Abstract: An apparatus and a method for injecting coagulant for water purification are provided to remove colloidal particles, natural organic matters, and disinfection by-products from raw water effectively, by injecting the coagulant into the raw water. A coagulant injection apparatus injects the coagulant to raw water to provide mixed water. The coagulant injection apparatus comprises a first pH meter(171) for metering a pH value of the raw water, a second pH meter(172) for metering a pH vale of the mixed water, and an alkali supplement injector. The alkali supplement injector injects alkali supplement into the raw water so that the pH values from the first and second pH meters are within set ranges, or have set values respectively.

Abstract: An apparatus and a method for purifying water are provided to purify the water reliably and manage the apparatus easily, by improving the evaluation of a coagulating process and reflecting the evaluation in control of a coagulating power. An instant mixing unit(100) mixes coagulant and raw water instantly. A coagulant input and control unit(170) inputs the coagulant into the instant mixing unit and controls the input of the coagulant. A coagulating unit(200) receives mixture water from the instant mixing unit, and performs a coagulation process on the mixture water by a stirring unit. A coagulation measurement and control unit(250) measures the coagulation state and controls the coagulation process within the coagulating unit. The coagulation measurement and control unit includes a light scatter analysis unit(251) and a stir power control unit(252). The light scatter analysis unit measures the growth state of coagulating flocculation through light scatter analysis to evaluate a change tendency of a light scatter analysis value or a light scatter analysis ratio. The stir power control unit controls the stir power so that the light scatter analysis value or the light scatter ratio tends to rise. Further, an adjusting unit is additionally installed in order to adjust an instant mixing strength.

Abstract: A method and an apparatus for condensing and dewatering sludge are provided to improve the efficiency in condensing and dewatering of the sludge, by repeatedly controlling the optimum input amount of organic polymer, and to reuse a discarded water by producing a filtered water in which the polymer does not remain. Sludge is condensed and dewatered by controlling a flow of the sludge, inputting organic polymer into the sludge and stirring the sludge and the organic polymer through quick rotation and filtration, separating solid and a filtered solution from the stirred sludge and organic polymer in a condensing and filtering bath(6), and dewatering the resultant sludge. The inputting of the organic polymer is performed by measuring a flow electric potential value of colloid, which exists within a quick filtered solution generated by the quick rotation and filtration, and repeatedly inputting positive type organic polymer for electrically neutralizing the colloid. The measuring of the flow electric potential value is performed by detecting voltage at both ends of a passage of a streaming potential detector when the quick filtered solution is passed through the passage.
