Abstract:
The present invention intends to provide a water purification apparatus that is small and easy-to-use, yet being capable of efficiently creating flocs of impurities and removing the impurities from the wastewater in a single pass. To achieve this objective, an inner tubular anode 12 made of stainless steel or carbon is inserted into an outer tubular cathode 11 made of aluminum, leaving a predetermined intermediate space 13 between them, and electrolysis is carried out to produce aluminum hydroxide. The aluminum hydroxide thus produced serves as the medium for flocculating the impurities in the wastewater ascending the intermediate space 13. The wastewater containing the flocs of impurities is filtrated with a filter 18 within a filtering and settling tank 17. As a result, the impurities are completely removed from the wastewater.
Abstract:
Disclosed is an improved water treatment cavitation reactor cone. The tank operates on a continuous flow of fluids which are subjected to ultrasonic waves in combination with a high level of injected ozone. The treatment tank includes a tangential inlet that induces a rotating flow into the tank thereby increasing the mixing of the ozone within the effluent. The effluent is further treated with DC current. The treatment tank provides a cost efficient and environmentally friendly process and apparatus for cleaning and recycling fluids as contaminated as frac water, used to stimulate gas production from shale formations, as well as other types of fluids having various levels of contaminants such as aerobic and anaerobic bacteria and suspended solids. The calcium carbonate scaling tendency is reduced to an acceptable level without the use of acids, ion exchange materials, or anti scaling chemicals which is of economical and environmental significance and benefit.
Abstract:
An atomizing apparatus (10) includes a housing (12), and a tank (40) accumulates tap water inside the housing. By electrolyzing the tap water by the electrolysis electrodes (120p, 120m), the water in the tank becomes electrolyzed water. At the first operation after a shortage of water state in the tank is detected, an initial electrolysis operating time is set to 20 minutes (step S210). In a case of not an operation after the shortage of water state but a restart of a normal operation, the initial electrolysis operating time is set to 5 minutes (step S224).
Abstract:
The invention comprises a method of treating sludges which includes the steps of applying an electric field to the sludge to effect dewatering prior to further dewatering of the sludge. Typically the sludge comprises dilute phase sludge, and the electric field is a DC electric field. The pH of the sludge may be adjusted to between substantially 5 and substantially 6 prior to applying the electric field.
Abstract:
A method for the treatment of fluid including the step of exposing the fluid to a pulsed plasma discharge. The pulsed plasma discharge will be generated using a suitable electrode configuration to generate the plasma discharge in the fluid. Apparatus useful in the method may include a vessel, at least two electrodes for generating a plasma discharge in water, and a flow inlet and a flow outlet to allow water to be passed through the vessel. Also described is an in-line water treatment, where a pulsed plasma discharge is used in a pipe carrying moving water. Plasma based fluid treatment system may have many advantages in comparison to other treatment methods, such as very minimal maintenance, low operating power, and minimal pressure loss through the device.
Abstract:
Provided is a submerged-type, electrosorption-based desalination apparatus for water purification and method, comprising applying a DC voltage of 0.1 to 2.0 volts to a carbon electrode of the reactor to thereby adsorb inorganic ions on the carbon electrode, and reversely applying the same DC voltage having opposite polarity to recycle regeneration solution to the outside of the apparatus or into the treatment tank, thereby enhancing a recovery rate. In addition, in order to improve desalination efficiency, the reactor used in the desalination apparatus may be embodied in various forms of T-shaped, linear type, single, composite, and ion exchange membrane electrodes. Therefore, the present invention may be applied to remove inorganic ions from industrial wastewater, sea water, and brackish water, which contain large amounts of inorganic ions.

A treatment method of organic compounds included in waste water, comprising the steps of: supplying waste water to an adsorber 2 filled with an adsorbent 3 therein for adsorbing the organic compounds in the waste water by the adsorbent 3 in the adsorber 2, supplying a current between an anode 9 and a cathode 8 in water including an electrolyte in an electrolyzer 6 for electrolyzing the water including an electrolyte, and supplying an electrolyte resulting from electrolysis in the electrolyzer 6 to the adsorbent 3 in the adsorber 2 for contacting the electrolyte with the adsorbent 3, so that the organic compounds adsorbed by the adsorbent 3 are desorbed or decomposed.
Abstract:
A food and surface sanitizing apparatus has a compact corona discharge type ozone generator, having a permanently sealed small diameter, concentric anode, dielectric and cathode set which does not require dry air feed and which requires no maintenance. A dedicated cooling apparatus permits consistent ozone output over extended time of use. The apparatus is encapsulated in a housing along with an apparatus for dissolving a portion of the ozone in the stream of water passing through an arrangement of tubing. A sensor recognizes the presence of oxidizer in the water stream and adjusts the output of the ozone generator to maintain a predetermined level of dissolved ozone. A water flow quantifier enumerates the total volume of water processed.
Abstract:
In the field of fluid treatment, there is a need for a more flexible electrocoagulation unit and a fluid treatment apparatus that is readily configurable to deal efficiently with differently contaminated fluids. An electrocoagulation unit (210), for removing contaminants from a fluid, comprises an electrode chamber, which in use has a top and a bottom. The chamber also has a fluid inlet (14) at or towards its bottom, and is in fluid communication with at least one discharge conduit towards its top to direct fluid from the chamber towards a fluid outlet. The electrocoagulation unit also comprises an electrode module (234) which is removable through the top of the electrode chamber and includes at least one support body that supports a plurality of electrodes (38, 42). The electrode chamber and the electrode module co-operate with one another to restrict the flow of contaminated fluid to regions within the electrode chamber adjacent to active surfaces of the electrodes. A fluid treatment apparatus, for removing contaminants from a fluid, comprises at least one electrocoagulation unit as described above and a separation unit. The electrocoagulation unit and the separation unit are fluidly connected in series.
