Abstract Abatement of water pollution is being a major concern to be dealt with, as the scarcity for basic needs human beings increasing drastically. As part diminishing pollution, treatment industrial wastewater prior disposal plays paramount role. Due typical characteristics pesticide, intermediate waste also challenging issue. In this study three different sequential methodologies (Methodolo...

Membrane biological reactors combine the use of biological processes and membrane technology to treat wastewater. The use of biological treatment can be traced back to the late nineteenth century. It became a standard method of wastewater treatment by the 1930s (Rittmann, 1987). Both aerobic and anaerobic biological treatment methods have been extensively used to treat domestic and industrial w...

The bucket reactors based wetland system were adopted for the treatment of pulp and paper mill wastewater using two macrophytes namely Typha angustifolia and Canna indica. The study was carried out for the treatment of wastewater collected from primary clarifier overflow (E1) and wastewater after the partial aerobic treatment of primary clarifier overflow (E2). Effectiveness of the two macrophy...

Abstract Wastewater pollution from industrial sector has tremendously increased in recent years and posed severe environmental health problems many countries worldwide. Humans other living organisms need clean water to sustain life performing daily activities, such as growing crops agriculture, mining, manufacturing. However, lack of effective treatment poor management sources caused by wastewa...

The selection of an effective water treatment technology is the important issues that relatively dealing with pollution problems, some pollutants need more than conventional facilities to be treated and discharged within national standards. This study highlights advanced methods related chemical oxidation, which used in types such as heavy metals, pesticides, dyes, etc. demonstrate their effect...

Wastewater treatment plants (WWTPs) are a significant source for poly-/perfluoroalkyl substances (PFASs) entering the environment. The presence of PFASs in twenty-eight municipal WWTPs from eleven cites in economically developed areas of China were screened. Overall, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) were dominant in wastewater and sludge, and were not effec...

one of the major environmental problems in the world, especially in iran is deficiency of water resources. this with respect to the entrance of wastewater (especially industrial wastewaters due to their toxic effects) into the water bodies emphasizes the importance of wastewater treatment. heavy metals such as cadmium, lead and vanadium are part of oil and hence are of the major pollutants prod...

Victoria Harbour has received substantial loadings of pollutants from industrial and municipal wastewater discharged since the 1950s. Inputs of contaminants have declined dramatically during the last two decades as a result of better controls at the source and improved wastewater treatment facilities. To assess the spatial and temporal changes of metal contaminants in sediments in Victoria Harb...
