In this project, the degradation of synthetic wastewater comprising p-nitro toluene (PNT) is investigated using UV/TiO2 process. PNT as a pollutant has a very harmful effect on the environment and human hormones. TiO2 is one of the best metal oxides it has photo catalyst role. The full factorial design (FFD) of experiment is employed to investigate the effect of working va...

Phenol and its derivatives are one of the most common contaminants in the aquatic ecosystem. Because of high toxicity of 2,4-DCP for aquatic life, resistance to biodegradation and potential for biological accumulation it is known as a priority contaminant in the aquatic environment. Advanced Oxidation Processes were successfully used for degradation of non-biodegradable contaminants that are re...

In a system, prediction of remaining useful lifetime (RUL) of servicing before reaching to a specified breakdown threshold is a very important practical issue, and research in this field is still regarded as an appreciated research gap. Operational environment of an equipment is not constant and changes regarding to stresses and shocks. These random environmental factors accelerate system deter...

During past decades, increased wastewater production by human activities intensified the problem of wastewater usewithout causing undesirable impacts on the environment and human life. However, practice of wastewater use inirrigation crops and green spaces needs careful control because of the potential presence of unwanted constituents such asheavy metals and organic contaminants. This research...

the resource intensive human activities (such as mining and extraction of mineral oils for betterment of life and modernization of society) have increased environmental pollution several folds. products of mining and petrochemical industries are advantageous for the modern society. but waste generated such as btex from such industries are carcinogenic, toxic and causes adverse effects on enviro...

the “driving force - pressure - state - impact – response” modeling framework isadopted to consider the formation mechanisms of environmental risks and the requirements ofecological environment protection. moreover, a systematical index system and evaluation model forthe measurement of the coastal ecological security level is put forward in this paper to assess thestate of coastal ecological en...
