Depth Filtration: The Foundation of DFT Classic

DFT Classic, as the name implies, relies on the principle of depth filtration. This technique differs significantly from traditional surface filtration, offering unique advantages for water and environmental treatment.

1.1 Understanding Depth Filtration

Instead of trapping contaminants solely on the filter surface, depth filters utilize a multi-layered, porous media. This structure allows for particles to be captured throughout the filter's depth, resulting in:

• Higher dirt-holding capacity: The filter can hold more contaminants before becoming clogged, extending its service life.
• Enhanced removal efficiency: Smaller particles can be trapped within the media's structure, achieving finer filtration compared to surface filters.
• Reduced pressure drop: The open structure allows for efficient flow rates, minimizing energy consumption.
