Effect of Sludge Amendment on Remediation of Metal Contaminated Soils
Column-leaching and pilot-scale experiments were conducted to evaluate the use of biosolids (sewage sludges) to control the mobilization of metals from contaminated soils with smelting slags. The pilot-scale experiments using amended soils showed that Cu, Pb and Sb were retained, decreasing their concentrations from 250 g/L, 80 g/L and 6 g/L, respectively in the leachates of contaminated soi...
متن کاملInvestigation of Heavy Metals Accumulation in Plants Growing in Contaminated Soils (Case Study: Qazvin Province, Iran)
Environmental pollution with heavy metals is a global disaster that is related tohuman activities. This study was conducted to determine the extent of heavy metalsaccumulation by plant species in Lia industrial city (Qazvin, Iran) and to investigate theremediative capacity of native plant species grown in the contaminated soils. Soil andindustrial wastewater sampling was done radially along tra...
متن کاملAdsorption and desorption of lead in Iranian acid and alkaline soils amended with sewage sludge-derived biochar
The effective management of sewage sludge materials in an environmentally and economically acceptable way is through the pyrolytic conversion of the sludge to biochar and its use for agricultural purposes. The aims of this work were: (1) to assess the effect of biochar prepared from sewage sludge at two different temperatures (350 ºC and 650 ºC) on the adsorption/desorptio...
متن کاملBioremediation of Soils Contaminated with Gasoline in Bioreactors Containing Earthworms Eisenia Fetida and Mixture of Vermicompost and Raw Activated Sludge
Background and Aims: Nowadays, soil pollution with total petroleum hydrocarbons (TPH) is one of the major environmental issues caused serious problems to human and other living organisms. One of the best and most reliable methods of bioremediation is the use of earthworms known as vermin-remediation. In this study, bioremediation of gasoline-contaminated soil using Eisenia Fetida, the mixture o...
متن کاملImproved compaction of dried tannery wastewater sludge.
We quantitatively studied the advantages of improving the compaction of a powder waste by several techniques, including its pelletization. The goal is increasing the mass storage capacity in a given storage volume, and reducing the permeability of air and moisture, that may trigger exothermic spontaneous reactions in organic waste, particularly as powders. The study is based on dried sludges fr...
