Pollution of marine waters is one of the important issues that has a irreparable effects. Also, in the organic oil pollutants, due to inappropriate effects on the environment and humans health and ability to create cancer, hydro carbons of polycyclic (PAHS) and heavy metals (Ni,Hg,V) have a particular importance. According to the importance of study of the environ mental contaminants in the fou...

most of electricity is generated by thermal power plants in iran. shahid rajaee thermal power plant consists of four 250mw natural gas and fuel oil burning units that is located at 100 km west off tehran. as a result of fuel oil burning in winter time, boilers air heaters are washed and cleaned frequently. the wastewater originating from air heater washing contains suspended solids and differen...

Many microorganisms, especially bacteria, produce biosurfactants when grown on water-immiscible substrates. Biosurfactants are more effective, selective, environmentally friendly, and stable than many synthetic surfactants. Most common biosurfactants are glycolipids in which carbohydrates are attached to a long-chain aliphatic acid, while others, like lipopeptides, lipoproteins, and heteropolys...

The oil of Schinus molle exhibited the maximum fungitoxic activity during the screening of some essential oils against some common storage and animal pathogenic fungi. It showed absolute toxicity against animal pathogens and mild activity against storage fungi. The effective concentrations of the oil varied from 200 to 900 ppm. The toxicity of the oil persisted up to 80 degrees C and 90 days of...

The paper presents basic principles of RF heating and describes its possible applications for oil extraction and soil remediation, based on the experience obtained by several years of work at Consorzio Polo Tecnologico Magona (CPTM). Activities include a complete approach, which goes through the steps of problem formulation, modeling, and experimentation. It is shown that RF heating can represe...
