Abstract: Biological decomposition techniques and isolation of environmental pollutions using biosurfactant bacteria are one of the effective methods of environmental protection. Biosurfactants are amphilice compounds were produced from several species of bacteria. They are environmentally friendly, biodegradable, less toxic and non-hazardous. This paper is designed to investigate experimentally removal of oil […]

A Study of Surface Biosurfactants Applications in Oil Degradation



Abstract: Waste polymer recycling has received a great attention due to increasing amounts of waste polymers generate enormous environmental problems. This study investigates catalytic cracking of mixture of polymers (HDPE, LDPE, PP, PS, PVC and PET) as an effective method to recycle these polymers and focuses on kinetic parameters of […]

Kinetic Study of Catalytic Cracking of Mixed Polymers (HDPE, LDPE, ...



Abstract: By use up novel catalyst the pyrolysis of mixed plastics has been reflected as an effective approach to convert waste plastics into environmental responsive and industrially valuable hydrocarbon gas and liquid products. Catalytic degradation is a hopeful alternative for municipal plastic wastes recycling. Further than 97% of a polymer […]

Catalytic Degradation of Mixed Polymers (HDPE, LDPE, PP, PS, PVC, ...



Abstract: Sulphide Dioxide (SO2) contaminant was captured selectively in a pilot scaled plant. It was reduced from 8000 ppm all the way to under 10 ppm. The gas flow rate is including 14 L/min and the ammine solution flow rate about 30 mi/min. The operation condition including flow rates, pH […]

Removal of SO2 Using an Amino Compound Solvent in a ...



Abstract: Most water recovery of mineral processing plants is done using of thickeners and filters. Filter included a porous surface with pressure drop on both sides, Water in the pulp passes through the surface and solid particles remain as a cake on it. The amount of non-renewable water processing plant […]

Determination of Suitable Filtration System in Order to Water Recovery ...



Abstract: Acclimation of nitrifying bacteria using inorganic carbon source (bicarbonate) and organic carbon source (bicarbonate + glucose) was performed in this study. Sequential batch reactors were inoculated by activated sludge (mixed culture of heterotrophic and nitrifying bacteria), and fed by synthetic wastewater contain high concentration of ammonium (1000 mg·L-1). Adapted nitrifying […]
