Title: Improvements relating to separation of charged molecules
Inventor: MARGOLIS JOEL
IPC: B01D61/42
Filed: 1988-04-05
Abstract: Apparatus for the migration of at least one solute macro species in an electric field from a first solvent stream to a second solvent stream in relatively large quantities. The apparatus comprising a pair of electrodes positioned within a housing, each electrode being positioned adjacent one of a pair of opposed ends of the housing and each being surrounded by means to direct a flow of a suitable buffer past the electrode, the housing having first inlet means through which the first solvent stream is introduced into the housing and outlet means therefor, second inlets means through which the second solvent stream is introduced into the housing and outlet means therefor, and a plurality of electrophoretic membranes extending in substantially parallel spaced apart, array. The membranes are positioned intermediate the electrode and serve to separate the first solvent stream from the second solvent stream. The first solvent stream is moved through the housing in pulsitile or stepwise fashion and the voltage across the electrodes is periodically stopped or reversed. Adjacent membranes are separated by pairs of woven screens the meshes of which are so selected that they will not nest together. The housing may be connected to containers for the various solutions and the source of electric potential by a single bundle of tubes and wires forming an umbilicus. The housing is thereby rendered capable of being moved independently of such containers.

Abstract: The power supply device according to the invention contains an adjustable autotransformer (3) and a train transformer (6) to which are connected a thyristor converter (7), an inductor (8) and a drive motor (9). The driving switch (11) is connected to an information-processing block (12) whose second and third inputs are connected to the train transformer (6) and the drive motor (9). One output from the information-processing block (12) leads to a delay angle determination block (13) for determining the delay angle on the front and rear faces of the voltage. The delay angle determination block (13) is connected to a delay angle change-preset block (14) whose outputs are supplied to a buffer distributor (15) and to a delay angle delimiter (16). The two outputs of the latter are supplied to the preset block (14) and to the buffer distributor (15), to whose third input a second output of the information processing block (12) is supplied. The outputs of the buffer distributor (15) are connected to the position selector (5) and to the control unit (17) for the thyristors of the converter (7) and of a forced-commutation block (10). The power supply device according to the invention facilitates control at high power factor levels. The cos  phi  can be controlled continuously at a value near unity on the basis of the first harmonic of the current; in addition, the arrangement allows a flat phase control, resulting in favourable values of the curvature coefficient.   <IMAGE>

Les dérivés de lignine sont dispersés dans les eaux d'exhaure, et un coagulant est ajouté, ce qui porte le pH jusqu'à environ 4,5 - 8,5 et provoque la formation d'un floculat. On ajoute ensuite la composition alcaline pour porter le pH jusqu'à environ 9 à 10, ce qui provoque la formation de quantités supplémentaires de floculat. En variante, on effectue l'oxydation par air de manière à réduire le pH jusqu'à environ 8,1 - 8,6. En variante également, on peut ajouter un sel ferrique ou ferreux. Les floculats comprennent des colloïdes métal - lignine, des hydroxydes de métaux et des sels métalliques. Les floculats coagulent pour former une boue. En variante enfin, on peut ajouter des cendres volantes ou de la terre de diatomée pour augmenter la densité et la stabilité de la boue. La boue ainsi formée contient les métaux, et est séparée des eaux traitées par filtrage.
