    摘要： Bei einer Säulenflotationseinrichtung mit zumindest zwei übereinander angeordneten Flotationsstufen (10,20,30), die jeweils durch eine in einen zentralen Flotationskamin (18,28,38) mündende und nach außen abwärts geneigte Strömungsleitkontur (14,24,34) voneinander getrennt sind, wird erfindungsgemäß vorgeschlagen, daß die Strömungsleitkontur (14,24,34) aus einem flexiblen Material besteht.
    Vorzugsweise ist die Strömungsleitkontur in ihrer Neigungsrichtung mechanisch vorgespannt (52,54,56).
    Eine solche Säulenflotationseinrichtung ist sehr wartungsarm und langlebig, weil Verschmutzungen und Anhaftungen an den flexiblen Strömungsleitkonturen durch Bewegungs- bzw. Schwingungsinduzierungen leicht vermieden werden können.

    摘要： A self-cleaning valve for discharge of a pressurized dissolved air flotation aqueous treatment liquid from a high pressure reservoir to a low pressure body of liquid to be treated is provided. The valve includes a discharge head body adapted to be attached to a conduit supplied with pressurized treatment liquid which is provided with a central opening for discharge of a treatment liquid. The opening is controllable by means of a reciprocable cap positioned to reciprocate from a position whereon it restricts flow of liquid through the opening to a position wherein flow in unrestricted. The cap is attached to a reciprocable piston rod attached at its opposite end to a piston that is movable within an enclosed cylinder. The cylinder is provided with a port or opening on each side of said piston into which a source of pressurized air connectable to cause movement of the piston and thus opening and closing of the valve by selectively directing the flow of said pressurized air to either side of the piston. A variable pressure regulating means can be provided to regulate the amount of flow through the valve.

    摘要： A compact dissolved-air-flotation (DAF) clarifier and clarification process utilize three zones for clarification which operate in sequence in a single clarifier. Raw water with suspended solids enters a flocculator at the center of an annular tank where microscopic air bubbles introduced to the inflow float flocked contaminants to form a floating sludge layer. A first clarification, calming and degassing occur here. The water then flows radially outwardly into the tank where further quiet clarification occurs. A third level of clarification occurs in a lower portion of the tank, specifically, in a set of plate-like lamellae, radial and conical, which form inclined channels where a final clarification occurs. The bottom wall of the tank has a set of apertures which allow a gravity flow of clarified water through a layer of pressurized gas to an underlying collection compartment. Level sensors control a valve in the clarified outflow line and an air bleed from the pressurized gas layer to regulate liquid levels in the clarifier. A set of rotating paddles push the sludge layer up a ramp to an inclined discharge conduit. Alternatively, a suction head with a mechanical skimmer sweeps around the tank to draw the sludge through a central hollow pipe to a discharge conduit. An offset drive operating through a belt rotates the sludge removal mechanism and the lamellae.
