The 70% water from the RO water purification process that fails the drinking water standard is recycled through the RO waste water recycling device. The low-temperature water source is connected to an antichlor device and the water is therefore dechlorinated. The first and second ozone modules are used to produce ozonated water and to release ozone through the aeration pipe assembly into the kitchen cabinet for deodorization and sterilization.Type: GrantFiled: October 4, 2010Date of Patent: October 1, 2013Assignee: Cashido CorporationInventors: Shih-Chang Chen, Tsair-Rong Chen, Shih-Chien Tsai, Chun-Lung Chiu, Chih-Chung Cheng, Che-Wei Hsu

Publication number: 20130206704Abstract: A system is described herein which provides an ozonated liquid. The system comprises a liquid inlet arranged to continuously accept a liquid into the system at a desired flow rate; a liquid outlet to dispense ozonated liquid out of the system, the ozonated liquid having an oxidation-reduction potential of at least 450 mV due solely to ozone dissolved in the liquid, the liquid outlet being in fluid communication with the liquid inlet and arranged to dispense the ozonated liquid out of the system at the desired flow rate. The system has a tank-less ozonation flow path between the liquid inlet and the liquid outlet, the flow path adapted to ozonate the accepted liquid, producing the ozonated liquid to be dispensed out of the system. The accepted liquid has a fluid residence time in the ozonation flow path of less than 5 minutes prior to being dispensed as the ozonated liquid.Type: ApplicationFiled: November 1, 2011Publication date: August 15, 2013Applicant: TERSANO INC.Inventors: Steve L.

Publication number: 20130206654Abstract: An apparatus has a hub including a water inlet for receiving source water, a water outlet for discharging ozonated water, and an interface between the water inlet and the water outlet. The apparatus also has a cartridge including an electrolytic cell for ozonating the source water. The electrolytic cell has a cathode, an anode comprising diamond, and a membrane between the cathode and the anode. The electrolytic cell is configured to flow source water through both the cathode and the anode. The cartridge further includes at least one cartridge port for removably coupling with the interface on the hub. The at least one cartridge port and the interface are configured to flow source water from the hub into the electrolytic cell and to flow ozonated water from the electrolytic cell into the hub.Type: ApplicationFiled: September 7, 2012Publication date: August 15, 2013Applicant: ELECTROLYTIC OZONE INC.Inventors: Carl David Lutz, Jeffrey D.
