摘要:
Disclosed is a dissolved air floatation device which includes a cyclonic flotation separation tank, arranges a return pipe for treated water and a return pipe for floating scum concentrically with respect to the center pipe of a swirling flow within the floatation separation tank, forms a descending water flow along with an ascending water flow within the flotation separation tank, thereby being capable of simultaneously separating settled suspended material and floating suspended material in raw water at an improved efficiency.
摘要:
A separation system is presented that partitions a slurry containing a plurality of particles that are influenced by a fluidization flow (which comprises teeter water and gas bubbles) and a fluidized bed. The separation system comprises a separation tank, a slurry feed distributor, a fluidization flow manifold and a gas introduction system. All of these components are arranged to create the fluidized bed in the separation tank by introducing the slurry through the slurry feed distributor and allowing the slurry to interact with the fluidization flow that enters the separation tank from the fluidization flow manifold. The gas introduction system is configured to optimize the gas bubble size distribution in the fluidization flow. The gas introduction system comprises a gas introduction conduit and a bypass conduit. The gas introduction system can be adjusted by modulating the flow of teeter water through the gas introduction conduit.

摘要:
A liquid treatment system using gas flotation to separate suspended matter from liquid influent, including a flotation tank into which the liquid influent is fed through an inlet, an outlet conduit through which treated effluent is fed from the flotation tank, a separation conduit for feeding liquid to a bubble release point, means for pressurising the liquid in the separation conduit and dissolving gas in the pressurised liquid, wherein an energy recovery device is used for reducing pressure of the liquid before the bubble release point such that gas bubbles are released into the flotation tank for floating said suspended matter to a surface of the liquid in the tank, and wherein the energy recovery device supplies energy obtained through said pressure reduction of the liquid.
摘要:
The present invention relates to a high-rate sedimentation tank and a water treatment apparatus including the same, and a high-rate sedimentation tank capable of quickly removing a floc formed by flocculating foreign materials, etc., included in raw water as sludge and a water treatment apparatus including the same. According to the exemplary embodiments of the present invention, the sedimentation tank may quickly deposit the sludge using a circular orifice pipe to increase water treatment efficiency such as shortening water treatment time and may deposit the sludge without power to decrease maintenance and management costs of the water treatment apparatus. Further, according to the exemplary embodiment of the present invention, the sedimentation tank may minimize a site area while quickly depositing the sludge, and thus may be easily installed even in a narrow area and may decrease costs required for the installation of the water treatment apparatus.
