Unipak: A Powerful Tool for Environmental & Water Treatment
Unipak is a common term in the environmental and water treatment industry, often referring to a specific type of induced gas flotation (IGF) system manufactured by Unicel, Inc. These systems play a crucial role in removing suspended solids and other contaminants from wastewater and industrial process streams.
Understanding Induced Gas Flotation (IGF)
IGF is a highly efficient process that utilizes dissolved air to separate suspended solids from water. The process begins by dissolving air under pressure into the wastewater. This pressurized air is then released into a flotation tank, where it forms tiny bubbles that attach to the suspended particles. The buoyancy of these air bubbles carries the solids to the surface, forming a layer of concentrated sludge that can be easily removed.

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.
