    摘要： An amount of a first reactant, such as degradable wastes like stool and toilet paper from waste disposal systems, is provided as a liquid influent to a reactor. A gaseous influent stream providing a second reactant, e.g., air, is also provided for reaction with the first reactant. The reaction produces a solvent-laden gaseous effluent that is removed. The reactor can include a plurality of thermophilic bacteria with the influent stream of air configured to aerate the biomass and enable aerobic digestion of wastes. Solvent in the removed effluent, e.g., water, can then be condensed and isolated therefrom. Condensate isolated in this manner has been shown in achieve at least 28 mg/L chemical oxygen demand (COD) and 1.2 mg/L total suspended solids (TSS) from consumer human waste influent. The effluent can be recycled to achieve nearly the same rate of COD removal at greatly reduced power consumption.

    摘要： The disclosure relates to waste water treatment. A flow of an aqueous solution comprising a chloride salt is electrolysed between an anode and a cathode of an electrolysis cell. The flow of aqueous solution is separated from the anode by a first ion-exchange structure and from the cathode by a second ion-exchange structure. A first auxiliary flow of liquid is driven through a first auxiliary region between the anode and the first ion-exchange structure during the electrolysis. A second auxiliary flow of liquid is driven through a second auxiliary region between the cathode and the second ion-exchange structure during the electrolysis. The first auxiliary flow, or liquid from the first auxiliary flow, is used to treat waste water.

    摘要： The invention relates to a system and method for treating wastewater onboard a marine vessel or other limited space application where wastewater treatment is required. In one embodiment of the invention, two polar opposite wastewater treatment processes are incorporated into the same treatment system. The system is a hybrid treatment unit that combines a conventional wastewater treatment using a moving bed biofilm reactor (MBBR) process-based biological treatment unit in combination with a novel electrochemical advanced oxidation process (EAOP) via an in-situ sodium hypochlorite recirculation. The clarified and disinfected effluent from this hybrid treatment unit is filtered to remove residual TSS. The filtered and disinfected effluent is discharged after dechlorination/neutralization. On-site maintenance disinfectant can be produced via the electrochemical/electrochlorination/electro-oxidation process and used for both treatment unit cleaning and disinfection. Additionally, the treatment unit provides a wholly separate stream of electrolysis generated disinfectant for surface disinfection purposes.

    摘要： The technology disclosed relates to a method, a system, and a wastewater treatment system comprising a biological treatment zone for biologically treating fat, oil and grease by adding a culture of microorganisms for partial biodegradation of the fat, oil and grease and/or breaking down the fat, oil and grease. The wastewater system may then comprise a control system, an air injection and distribution system for improving and controlling the biological treatment process and at least one sensor. The at least one sensor may be configured to obtain sensor data, audio data and/or image data, and the control system may be configured to determine the thickness of a layer of fat, oil and grease on the surface of the biological treatment zone.

    摘要： Disclosed herein is a method for remediating sewage that contains persistent contaminants. The method comprises ozofractionating the sewage under conditions whereby a foam fractionate comprising persistent contaminants is produced and separated from an ozofractionated wastewater, quiescing the ozofractionated wastewater, whereby a residual ozone content of the ozofractionated wastewater is reduced, and contacting the quiesced ozofractionated wastewater with a microorganism population under conditions effective to biologically remediate the ozofractionated wastewater.
