    Abstract: Mercury-contaminated soil is treated in such a way that the mercury content is reduced from a maximum of 300 mg of mercury per kg of solids to less than 10 mg of mercury per kg of solids. To this end, the contaminated soil is fed in an essentially dry state to a sieve (7), the relatively fine material which has passed through the sieve is fed, together with water, a degreasing agent and a surface-tension-reducing agent, to a shaking table (1) of the Wilfley type, the discharge end of the connecting channel (7a) between sieve (7) and shaking table (1) being below the liquid level. The table (1) is shaken parallel to the ridges (2), the mercury concentrate separated off being discharged in the vicinity of a point essentially diagonally opposite the pulp feed and the treated material being collected in a gutter (4) at the said second side and fed via a pump (11) to at least one dewatering cyclone (12). The overflow material from the cyclone is fed to a thickener (20) in order to separate off suspended sludge particles smaller than 30 to 40 mu m, and said water from which suspended sludge has been removed is recycled to the sieve (7) and/or shaking table (1).

    Abstract: Wettable and non-wettable particles contained in a slurry are separated by flowing the slurry over a rotating disk (12) having a central zone (14), a distinct outside corner (16), and a skirt (15). As the slurry flows in a film over the corner (16), the unwettable particles leave the film and are prevented from rejoining the film by a shelf (19). The process and apparatus are useful in recycling fibre products such as paper and paperboard.

    Abstract: Für die Reinigung und Entwässerung von Feststoff- Wassergemischen bei der Vorbereitung von Baumaterialien und insbesondere bei Recycling-Prozessen wird eine ro buste Waschmuldenkonstruktion aus einem Stahlblech- Waschkasten vorgeschlagen, an den austragsseitig zur verbesserten Entwässerung ein ebenfalls massiver Vibra tionskasten (46) angeschlossen wird, während am Waschkasten (22) selbst mindestens ein Waschpulsator (54) und mindestens ein Förderpulsator (56) in der Gestalt von Hydraulik- oder Pneumatikaggregaten angreifen. Überdies kann die gesamte Einrichtung mit Hilfe eines hydraulischen oder pneumatischen Huborgans (20) um eine Schwenkachse in Austragrichtung hochgeschwenkt, ge gebenenfalls zusätzlich oder alternativ auch in Richtung des Waschwasserüberlaufs hochgeschwenkt werden.

    Abstract: The method described is useful in field flow fractionation techniques for reducing separation times and improving the convenience and accuracy of measuring sizes or molecular weights of particulates. In field flow fractionation, the particulates (particles or macromolecules) are subjected to a force field and a mobile phase while passing throught a flow channel. This filed strength is decreased exponentially as a function of time. Alternatively the flow velocity is increased exponentially as a function of time. The initiation of the change in field strength or flow velocity may be delayed a period of time. If this time delay is made equal to the time constant of the exponential decay, the range of particulate retention time that is linearly related to the logarithm of the particle size or molecular weight is increased. An apparatus for implementing the method is also described and includes a function generator 100 for providing the desired exponential decay and delay time to a speed control 102 controlling a motor 104 of a centrifuge bowl 26.
