摘要: A hybrid method and system of treating wastewater with reduced energy usage is disclosed. The treatment system has a sorption system, an anaerobic digester that digests or converts at least a portion of the solids or sludge from the sorption system, and an aerobic treatment tank that partially reduces oxygen demand of a portion of the sludge from the sorption tank.

摘要: Waste-treatment processes are enhanced through generation and introduction of specific biological populations customized to perform or favor specific tasks either during the main process, for the formation or precipitation of certain biological nutrients, or to accomplish solids formation reduction in a post-treatment process. These bacteria may be grown from specialized mixes of activated sludge and waste influent by exposing these materials to controlled environments (e.g., in an off-line treatment area). They may then be returned to the main process to perform certain tasks such as converting particulate cBOD into soluble cBOD for utilization, to reduce high solids yield organisms by supplementing the population characteristics with low yield organism characteristics, to provide biological nutrients or oxygenation assistance, to improve nitrification/denitrification efficiency, or to disfavor filamentous biology such as Norcardia sp.

摘要: Systems and methods for treating water containing PFAS are disclosed. Plasma activated excited gas is encapsulated with nanobubbles in water comprising PFAS to be treated. Liquid-phase reaction of the PFAS with the encapsulated plasma activated excited gas at the air-water interface of the nanobubbles is promoted. The PFAS can be concentrated upstream of the plasma reactor. A foam fractionation process may be used in conjunction with the plasma reactor to facilitate PFAS removal.

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.
