摘要： A system for the treatment of phosphate-containing wastewater comprises a pretreatment subsystem including a mixing chamber configured to mix a potassium-based salt with the wastewater to precipitate K2SiF6 from the wastewater, a solids-liquid separator to separate the precipitated K2SiF6 from the wastewater and form a pretreated wastewater, and a mixing chamber to dilute the pretreated wastewater with raw wastewater, and a filtration subsystem including a first filtration configured to receive the pretreated wastewater and remove particles to form a first effluent, a second filtration unit remove divalent ions from the first effluent and form a second effluent, and a third filtration unit configured to remove additional dissolved solids from the second effluent and form a third effluent suitable for discharge to the environment.

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 electrochlorination system comprises a source of feed fluid, a product fluid outlet, and a plurality of electrochemical cells connected fluidically between the source of feed fluid and the product fluid outlet. The system is configured to operate at least one of the plurality of electrochemical cells at one of a first current density or a first flow rate, and to operate another of the plurality of electrochemical cells at a second current density or second flow rate different from the respective first current density or first flow rate.
