Norit offers over 150 different varieties of activated carbon to ensure the precise fit for your application. This precise fit translates into best performance whether it's meeting critical product specifications, using the least amount of carbon to accomplish your task, or getting longer treatment cycles and fewer change outs. While activated carbon may look the same to the naked eye, pore size and structure make a huge difference in how well impurities are adsorbed. This is why Norit has taken the time to test thousands of combinations of raw materials, activation methods, activity levels, and other factors.
