INORGANIC SILICA [4 records]

Record 1 2014-04-02

English

Subject field(s)
  • Chemistry
  • Water Treatment (Water Supply)
CONT

Inorganic polymers(activated silica) and natural polymers(starches, alginate) were the first to be used. But the appearance of the widely varying synthetic polymers has changed flocculation results considerably.

French

Domaine(s)
  • Chimie
  • Traitement des eaux
CONT

Des polymères minéraux (silice activée) et des polymères naturels (amidon, alginate) ont d'abord été utilisés. Mais l'apparition de polymères de synthèse très diversifiés a fait évoluer considérablement les performances de la floculation.

Spanish

Campo(s) temático(s)
  • Química
  • Tratamiento del agua
DEF

Polímero sin átomos de carbono en la cadena principal.

OBS

Ejemplos: polidiclorofosfazeno, polidimetilsiloxano. En los polímeros inorgánicos pueden estar presentes cadenas laterales de grupos orgánicos; en este caso, a veces se puede hacer referencia a los polímeros como "semiorgánicos".

English

Subject field(s)
  • Water Treatment (Water Supply)
  • Wastewater Treatment
  • Electrochemistry
DEF

Raw or pretreated water used to feed the water purification system for further treatment or polishing.

CONT

Ultrapure water is produced by treating feedwater to reduce the concentration of impurities such as organic and inorganic species, suspended particles, live bacteria, silica and dissolved gases to the parts-per-million(ppm) and parts-per-billion(ppb) range.

OBS

feedwater: term officially approved by the Lexicon Project Committee (New Brunswick).

Key term(s)
  • feed-water

French

Domaine(s)
  • Traitement des eaux
  • Traitement des eaux usées
  • Électrochimie
DEF

Eau qui alimente le système de purification et deviendra eau de procédé après traitement.

CONT

Les techniques d'électrodialyse permettent de récupérer de 70% à 80% de l'eau d'alimentation sous forme d'eau déminéralisée.

OBS

Eau d'appoint est un terme à rejeter. Il signifie : eau venant remplacer de l'eau perdue.

OBS

eau d'alimentation : terme uniformisé par le Comité du projet de lexiques (Nouveau-Brunswick).
