    Dissolved air flotation DAF system for sewage treatment plant in textile dyeing

     

    Our professional DAF is the regeneration of Krofta effective and superficial DAF. The unique effective air dissolution system through the common rail injection & cutting technology, patent ion bubble generation system, realize the energy conversion instantaneously, disintegrate the 3-7μm positive charge bubble cloud to the power of N, change the surface tension of the water molecule and the absorption capacity has been enhanced geometrically. It applies the “shallow pool theory” and “zero speed principle” to distribute the water and discharge the water statically. The solid and liquid is separated vertically, with the HRT for only 2-4minutes. The scruff is discharged instantaneously, with low exhaust suspended substance and turbidityDAF Dissolved Air Flotation System For Sewage Treatment Plant In Textile Dyeing ISO9001

    Structure explaination

    • Integrate flocculation, air flotation, skimmer, sedimentation and mud scraper
    • Influent is pumped into center inlet pipe and evenly distributed to the air flotation pond through distributor
    • The flow rate in distribution pipe is same as its flow out rate but reversely, therefore a "zero speed"
    • The inflow disturbance is minimized and floc is vertically moves under static status.
    • The skimmer moves synchronizely with the main machine, while keep rotating to collects the scum and discharged them out through central mud pipe.
    • The clean water is collected into clean water pipe, which also moves synchronizely with the main machine, The clean water pipe is separated from water distribution pipe by water distribution gear, therefore, no interference.

    Core technology

     

    The high frequency common rail injection strong-solvent cutting patent technology is adopted. The high-speed rotation generates the strong centrifugal force and the micron air integration system makes the dissolved air concentration reach the theoretical maximum value within only three seconds without concentration gradient, which provides guarantee for the manufacturing of large-scale micro bubbles and at the same time, the dynamic factor is reduced substantially and the power consumption cost is subsequently reduced

     

    DAF Dissolved Air Flotation System For Sewage Treatment Plant In Textile Dyeing ISO9001

    The microsecond rapid phase separation device is adopted, which makes the phase of water molecule and air molecule in the dissolved air water separate at high speed in reverse direction in less than one microsecond through special structure, instantaneously gather and form the even micro bubbles carrying charge with the diameter of 3-7μm and therefore make the bubble concentration increase geometrically under the same dissolved air quantity. The integrated charged bubble has changed the surface tension of the water, absorbed with the colored group and part of hydrophilic colloid, which is a revolutionary breakthrough of purification efficiency and meanwhile, the input amount of PAC and PAM is substantially reduced or becomes unnecessary.

    Features

    • The purification pond is shallow, however, its surface has sufficient scum reserve space, which is specially suitable for the treatment of high and dense sewage.
    • It ensure small, or even zero floor space, which could be overhead, assembled or set on the building.
    • It’s set with automatic water level adjustment device, providing wide flow application scope and high scum solid rate
    • It has great rigidity and could be supported by only one “groined” concrete beam. It’s not necessary to build the platform and the civil engineering expense is quite low
    • The rotary joint adopts the high-tech patened technology, which requires no maintenance. The abrasion could be adjusted as well. The long-term operation will not generate the water leakage and belongs to permanent design
    • The key parts and components, such as the bearing, after service life calculation and examined by the industry practice, give extremely low failure tate and low maintenance expenses. The drive and scraping motors are left with sufficient margins to ensure the long-term continuous operation will not be overheated
    • The moving elements are set with multiple protection, which could be reliably operated in the open air for long time
    • It’s set with the lubrication device, which could ensure small maintenance workload and convenient management
