  • Patent number: 7713410
    Abstract: In a waste water treatment apparatus and/or method, waste water containing aminoethanol and dimethyl sulfoxide is introduced into a first denitrification tank within a first waste water treatment apparatus. Malodorous gas generated in the first waste water treatment apparatus is decomposed and treated in a second waste water treatment apparatus where another waste water is treated as another system. The second waste water treatment apparatus has a second nitrification tank including a semi-anaerobic section. The malodorous gas is introduced from the first waste water treatment apparatus into a scrubber. The malodorous gas is treated by sludge which is circulated between the second nitrification tank and the scrubber.

  • Patent number: 7662288
    Abstract: In a water treatment system, micro-nano bubbles are used in a production device and a detoxification device as one example of the upstream treatment devices which perform specified treatment with use of water. The micro-nano bubbles are used again in the waste water treatment by a waste water pretreatment device and a waste water treatment device in the subsequent step. Since the micro-nano bubbles are reused, the efficiency of the micro-nano bubbles can be enhanced. Moreover, according to the waste water pretreatment device, treatment water is pretreated with the microorganisms activated by micro-nano bubbles and propagating in a polyvinylidene chloride filler material and then it is introduced into the waste water treatment device in the subsequent step. Thereby it is possible to reduce the waste water treatment load in the waste water treatment device in the subsequent step.

  • Patent number: 7641798
    Abstract: A waster water treatment apparatus has micro-nano bubbles generation tanks, mixing tanks, a submerged membrane tank, a contact oxidation tank, and an activated charcoal adsorption device. In the micro-nano bubbles generation tanks, micro-nano bubbles are added to the waste water. In the mixing tanks, the waste water containing micro-nano bubbles is mixed with sludge containing microorganisms. In the contact oxidation tank, the waste water containing organofluoric compounds is microbially treated by the micro-nano bubbles added to the waste water. The micro-nano bubbles activate microorganisms in the waste water. Thereby organofluoric compounds are microbially decomposed with effect.

  • Patent number: 7632400
    Abstract: A water treatment equipment has a raw water tank as a mixing section, a micronanobubble generation tank, a floatation tank, and a treated water tank. Waste water as treatment water is introduced into the raw water tank and mixed with the water containing micronanobubbles produced by the micronanobubble generation tank. Thereafter, the waste water, as treatment water, is introduced into a lower mixing section of the floatation tank from the raw tank by a raw water tank pump. Also, treatment water containing fine bubbles is introduced into the lower mixing section from a pressure tank. Therefore, the micronanobubbles is mixed with the fine bubbles in the lower mixing section of the floatation tank, thereby almost all the suspended matter in the treatment water is surfaced. Thus, the water treatment equipment enhances separatability of suspended matter.

  • Patent number: 7628912
    Abstract: The application device for liquid containing micro-nano bubbles generates micro-nano bubbles in a wide size distribution with use of a submerged pump-type micro-nano bubble generator and a spiral flow-type micro-nano bubble generator. A micro-nano bubble generating aid metering pump is controlled by a bubble level meter and a level controller, so that the supply amount of a micro-nano bubble generating aid is controlled in response to the level of bubbles from a fluid level. The supply amount of a micro-nano bubble generating aid is also controlled by a turbidimeter and a controller in response to the turbidity of the liquid in a micro-nano bubble generation tank, while the amount of air supplied to the submerged pump-type micro-nano bubble generator is controlled in response to the turbidity of the liquid. Therefore, the device can produce a large amount of various micro-nano bubbles in a wide size distribution more economically.

  • Publication number: 20090266763
    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 (11) 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.

  • Patent number: 7575684
    Abstract: In waste water treatment apparatus and method, a mineral mixing tank receives biologically treated water, sludge which is generated by biological treatment, and mineral sludge which contains calcium and so on from a settling tank. A mineral pump returns the sludge and the treated water from the mineral mixing tank to a raw water tank. An air-lift pump circulates treatment water between a reaeration tank having a semi-anaerobic section and a denitrification tank. In circulation of the treatment water between the reaeration tank and the denitrification tank, the semi-anaerobic section alleviates the change of environment for microorganisms and thereby realizes the environment easy to propagate for the microorganisms. The air-lift pump allows the agitation with low energy consumption even when the microorganisms are cultured up to a high concentration thereof.

  • Publication number: 20090145827
    Abstract: A first treatment tank (1) to a fourth treatment tank are installed prior to ultrapure water production apparatus (5), dilute wastewater recovering apparatus (34), general service water recovering apparatus and wastewater treatment apparatus. The treatment tanks (1, 2, . . . ) each have a micro-nano bubble generation tank (6, 23, . . . ) and an anaerobic measuring tank (7, 24, . . . ). Accordingly, microbes within the respective anaerobic measuring tanks (7, 24, . . . ) are activated by micro-nano bubbles generated in each micro-nano bubble generation tank (6, 23, . . . ) to thereby enhance the treatment efficiency of low-concentration organic matter. Further, when the value measured by dissolved oxygen meter (13, 30, . . . ) or oxidation-reduction potentiometer (14, 31, . . . ) of each anaerobic measuring tank (7, 24, . . . ) exceeds an individually determined given range, the rotational speed of a circulating pump (9, 26, . . . ) is controlled to thereby decrease the generation of micro-nano bubbles.

  • Publication number: 20080276112
    Abstract: A memory interface circuit is connectable to a DDR-SDRAM which outputs read data in synchronization with a data strobe signal together with the data strobe signal. A clock generator generates internal clock signals and memory clock signals supplied to the DDR-SDRAM. The memory interface circuit determines a delay of arrival of the data strobe signal relative to the corresponding internal clock signal by using a data strobe signal inputted in a read cycle with respect to the DDR-SDRAM, samples the arrived read data, based on a signal obtained by shifting the phase of the arrived data strobe signal, and synchronizes the sampled read data to the corresponding internal clock signal on the basis of the result of determination of the arrival delay.

  • Publication number: 20080189847
    Abstract: In the upper part and the lower part of a micro-nano bubble generation section 34 in a micro-nano bubble bathtub 1, two kinds of micro-nano bubbles different in a size distribution are generated by first and second micro-nano bubble generators (submerged pump-type micro-nano bubble generator 2 and spiral flow-type micro-nano bubble generator 10) of two kinds, so that bathtub water containing micro-nano bubbles in a wide size distribution can be produced in a large amount. Some of the water containing micro-nano bubbles generated in the lower part is thrown into the first micro-nano bubble generator (spiral flow-type micro-nano bubble generator 10) in the upper part, so that the spiral flow-type micro-nano bubble generator 10 can generate micro-nano bubbles in a smaller size. Therefore, in this bathtub, micro-nano bubbles abundant in size and large in amount can be produced economically.
