DIAPHRAGME TOILE METALLIQUE [3 records]

Record 1 1987-11-05

English

Subject field(s)
  • Electrolysis (Electrokinetics)
  • Electrochemistry
  • Chemical Engineering
CONT

Most of the chlorine produced in the world is manufactured by electrolysis of sodium chloride brine. Two processes are in common use: the mercury cell process and the diaphragm cell process.

CONT

In production of chlorine by the diaphragm cell process, salt is dissolved in water and stored as a saturated solution. ... The purified saturated brine is then fed to the cell which typically is a rectangular box. It uses vertical anodes ... The cathode is perforated metal which supports the asbestos diaphragm. ... The diaphragm serves to separate the anolyte (the feed brine) from the catholyte (brine containing caustic soda). Chlorine is evolved at the anode.

Chlore. Fabrication industrielle.(...) on a recours à deux procédés : le procédé au diaphragme(...) et le procédé à cathode de mercure. Procédé au diaphragme. Une couche d’amiante(...), montée sur une toile métallique ou une tôle perforée formant cathode, isole celle-ci de l'anode en s’opposant à la diffusion de la soude vers cette dernière : ce diaphragme, perméable aux ions, augmente cependant la résistance du bain(...)

A filter used in water treatment, in which a built-up layer of diatomaceous earth serves as the filtering medium.

OBS

diatomaceous earth: A fine, siliceous earth consisting mainly of the skeletal remains of diatoms (unicellular organisms).

French

Domaine(s)
  • Équipement et outillage (Alimentation en eau)
  • Traitement des eaux
DEF

[...] filtre [qui] consiste en un support ou diaphragme(toile ou fil métallique) qui soutient une couche de diatomées à travers laquelle passe l'eau.

OBS

Les diatomées sont des carapaces siliceuses fossilisées d’origine marine, très fines [...] et ayant un certain pouvoir adsorbant. En présence d’eaux chargées de colloïdes, elles permettent une meilleure clarification que celle obtenue avec la cellulose.
