Rate of Copper Ions Removal from Copper Sulfate Solution by Cementation on Steel Turbulence Promoters Using Stirred Tank Reactor

The present study is concerned with the removal rate of Copper ions Cu++ from wastewater by cementation of copper from copper sulfate solution on a horizontal steel sheet placed at the bottom of a square stirred tank reactor and fitted with square steel turbulence promoters. The variables studied were solution concentration, rotation speed, impeller geometry, promoter diameter and distance between promoters. The rate of mass transfer was found to increase with the rotational speed and decreased with the increase of distance between promoters. The data were correlated to develop the relationship Sh α Re x
