Anaerobic digestion of olive-mill wastewater (OMW) was carried out in a continuously fed mode bioreactor. The bioreactor was operated at different hydraulic retention times (HRTs), using OMW, either raw or pre-treated with white-rot fungi. Two different kinds of feed were tested in this process, one...

Atrazine, a chlorinated s-triazine group of herbicide is one of the most widely used pesticides in the World. Due to its extensive use, long half-life and various toxic properties, it has very high environmental significance. Up to 22 mg l-1 of atrazine was found in ground water whereas permissible...

At present, chemical processes are widely used to remove phosphorus and organic matter from water or wastewater either as the only advanced treatment method or as a pre-treatment stage to biological treatment, and aluminium salts have been traditionally used as coagulants. In the present study...

The mechanism of Methylene Blue adsorption on biosolid (waste sludge) has been studied through batch experiments. The effects of various experimental parameters, such as pH (3- 11), biosolid dosage (1-10 g l-1), contact time (5-1440 min) and initial dye concentration were investigated. The results...

Pollution of the environment with uranium and associated health effects to human have recently become of major concern, particularly due to the use of depleted uranium in armourbreaking bullets. Indeed, uranium in environmentally significant concentrations is found near to uranium mining and...
