Carbon Filtration System How & Why?
Filtration is a key part of most water treatment systems, and selecting the right system can be a delicate matter. Media filtration is quite frequently used by municipalities for drinking water treatment. One particular filtration media that is used is anthracite carbon media. Activated carbon filters are best at removing chlorine and bad tastes or odors but may be certified to remove other contaminants. Activated carbon is a porous form of carbon that can be manufactured from a variety of carbonaceous raw materials. The principal commercial products are made from coconut shells, coal, peat, or wood. The activation process involves treating the raw material with steam or chemicals, thereby developing a pore structure. How does it work? The atoms of carbon, comprising the large internal surface area of activated carbon, present attractive forces outward from the surface. These forces, known as Van der Waals forces, attract the molecules of the surrounding gas or liquid. The combinatio
