Bone char/particles

Choy and McKay (2005) studied the removal of Cu2+ from aqueous phase using bone char in a batch reactor. The volume of the liquid was 1.7 L, the volume of the tank 2 L, and its diameter 0.13 m. A six-bladed flat impeller with a diameter of 0.065 m and a blade height of 0.013 m was used. Absorbent particles of 605- pm diameter were used for the adsorption experiments. 

Technicians working with bone char have found that channelling is minimized by using granules of uniform particle size, and it has been recommended that a sample of char be screened into separate sizes, placing the largest size at the bottom of the laboratory column and the smallest size at the top.17 The carbon should be pre-soaked in the hot liquid to be treated, or in hot water to expel the air from the carbon. Some authorities recommend upward flow others prefer downward flow.
