Abstract: A water purification system performs a water purification process through physical sterilization, and at least includes a compression device and a decompression device. Water is converted into a high-pressure liquid through the compression device, and then is converted into a high-speed fluid by controlling the cross-sectional area of a spout of the decompression device, thus generating physical effects such as pressure drop and shear stress, so as to damage cell walls of bacteria in the liquid to die-off the bacteria. Therefore, purified water is obtained.

Abstract: Methods and systems for utilizing biological wastewater treatment processes to remove nutrients from wastewater containing reduced sulfide compounds may include treating the wastewater in an anaerobic zone, an anoxic zone, and an aerobic zone. The wastewater is first treated in the anaerobic zone to uptake residual biodegradable organic material using specialized bacteria known as phosphorus accumulating organisms (“PAOs”) and glycogen accumulating organisms (“GAOs”). After treatment in the anaerobic zone, the wastewater is treated in an anoxic zone to convert nitrates to nitrogen gas and sulfur to sulfates. Following treatment in the anoxic zone, the wastewater is treated in the aerobic zone to oxidize ammonia to nitrate and to complete removal of phosphorus. After treatment in the aerobic zone, the wastewater may be treated in other zones, or may be delivered to a liquid-solids treatment stage.

Abstract: Water purification systems utilizing oxidation. By passing water through a chamber of air, the impurities within the water, such as iron, manganese, and/or hydrogen sulfide gas, may be oxidized. The oxidized constituents in the water may then precipitate out and be removed by filter media. Thus, by utilizing oxidation, the impurities most commonly found in a consumer's water are readily removed. Additionally, the water purification systems of the present invention may also elevate the pH, i.e., reduce the hydronium ion concentration, of the water when the water is acidic. By raising the pH of the water, the oxidation of impurities, such as iron and manganese, is more complete and also occurs at a faster rate. Additionally, the corrosivity of the water is also reduced when the pH is elevated.

Furthermore, the system comprises a programmable logic controller, which controls motors, pumps, valves, and environment monitoring instruments.

Abstract: Water (23) that contains micro-nano bubbles generated in a micro-nano bubble generation tank (6) is introduced and treated in a charcoal water tank (ii) which is filled with a charcoal (15) and in which an air diffusing pipe (12) is placed and thereafter introduced and treated in a membrane device (21). Thus, activities of microorganisms propagating in the charcoal (15) are increased by the micro-nano bubbles, markedly increasing ability of decomposing organic matters in the water. Therefore, a clogging phenomenon due to the organic matters can be prevented by reducing organic loads on the membrane device (21). Moreover, a very small amount of alcohols or salts are added as a micro-nano bubble generation aid to the micro-nano bubble generation tank (6), improving an incidence rate of the micro-nano bubbles. The alcohols and salts are easily decomposed by the charcoal water tank (ii) and easily removed by the membrane device (21).

Abstract: A coalescer is used in series with a hydrocyclone to enhance the removal of a dispersed phase from a continuous phase by first using a coalescer that lacks removal of any separated dispersed phase prior to cyclonic action in the hydrocyclone. The dispersed phase may be oil and the continuous phase may be water. The coalescer has no oil outlet and serves to coalesce the droplets or particles of the disperse phase together thereby increasing contaminant size distribution. The hydrocyclone functions as a separator operating at higher removal efficiency. The method and apparatus are useful to clarify produced water from hydrocarbon recovery operations, particularly those on offshore platforms where it is desirable to reduce weight and footprint area but still achieve very low oil concentration in the clarified water—even to levels sufficient for the water to be discharged directly into the environment, e.g. the ocean.
