Phytoremediation: An economical solution for removal of Heavy Metals

The book gives the information of economical treatment of Industrial effluent carrying heavy metals contamination. Pytoremediation process is best and prudent technique than the other physical, thermal and chemical methodologies. This is a technology to clean the environment from heavy metals contamination & various toxins. The objectives of this study are to treat copper (Cu) and Zinc (Zn) contaminated wastewater by using phytoremediation technology and to determine the appropriate proportion of the both plants i.e. Water Hyacinth & Pistia Stratiotes to be a good accumulator. The results shows that W.H has very high accumulation capacity for Cu & P.S has high accumulation of Zinc. W.H removes maximum amount of Copper & other physiochemical parameters (pH, T.S.S, T.D.S, & C.O.D). W.H removes Cu with the reduction efficiency of 99.40%, whereas Zn removal efficiency is about 84.33%. Therefore, this treatment can be recommended for the small scale treatment facility for removal of heavy metals from various industrial effluents as a non disruptive & low cost treatment system.
