus generally includes a separating vessel including a mixing tower, preferably located substantially entirely within the separating vessel and including a diffuser element for enhancing mixing of ozonated water without increasing turbulence in the separating vessel. Preferably, the apparatus includes a seal mechanism that substantially prevents liquid water from escaping the separating vessel with vented off-gas. The invention further provides an ozone destruct assembly including a condensate collection portion, and may also include a return line for passing a treated off-gas into the body of water.

  • 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.
