摘要： A spent caustic treatment process addresses the shortcomings with traditional Wet Air Oxidation Systems. The process can treat either refinery or sulphidic spent caustic streams with CODs of up to 50,000 mg/L. The process uses >90% oxygen as an oxidising agent. A horizontal, tubular reactor is operated at pressures between 100 and 170 Bar (ideally 145-165 Bar). The reactor has an operating temperature of between 120° C. and 320° C., ideally 280° C. to 300° C. A closed heat transfer medium circulation loop is utilised for heat recovery from the reactor effluent stream to the spent caustic feed stream. The invention allows for a COD reduction of 75 to 99.9%.

摘要： The invention relates to a process for treating a waste lye of a lye scrub using an oxidation reactor (100), the waste lye and oxygen or an oxygen-containing gas mixture being introduced into the oxidation reactor (100) and steam being introduced into the oxidation reactor (100). It is provided that the steam is at least partially introduced by means of a steam feeding device (10), which has a cylindrical section (11) with a centre axis (12) and a wall (13), the centre axis (12) being aligned perpendicularly, a number of groups of openings (14) being formed in the wall, each of the groups comprising a number of the openings (14), and the number of openings (14) of each of the groups being arranged in one or more planes (15) that is or are in each case aligned perpendicularly to the centre axis (12). A corresponding installation and also a corresponding oxidation reactor (100) are likewise the subject of the present invention.

摘要： A gas-dissolving device can dissolve a gas in a liquid at a high concentration, and can maintain the concentration of a dissolved gas even in a state in which a circulation operation has been stopped. The gas-dissolving device of the present invention comprises: a dissolving tank for receiving a liquid and a gas from each of a circulation pump and a gas source, and discharging a liquid/gas mixture with an increased dissolved gas concentration in the liquid; and a pressurization dissolving part which is fluidically connected to the dissolving tank, and which has a wound coil portion or a plurality of bent portions to further increase the concentration of the dissolved gas, and thus discharge a high-concentration-gas solution. The dissolving tank includes: a plurality of dispersing trays, which are each formed in a shape of having an inclined surface extended in the outer downward direction; and a plurality of water-collecting trays, which are each formed in a shape of having an inclined surface extended in the inner downward direction and each have a through-hole formed at the lower end thereof, wherein the plurality of dispersing trays and the plurality of water-collecting trays are alternately arranged in the vertical direction.

摘要： Various embodiments relate to denitrification of water using bacteria. A method of denitrification of water includes deoxygenated water including a water-soluble form of nitrogen. The method includes exposing the deoxygenated water to denitrifying bacteria to convert the water-soluble form of nitrogen in the water to nitrogen gas that is removed and to form a denitrified water. The method also includes reoxygenating the denitrified water. Denitrifying bacterial substrates and methods of making the same are also provided.

摘要： A cost-effective system and method dissolves gas, such as oxygen, into water in a manner that prevents gas bubble carry over by using a bubble capture system (BCS). The system and method further eliminates or minimizes turbulence at the suction and discharge of a pump using an energy dissipation header (EDH). The BCS can create a top-down flow that permits bubbles to rise faster than the velocity of the downward flow of water. The EDH can use a pipe design, such as a slotted pipe design, that permits a maximum system water flow. The technology can be applied to water bodies to mitigate eutrophication and may also be applicable in other fields, such as wastewater lift stations, fish farms, oil and gas industry, tidal applications with low flushing rates, and winter under ice oxygenation to prevent fish kills.

摘要： Methods of treating contaminated groundwater having recalcitrant organic contaminants are disclosed. The methods include pretreating the contaminated groundwater to remove iron, introducing a persulfate to the contaminated groundwater, and exposing the contaminated groundwater to irradiation. The methods may also include extracting the contaminated groundwater from a feed stream. The methods may also include preparing the persulfate with high purity water. Systems for treating contaminated groundwater having recalcitrant organic contaminants are also disclosed. The systems include a pretreatment subsystem, a source of persulfate, and an irradiation source.

摘要： A water treatment device and methods of treating water such as cooling tower water, agricultural water, water used in the production of oil and/or gas, swimming pool water, and hot tub or spa water, are described. The water treatment device utilizes ultraviolet radiation, a magnetic field, and ozone fortified air to treat the water, typically resulting in reduced microbial contamination and reduced alkalinity in cooling tower water. Cooling tower water may consequently be run at higher cycles of concentration while reducing or eliminating deposition of minerals on cooling tower components. Swimming pool water and hot tub water treated with the water treatment device typically requires less chlorine, and chlorine levels are typically more stable than without the device.
