Efficient particle separation on the way to meet stringent regulatory criteria signify one of many greatest demanding situations dealing with the method operators this present day. rising environmental difficulties corresponding to weather swap, inhabitants progress and usual source depletion make it extra compelling to adopt study into replacement section separation ideas and optimization of present ones. assembly this problem calls for cutting edge, innovative and built-in method within the layout and optimization of varied unit techniques in superb particle separation.

Flocculation is usual as a good part separation procedure throughout many method industries akin to water and wastewater therapy and in minerals processing. during this paintings, a brand new pre-treatment strategy used to be built utilizing a patented bench scale reactor unit as a technical evidence of idea. additionally, the booklet presents a worthy perception into the hydrodynamics and fluid-particle interactions in the agglomeration units.

The rather excessive solids content material of the strong pellets (approximately 30 percent) and intensely low residual turbidity of the post-sedimentation supernatant (7 NTU) basically reveal the opportunity of this system. as well as considerably bettering the following solid-liquid separation potency, this examine additionally confirmed that the effluent may be recycled again into the sewer community or applied for non-portable reuse. The findings received from this study can be tremendous precious within the scaling up and optimization of the reactor system.

By Horst Briehl

ISBN-10: 3835102230

ISBN-13: 9783835102231

Dieses Lehrbuch wendet sich in erster Linie an Studierende der Ingenieurwissenschaften, die während ihrer Ausbildung und im späteren Berufsleben mit Problemen der Auswahl und des Einsatzes des jeweils richtigen Werkstoffs konfrontiert werden. Chemische Reaktionen spielen bereits bei der Herstellung von Werkstoffen eine bedeutende Rolle. Auch viele weitere Verarbeitungsschritte wie z.B. Raffinations-, Veredlungs-, Formgebungs- und Verfestigungsverfahren sowie Methoden der Fertigung von Verbundwerkstoffen bzw. die Fixierung von Schichten auf Substratmaterialien beruhen meist auf chemischen Vorgängen. Alterun- erscheinungen und Korrosionsprozesse an Werkstoffen sind durch die Chemie erklärbar; ebenso basieren zahlreiche Recyclingverfahren für ausgediente Werkstoffe auf chemischen Reaktionen. Warum nun „Chemie der Werkstoffe'? Beim Studium von gängigen Chemielehrbüchern, ist häufig festzustellen, dass in diesen meist wissenschaftlich orientierten Büchern Werkstoffe und deren te- nische Anwendungen ein wenig vernachlässigt werden. Andererseits erfolgt in Fachbüchern über Werkstoffe bisweilen eine nur recht stiefmütterliche Behandlung der chemischen Reaktionen von Werkstoffen. Ferner werden in den reinen Werkstoffkundebüchern oft nur ganz bestimmte Werkstoffgruppen (z.B. Kunststoffe, Keramiken oder Metalle) separat behandelt. Im vorliegenden Buch werden nun die wesentlichen Grundzüge der Chemie von metallischen, nichtmetallisch-anorganischen und organischen Werkstoffen dargestellt, und zugleich wird auf c- rakteristische Eigenschaften und daraus resultierende Anwendungen dieser Werkstoffe eingegangen. Bestimmte physikalische Größen, die besonders kennzeichnend für einen Werkstoff sind, sind in der Regel herausgestellt; allerdings ist dieses Buch keine werkstoffkundliche Datensammlung, da im Vordergrund immer die Chemie des Werkstoffs steht. Dies führt insbesondere bei der Einteilung und Behandlung der metallischen Werkstoffe zu einer starken Orientierung am Periodensystem.
