Unipak : Un Outil Puissant pour le Traitement de l'Eau et de l'Environnement
Unipak est un terme courant dans l'industrie du traitement de l'eau et de l'environnement, souvent désignant un type spécifique de système de flottation à air dissous (FAD) fabriqué par Unicel, Inc. Ces systèmes jouent un rôle crucial dans l'élimination des solides en suspension et d'autres contaminants des eaux usées et des flux de procédés industriels.
Comprendre la Flottation à Air Dissous (FAD)
La FAD est un procédé très efficace qui utilise l'air dissous pour séparer les solides en suspension de l'eau. Le processus commence par la dissolution de l'air sous pression dans les eaux usées. Cet air pressurisé est ensuite libéré dans un bac de flottation, où il forme de minuscules bulles qui s'attachent aux particules en suspension. La flottabilité de ces bulles d'air entraîne les solides à la surface, formant une couche de boues concentrées qui peuvent être facilement éliminées.

Unipak Exercise:
Task: A municipality is considering installing a Unipak IGF system to treat its wastewater. They need to estimate the potential reduction in sludge volume. Currently, they produce 10,000 kg of sludge per day. Research suggests that IGF systems can reduce sludge volume by 30-50%.
Calculate the potential range of sludge reduction for this municipality using Unipak systems.
Exercice Correction
**Minimum reduction:** 10,000 kg * 30% = 3,000 kg **Maximum reduction:** 10,000 kg * 50% = 5,000 kg Therefore, the potential range of sludge reduction for this municipality using Unipak systems is between 3,000 kg and 5,000 kg per day.

Understanding the Fundamentals
Induced Gas Flotation (IGF) is a highly efficient process used for separating suspended solids from water. It utilizes dissolved air bubbles to create buoyancy, causing the solids to rise to the surface for easy removal.
How IGF Works: A Step-by-Step Guide
- Air Dissolution: Air is compressed and dissolved into the wastewater under pressure.
- Bubble Formation: The pressurized air is released into a flotation tank, where it forms tiny bubbles.
- Attachment & Buoyancy: These bubbles attach to the suspended particles, creating buoyancy.
- Solid Separation: The buoyant particles rise to the surface, forming a layer of sludge.
- Sludge Removal: The concentrated sludge is easily removed from the tank surface.
Advantages of IGF Technology
- High Efficiency: IGF effectively removes a wide range of suspended solids.
- Reduced Sludge Volume: IGF minimizes the volume of sludge produced, lowering disposal costs.
