Soil Washing for Remediation of Non Volatile Hydrocarbon Polluted Soils
This paper illustrates the possibilities of applying what is essentially a physical soil-washing technique for treatment of soil contaminated by semi-volatile hydrocarbons in order to reduce the level of pollution to that permitted by Italian regulations. The ground around a factory producing lubricating-oil additives consists of silty-sandy soils, which have long been contaminated by heavy hyd...
متن کاملA model with mass transport limitations for pump and treat remediation of soils polluted with NAPL.
A model is presented for the description of the pump and treat (or flushing) remediation of the saturated zone with non-aqueous phase liquid (NAPL) present as droplets. Sensitivity analysis shows that the most important variables are the NAPL droplet size and the distance through which the dissolved organic compound must diffuse to reach the advecting aqueous phase. The time needed to achieve c...
متن کاملNew perspectives for the application of diatomaceous earth to the remediation of polluted waters and soils
Research effort dealing with the remediation of leaching waters polluted to prevent further damage of surface and ground water reserves are needed. For this purpose, diatomaceous earth, an inexpensive, available and no pollutant material, has been tested for retention of persistent pollutants, such as heavy metals (cadmium) and pesticides (atrazina and chlorpirifos). It has been used as undergr...
متن کاملThe potential of willow for remediation of heavy metal polluted calcareous urban soils.
Growth performance and heavy metal uptake by willow (Salix viminalis) from strongly and moderately polluted calcareous soils were investigated in field and growth chamber trials to assess the suitability of willow for phytoremediation. Field uptakes were 2-10 times higher than growth chamber uptakes. Despite high concentrations of cadmium (>/=80 mg/kg) and zinc (>/=3000 mg/kg) in leaves of will...
متن کاملBioremediation of Phenanthrene Polluted Soils
The best metabolic conditions for the biodegradation of hydrocarbons by a selected microbial consortium from a natural soil were investigated in order to improve the efficiency of bioremediation processes for cleaning of polluted waters and soils. Phenanthrene is one of the most recalcitrant pollutants to microbial decomposition and most difficult to remove. A microbial consortium was selected ...
