Efficiency of Washing Techniques for Removal of Heavy Metals from Industrial Sludge
The effluent treatment plant sludge is one of the major sources of contamination with toxic metals. Since the sludge contains heavy metals, it must be pretreated to reduce the contamination. The heavy metals from the sludge can be reduced/ separated by washing it with a suitable leaching solution. In the present study, the efficiencies of three leaching solutions to remove the contaminants from...

متن کاملUsing Trifolium Alexanderium for Phytoremediation of some heavy metals in tailings dam in Anjir-Tange coal washing plant, Mazandaran, Iran
Phytoremediation is a technology that uses plants for the remediation of the contaminated soils, sediments, tailings, and groundwaters. In this work, the ability of TrifoliumAlexanderium for the phytoremediation of the tailings soil in the Anjir-Tange coal washing plant was investigated. For this purpose, Trifolium sp. was cultivated in three soils consisting of the tailings dam, an agricultura...
متن کاملSimultaneous Removal of Cadmium and Turbidity in Contaminated Soil-washing Water by Electroflotation
The removal of cadmium and turbidity from contaminated soil-washing water was studied by Electroflotation (EF) at the laboratory scale by using sodium lauryl sulfate (SLS) as an anionic surfactant, and calcium hydroxide (Ca(OH)2) as a coagulant. The stoichiometric cadmium to collector (SLS) and coagulant (Ca(OH)2) ratio was 1:4.5. Significant removal of cadmium (100 %, not detected in the resid...
متن کاملBioremediation of heavy metals and petroleum hydrocarbons in diesel contaminated soil with the earthworm: Eudrilus eugeniae
A laboratory study on the bioremediation of diesel contaminated soil with the earthworm Eudrilus eugeniae (Kingberg) was conducted. 5 ml of diesel was contaminated into soils in replicates and inoculated with E. eugeniae for 90 days. Physicochemical parameters, heavy metals and total petroleum hydrocarbons were analyzed using AAS. BTEX in contaminated soil and tissues of earthworms were determi...
