摘要： A high-concentration wastewater treatment device includes a discharge pin module including a support plate, discharge pins coupled to the support plate, and pin connectors connected to the discharge pins and extended upwards, a discharge plate module spaced apart from the discharge pins, and a circuit module including a main board, distributed processing boards connected to the main board, coupling unit connecting the distributed processing boards, and discharge pin connection portions electrically connected to the distributed processing boards in a direction of a lower end of the main board. The discharge plate module includes a connection pin connected to a lower end of the support plate and a discharge plate accommodation portion coupled to a lower end of the bent portion. The discharge pin connection portions have, at lower ends, coupling grooves into which the pin connectors are inserted, to allow one-touch coupling between the circuit module and the discharge pin module.

摘要： There are provided processes for treating wastewater. The processes can comprise treating a mixture comprising the wastewater and an activated sludge, in a single reactor, with an electric current having a density of less than about 55 A/m2, by means of at least one anode and at least one cathode that define therebetween an electrical zone for treating the mixture; exposing the mixture to an intermittent ON/OFF electrical exposure mode to the electric current in which an OFF period of time is about 1 to about 10 times longer than an ON period of time; and maintaining an adequate oxidation-reduction potential in the single reactor. Such processes allow for substantial removal of carbon, nitrogen and phosphorus from the wastewater in the single reactor of various forms and for obtaining another mixture comprising a treated wastewater and solids.

摘要： The present invention consists of a method of pre-treatment of adulterated water for distillation, including adulterated water produced during hydraulic fracturing (“fracking”) of shale rock during natural gas drilling. In particular, the invention is directed to a method of treating adulterated water, said adulterated water having an initial level of bicarbonate ion in a range of about 250 ppm to about 5000 ppm and an initial level of calcium ion in a range of about 500 ppm to about 50,000 ppm, said method comprising contacting the adulterated water with a non-thermal arc discharge plasma to produce plasma treated water having a level of bicarbonate ion of less than about 100 ppm. Optionally, the plasma treated water may be further distilled.

摘要： A wastewater plant and method for treatment of wastewater sludge or other wastewater fluids are described. The wastewater plant utilizes an electrical discharge system configured for receiving a wastewater fluid, and generating a transient voltage and arcing electric current pulse through the received wastewater fluid to create an electro-hydraulic shock wave within the wastewater fluid accompanied by a high electric field, intensive heat and light radiation.

摘要： Methods and systems for reducing a redox active contaminant in a waste stream in a waste treatment system involve performing a unit process of the waste treatment system by contacting redox active contaminant in the waste stream with oxyhydrogen-rich gas generated on-site by an oxyhydrogen gas generator that implements water dissociation technology. The oxyhydrogen gas generator involves applying a pulsed electrical signal to a series of closely spaced electrodes that are submerged in the waste stream to produce oxyhydrogen-rich gas from a water component of the waste stream. Operation of the oxyhydrogen gas generator in the waste stream may accomplish one or more unit processes for waste treatment, such as oxidation, stripping, floatation, disinfection, conditioning, stabilization, thickening, and dewatering, among others.

摘要： A system and method for treating flowing water systems with a plasma discharge to remove or control growth of microbiological species. The system and method protect other components of the water system from being damaged by excess energy from the electrohydraulic treatment. The system and method also recycle ozone gas generated by a high voltage generator that powers the plasma discharge to further treat the water. A gas infusion system upstream of or inside a plasma reaction chamber may be used to create fine bubbles of ozone, air, or other gases in the water being treated to aid in plasma generation.
