Liqui/Jector

Liqui/Jectors : Un outil clé dans le traitement de l'environnement et de l'eau

Le terme "Liqui/Jector" désigne un type d'équipement spécifique utilisé dans diverses applications de traitement de l'environnement et de l'eau. Essentiellement, un Liqui/Jector est un appareil qui utilise le principe de la **venturi-aspiration** pour entraîner et mélanger efficacement les liquides et les gaz. Ce processus crée un moyen très efficace de transférer, disperser ou éliminer les contaminants d'un flux liquide.

Comment fonctionne un Liqui/Jector ?

Les Liqui/Jectors fonctionnent en créant une zone de basse pression à l'intérieur d'une buse venturi. Cette basse pression aspire le gaz ou le liquide à entraîner, créant un mélange avec le flux liquide principal. Ce mélange traverse ensuite le Liqui/Jector, où le matériau entraîné est soit dispersé, soit éliminé, selon l'application.

Applications des Liqui/Jectors dans le traitement de l'environnement et de l'eau :

Les Liqui/Jectors jouent un rôle essentiel dans plusieurs processus de traitement de l'environnement et de l'eau, notamment :

  • Aération : Améliorer la teneur en oxygène des masses d'eau, améliorant l'efficacité des processus de traitement biologique.
  • Dégazage : Éliminer les gaz dissous, tels que le CO2 ou le sulfure d'hydrogène, de l'eau.
  • Injection de produits chimiques : Introduire précisément des produits chimiques dans les flux d'eau pour la désinfection ou l'ajustement du pH.
  • Absorption de gaz : Transférer les gaz d'un flux liquide à un autre, facilitant l'élimination des composés organiques volatils (COV).
  • Flocculation : Promouvoir l'agrégation des particules dans l'eau, facilitant leur élimination par sédimentation ou filtration.

Coalesceur liquide/gaz par Osmonics, Inc. : Un exemple spécifique

Osmonics, Inc., un fournisseur leader de solutions de traitement de l'eau, propose une gamme de coalesceurs liquide/gaz. Ces coalesceurs utilisent une conception spécialisée avec une structure de maille unique qui sépare efficacement les gouttelettes de liquide d'un flux gazeux. Ce processus élimine le liquide entraîné du gaz, améliorant considérablement sa qualité et réduisant au minimum les problèmes en aval.

Avantages de l'utilisation des coalesceurs liquide/gaz d'Osmonics, Inc. :

  • Élimination efficace des gouttelettes de liquide : La conception du coalesceur garantit une grande efficacité dans l'élimination des gouttelettes de liquide des flux gazeux, ce qui conduit à une meilleure qualité du produit.

Liqui/Jector Exercise

Scenario: A wastewater treatment plant is experiencing issues with excessive dissolved gases in their effluent. These gases are causing odor problems and hindering the effectiveness of downstream treatment processes.

Task: Suggest a potential solution using Liqui/Jectors to address this problem. Explain how the Liqui/Jector would work and the specific benefits it would offer.

Exercise Correction

A Liqui/Jector could be used to implement a degasification process to remove the dissolved gases from the effluent. Here's how it would work:

1. **Venturi suction:** The Liqui/Jector creates a low-pressure zone using a venturi nozzle, drawing in the wastewater containing dissolved gases. 2. **Gas entrainment:** The low pressure causes the dissolved gases to come out of solution and be entrained in the wastewater stream. 3. **Gas separation:** The entrained gases are then released into the atmosphere, effectively removing them from the wastewater.

Benefits:

  • **Odor reduction:** Removing dissolved gases reduces the unpleasant odors associated with wastewater.
  • **Improved downstream treatment:** Eliminating the dissolved gases improves the effectiveness of subsequent treatment stages like biological treatment and filtration.
  • **Reduced maintenance:** Liqui/Jectors are known for their low maintenance requirements and durability.
