Fresh water resources are under tremendous stress throughout the globe. Many areas all along the developing or even developed nations indicated, the fresh waters are greatly contaminated by the discharge of untreated sewage/industrial effluents and even variety of toxins entering naturally. Environmental regulations and public health concerns stated that wastewaters collected from municipalitie...

Abstract The significant problem is the treatment of landfill leachate characterized by high chemical oxygen demand (COD) and total organic carbon (TOC) presence biodegradation inhibitors such as heavy metals oily substances. For case (pH 7.9, color 1550 mg Pt/L, COD 1880 O 2 /L, TOC 620 mg/L, nitrogen (TN) 220 phosphorus (TP) 6 mg/L metals), effect elevated pressure temperature on decrease val...

The use of ferrate has been demonstrated as a highly efficient technique for the removal pollutants in water and wastewater treatment. While most published work about investigated treatment performance by alone, new applications expand to synergistic application with other techniques such membrane separation, sulphur-based chemical use, UV radiation, ozonation, acidification, additives. This pa...

Potassium ferrate, an analog of orthophosphate and a potent oxidizing agent, was found to irreversibly inactivate porcine muscle adenylate kinase. Inhibition was prevented by competitive inhibitors or substrates, indicating that the action of ferrate was site-specific. Inactivation was accompanied by the loss of Cys-25 and Tyr-95. P1,P5-di(adenosine 5')-pentaphosphate (10(-7) M), a powerful com...

The goal of this experiment is to evaluate the effectiveness of different leachate pre-treatment options in terms of COD and ammonia removal. This research focused on the evaluation of physical-chemical methods for pre-treatment of leachate that would be effective and rapid in order to satisfy the requirements of the sewer discharge by-laws. The four pre-treatment options evaluated were: air st...
