nutshell activated carbon

nut shell activated carbon
a.huge specific surface area
b.strong abosption
Nut shell activated carbon filter material is selected high-quality coconut shells, walnut shell, apricot, peach shell as raw material. Through series production process and refined, its appearance is black granular. The advantages of nut shell activated carbon filter material are pore structure is developed, high spicific surface, adsorption intensity, low resistance reservoir layer, chemical stability, easy to regenerate. The nut shell activated carbon is suitable for high purity of potable water, industrial water and wastewater treatment chlorine bleaching, from deep purification, deodorant and gold refining etc.
The nut granular activated carbons are refined through carbonization and activation with apricot nutshell as raw material.
