767 wood activated carbon for injection is with low impurities, high adsorption, high decolorization, non-poison, so its widely used for pharmaceutical field for the medicine and injection.Wood activated carbon has large pores which are called as mesopores or macropores. Due to the large pore size, they are used for adsorption of large molecular species. It therefore finds application in decolorization process. Wood activated by steam has larger pores and pits, this increases the surface area available for adsorption. Treatment with wood activated carbon helps in BOD (biochemical oxygen demand) reduction which helps in the survival of aquatic flora and fauna, thereby maintaining natural water body sources. Wood activated carbon is used in vapour phase injection systems for waste water treatment.
