Liquid Carbon is a fine carbon powder immersed in water so already pre-activated and dust free when you add it. Unlike granular carbon, you don't send the liquid through the carbon, but rather the carbon through the liquid when you use powders (Liquid Carbon). So the Liquid Carbon is added to water or alcohol, leave it there for 24 hours to absorb most impurities, then filter it off, or use a fining agent like alcotec tubo klar to clear off most of it.
