Patent number: 9845256Abstract: The object is to provide an activated sludge treatment method whereby production of excess sludge is brought substantially to zero; and a method for upgrading existing waste water treatment equipment, employing this method. The method includes a step (1) in which sludge 1 produced in a bioreactor is supplied to a waste water aeration-conditioning tank for activated sludge treatment; a step (2) in which waste water into which the sludge 1 has been mixed is subjected to aeration-conditioning to bring the oxidation-reduction potential to a positive value, and the conditioning treated waste water 1 supplied to the bioreactor; a step (3) in which released water from the bioreactor is considered to release water.Type: GrantFiled: March 7, 2012Date of Patent: December 19, 2017Assignee: JAPAN ALSI CO., LTD.Inventor: Kiyoharu Fujino

Patent number: 7618540Abstract: A flocculant for separating and flocculating oily components and water components is provided so that no sludge is produced when the oily components and the water components contained in the emulsion having a high COD value; and the throughput of the active sludge is not decreased in the secondary treatment of the active sludge. A flocculant for separating and flocculing oily components and water components contained in oil-in-water type or water-in-oil type emulsion, comprises a unit (i), and at least one of units (ii) and (iii) represented by the following formulas: (i) —(C(R1R2)C(R3X))—, (ii) —(C(R4R5)C(R6Y))—, (iii) —(C(R7R8)C(R9Z))—; wherein X is a group having —SO3M, M is hydrogen or a metal element, Y is a group having a quaternary nitrogen atom, Z is an electrophilic group, each R1 to R9 is hydrogen or an alkyl group, and a ratio per molecule of these units (i):(ii):(iii) is (1 to 100):(1 to 100):(1 to 100).Type: GrantFiled: December 15, 2008Date of Patent: November 17, 2009Assignee: Japan ALSI Co., LtdInventor: Kiyoharu Fujino
