Reduction Of Heavy Metals Sludge By Vermicomposting Technique

Two kinds of treatments were used in the current thesis, namely, biological and chemical treatments, to reduce the concentration of four heavy metals (Al, Ni, Zn, and Pb) in the sludge collected from the electronic industry. A biological treatment called vermicomposting technique was employed to exp...
