Abstract: A waste water treatment system including an electrolysis treatment system and three membrane concentration systems. The electrolysis treatment system includes a first chamber that receives waste water and produces treated waste water, a second chamber that receives first recycled water and produces dilute acid discharge, and a third chamber that receives second recycled water and produces dilute caustic discharge. An anion exchange membrane separates the first chamber from the second chamber. A cation exchange membrane separates the first chamber from the third chamber. The membrane concentration system receives the treated waste water and produces a concentrated aqueous sodium sulfate product and a pure water product. A first thermal concentration system receives the dilute acid discharge and produces first recycled water and a concentrated acid product. The second thermal concentration system receives the dilute caustic discharge and produces second recycled water and a concentrated aqueous sodium sulfate product.

Abstract: The disclosure relates to efficient methods of controlling biological conversions while simultaneously removing and converting some of the generated products. More specifically, and, for example, the disclosure discloses electrochemical processes to remove and capture potentially toxic ammonium during anaerobic digestions and to remove and capture carboxylic acids during bioethanol production. The disclosure can, thus, be used to enhance bioproduction processes via controlling pH and/or reduction/oxidation, in combination with in situ product recovery.

Abstract: A water treatment apparatus of the present disclosure includes an electrochemical cell provided with an inlet and an outlet, a power supply that supplies electric power to electrodes, a first water flow path connected with the inlet, a second water flow path connected with the outlet, a soft water supply unit that feeds soft water to the inlet, and a flow adjustor that regulates a flow rate of water passing through the second water flow path. The water treatment apparatus further includes a controller that controls electric power supplied from the power supply to the electrodes, the flow rate of water passing through the second water flow path by use of the flow adjustor, and soft water fed to the inlet by use of the soft water supply unit when a process for regenerating the electrochemical cell is executed. As a result, the apparatus can reduce the hardness and electric conductivity of water fed into the electrochemical cell during regeneration of an ion exchange membrane and restrain scale formation.

Abstract: For bio-electrically generating electric power from organic ingredients of a waste water flowing in a flow direction, an anode is immersed in the waste water in a first spatial area, and oxygen is supplied to a cathode which is electrically connected to the anode and arranged in a second spatial area delimited from the first spatial area by means of a proton-permeable membrane. A voltage between the anode and the cathode is increased by a DC/DC converter located at the anode and the cathode, and a further voltage between a further anode in said or a further first spatial area and a further cathode in said or a further second spatial area is increased by a further DC/DC converter located at the further anode and the further cathode. A DC voltage link is charged with the DC/DC converter and the further DC/DC converter connected in parallel to the DC voltage link.

Abstract: The present invention relates to a method for treating tritium water-containing raw water, the method including supplying a part of raw water containing tritium water and alkali water to a circulation tank, mixing the raw water with alkali water in the circulation tank to obtain an electrolyte adjusted so as to have a desired alkali concentration, and continuously electrolyzing the electrolyte while circulating the electrolyte, thereby subjecting the raw water stored in the storage tank to alkali water electrolysis and thus gasifying the raw water.According to the invention, by gasifying tritium water-containing raw water by alkali water electrolysis, the tritium concentration in a tritium-containing hydrogen gas is diluted to 1/1,244 and the tritium water-containing raw water can be reduced in volume.
