Chapter 1: Techniques
Pressure-Activated Activated Carbon (PAC) Technology
The term "Perpac" stands for pressure-activated activated carbon, which is a specialized type of activated carbon filter media. This technology utilizes the principle of adsorption to remove various contaminants from water. Activated carbon, with its vast surface area and porous structure, acts like a sponge, trapping and holding onto impurities.
Here's how Perpac works:
- Pressure Activation: The carbon material is subjected to high pressure and heat during the manufacturing process. This process activates the carbon, creating a vast network of pores and increasing its surface area.
- Filtration: Water is passed through a bed of Perpac filter media. The activated carbon within the bed then attracts and adsorbs a wide range of contaminants, such as organic compounds, taste and odor compounds, chlorine, and heavy metals.
- Clean Water Output: The water exiting the filter bed is free of the adsorbed contaminants, resulting in cleaner and safer water.
Key Features of Perpac:
- High adsorption capacity: The large surface area of Perpac allows it to adsorb a significant amount of contaminants.
- Fast adsorption kinetics: The porous structure of Perpac facilitates rapid adsorption, ensuring efficient contaminant removal.
- Regeneration: Perpac can be regenerated by removing the adsorbed contaminants, extending its lifespan.
- Versatility: Perpac can be used in various applications, including pre-treatment, final polishing, and taste and odor control.
