The bottom of the electrode holder faces the water inlet. Also disclosed is an ozone electrolysis cell application module.

The present invention relates to a ballast water treatment system including an air compressor for compressing air; an air receiver tank for receiving the compressed air from the air compressor and storing the compressed air; an oxygen generator for generating oxygen from the air supplied from the air receiver tank; an oxygen receiver tank for storing the oxygen supplied from the oxygen generator; an ozone generator for generating ozone from the oxygen supplied from the oxygen receiver tank; a ballast water pump for pumping ballast water; an inflow line for transferring the ballast water from the ballast water pump; a ballast water tank for receiving the ballast water from the inflow line and storing the ballast water; and an ozone injector for injecting the ozone into the ballast water of the inflow line.

A novel system for generating ozonated water, for example, for sterilization of medical equipment. The system comprises an ozone generating cell including a nafion membrane separating an anode, and a cathode enclosed within a cell housing. The cell housing has a cathode housing portion and an anode housing portion separated by the membrane. The housing also incorporates an integrated spectrophotometer including a bubble trap. The system includes a hydrogen water reservoir for receiving water from the cathode and an ozone water reservoir for receiving generated ozonated water from the anode. Control circuitry controls a set of pumps, and controls ozone generation in a closed loop using the spectrophotometer to provide a selected ozone concentration in the ozonated water from the anode. An output port coupled to the ozone water reservoir allows ozonated water to flow out of the system for external use.

An illustrative aqueous ozone sanitizing system for body part, tissue, and instrument sanitizing, including hand rinsing and sanitizing includes a sanitizing chamber, spray devices configured to simultaneously irrigate the entire left and right hand of a user, at least two aqueous ozone generators each fluidly coupled to a subset of the spray devices, and a housing for the sanitizing chamber having an opening for guiding the user's hand orientation and position into the sanitizing chamber.

An illustrative aqueous ozone delivery device for use with an aqueous ozone generator cartridge can be used for body part, tissue, and instrument sanitizing, including hand rinsing, hand sanitizing, and clinical treatment. One embodiment includes a hooded sanitizing chamber and spray devices directed to each hand of a user, a docketing station for pluggably receiving a replaceable ozone generator and sensor cartridge, and a controller for sensing hand position and orientation, delivering a desired ozone concentration and duration.

A water circulation system that includes a pipe assembly for in-line mixing of water and ozone for a recreational or decorative water feature is disclosed. The pipe assembly includes a first flow path for water to flow through. The first flow path includes one or more ozone intake ports that are fluidically coupled to one or more ozone output ports of an ozone supply unit. The pipe assembly further includes a second flow path fluidically coupled in parallel with the first flow path. The second flow path includes a control valve that selectively permits a portion of the water to flow through the second flow path to produce a negative pressure in the first flow path so that ozone is drawn into the first flow path through the one or more ozone intake ports and mixed into the water flowing through the first flow path.

The invention relates to the detection, assessment and mitigation of harmful water-borne bacteria such as cyanobacteria. Multiple apparatus embodiments and variations are described. One apparatus can apply at least one of UV-C irradiation, microbubbles containing ozone and ultrasonic sound to mitigate the harmful water-borne bacteria. The systems and methods of the invention can be applied to bodies of water, including fresh water and salt water, and can be applied to wastewater treatment. The systems and methods of the invention can be used to reduce the concentration of algae directly and can be used to reduce the concentration of nutrients in water that algae use to grow. Methods of mitigation of the harmful bacteria are described that do not involve the introduction of chemicals into the environment.
