摘要： A process for operating an electrochemical desalination device for desalination of a liquid, the process comprising the steps of: (a) monitoring one or more parameters over time during desalination of the liquid; (b) calculating the average relative change versus time (S) of the one or more parameters; (c) generating a trigger when the average relative change versus time (S) of the one or more parameters exceeds a predetermined threshold value; and (d) flushing the electrochemical desalination device in response to the trigger.

摘要： Apparatuses for the generation of carbon dioxide and hydrogen from a water having a carbonate species are disclosed. The apparatus includes an anodic compartment having an anode disposed on a first side of the anodic compartment and a cathodic compartment having a cathode disposed on a first side of the cathodic compartment. The apparatus further includes a first cation permeable fluidic separator disposed on a second side of the anodic compartment and a second cation permeable fluidic separator disposed on a second side of the cationic compartment. A center compartment is defined between the first cation permeable fluidic separator and the second cation permeable fluidic separator. The apparatus further includes a flow control system configured to independently control flow of water through each of the anodic compartment, the cathodic compartment, and the center compartment. Methods of generating hydrogen, carbon dioxide, and oxygen from seawater using the apparatus are also disclosed.

摘要： An illustrative expendable or reconstructable ozone generator cartridge (100) for an aqueous ozone delivery device (10), for example, for antimicrobial sanitizing, and/or medical treatment, includes a housing (102) for a water treatment manifold (140) providing parallel and operably fixed water pathways (302a-d) through ozone generating cells (210a-d) coupled to the manifold (140), and optionally a data logging and authentication feature.
