Technical and scientific developments have facilitated an increase in human life expectancy quality, which is reflected a large growth of global population [...]

Chlorophenol wastewater belongs to highly toxic industrial wastewater, which can cause serious harm the environment and human health if not treated effectively. The current treatment methods for chlorophenol are divided into physical, chemical, biological methods. physical adsorption experiment found that monodisperse magnetic nano-column was prepared by solvothermal method, could remove 91.5% ...

Limited available water resources have rendered wastewater reuse an important issue to specialists in most developed countries, today. The current study works on membrane filtration for treatment of industrial wastewater. By comparing the two methods of membrane bioreactor (MBR) and hybrid membrane electro bioreactor (MEBR) processes, it finds that earlier fouling in the membrane occurs in the ...

application of granular activated carbon (gac) in adsorption process has been studied for the advanced treatment of municipal and industrial wastewater. because of entering poisonous compounds such as furfural, phenol and sulfides into the oily wastewater of tehran refinery, biological aeration basins of wastewater treatment unit may not have the desired performance of cod reduction. in this st...

Dissolved organic nitrogen (DON) derived from wastewater effluent can participate in reactions that lead to formation of nitrogenous chlorination by-products, membrane fouling, eutrophication, and nitrification issues, so management of DON is important for both wastewater reuse applications and nutrient-sensitive watersheds that receive discharges from treated wastewater. This study documents D...

background: hospitals generate relatively large quantities of wastewater that may contain various potentially hazardous ma­terials; therefore the proper management of hospital wastewater is essential. methods:   in this cross-sectional study, the quality and quantity of wastewater in the hospitals of tehran university of medi­cal sciences (tums), tehran, iran, were studied and the suitable meth...

More than 40% of the homes in Georgia use onsite systems to manage household wastewater. Because of water quality concerns as the number on onsite systems increases, advanced wastewater treatment components to reduce biological oxygen demand (BOD), total suspended solids (TSS), and nutrients are more commonly used.. The objective of this study was to evaluate passive, low-maintenance onsite sys...

Microbial fuel cells (MFCs) have been used to produce electricity from different compounds, including acetate, lactate, and glucose. We demonstrate here that it is also possible to produce electricity in a MFC from domestic wastewater, while atthe same time accomplishing biological wastewater treatment (removal of chemical oxygen demand; COD). Tests were conducted using a single chamber microbi...

Chrome tannery wastewater causes serious environmental hazard due to its high pollution potential. As a result, rigorous treatment is necessary for abatement of pollution from this type of wastewater. There are many research studies on chrome tannery wastewater treatment in the field of physical, chemical, and biological methods. In general, biological treatment process is found ineffective for...
