This study investigates the influence of widely ranged soil cadmium and nickel content on the biomass quantity and quality produced by Arundo donax L. (giant reed). The aim was to determine whether giant reed is hypertolerant to these heavy metals and therefore could exploit polluted sites, which co

Bioremediation is being increasingly seen as an affective, environmentally friendly treatment for contaminated shorelines from marine oil spills. Oil bioremediation is limited by the availability of nitrogen and phosphorous, which are needed by the bacteria and are not present in sufficient amounts

Precipitation of lead and bromide, followed by careful crystallization, is usually discussed when the production or synthesis of lead bromide is involved. However, there are numerous issues, especially concerning the precipitation of lead bromide hydroxide (Pb(OH)Br) and its derivatives in the neutr

This paper deals with the development and application of two methods for the de-contamination of waste and underground water polluted by a variety of hazardous halogenated organic substances, namely polychlorinated biphenyls, chlorophenols, perchlorates and especially their decomposition products di

The evaluation of a chemical (sodium dodecyl sulfate, SDS) and a natural (humic acid) surfactant, in order to enhance the electrokinetic removal of cadmium from contaminated soil has been investigated in this study. SDS was used either for soil washing as well as purging solution. When SDS was used

The aim of the study was to evaluate polycyclic aromatic hydrocarbons (PAHs) removal during co-fermentation of sewage sludge and organic fraction of municipal solid waste under nitrate and sulphate reducing conditions. Samples were incubated at 37°C for 20 d. Two series of experiments were running s

The AQUASOL-Enhanced Zero Discharge Seawater Desalination using Hybrid Solar Technology (EVK1CT2001-00102) project is one more attempt at using solar energy for water desalination, improving the economics and the environmental performance of a MED desalination plant. Within the project, an advanced

An electroenzymatic method is developed to degrade 2-chlorobiphenyl (2-CB) with horseradish peroxidase (HRP) immobilized glassy carbon electrode as the working electrode. Cyclic voltametric studies were carried out to understand the redox reactions involved. An applied potential of –0.5 V was found

Wastewater in Jordan can be characterized as very strong with high salinity and insignificant heavy metals and toxic organic compounds. For the past two decades Jordan has relied on waste stabilization ponds (WSP) to treat wastewater for reuse in agriculture. This has exacerbated the salinity proble

The purpose of the present study was to estimate Cr(VI) removal through biological mechanisms in biofilm reactors operated in SBR operating mode with recirculation using different filter media types. The choice of the support material is of great importance since chromate reduction is followed by th
