Combination of electro-Fenton (EF) process with other advanced oxidation processes (AOPs) is found very much effective for water and wastewater treatment. The combined including sono-EF (SEF), photo-EF (PEF), electro-peroxone, ferrate-EF EF persulfate allow enhancing the mineralization efficiency treatment as well reducing operational cost toxicity treated wastewater. Even though, there are sev...

Background Between 2000 and 2010, the consumption of antibiotics in 71 countries increased by 36% [1]. The rise of antibiotic consumption is expected to continue, considering the potential genetic mutation of super bacteria. Most antibiotics cannot be fully metabolised by the human body [2] and are excreted into the environment via wastewater effluents. Typical biological treatment processes, w...

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...

Wastewater reuse presents a promising solution to the growing pressure on water resources. However, wastewater reuse implementation faces obstacles that include insufficient public acceptance, technical, economic and hygienic risks and further uncertainties caused by a lack of awareness, accepted standards, uniform guidelines and legislation. So far, there are no supranational regulations on wa...

Growing demands for potable water have strained water resources and increased interest in wastewater reclamation for potable reuse. This interest has brought increased attention to endocrine-disrupting chemicals (EDCs) as emerging water contaminants. The effect of EDCs, and in particular natural steroid hormones, on humans is of heightened interest in the study of wastewater reuse in advanced l...

Extended-duration space travel and habitation require recovering water from wastewater generated in spacecrafts and extraterrestrial outposts since the largest consumable for human life support is water. Many wastewater treatment technologies used for terrestrial applications are adoptable to extraterrestrial situations but challenges remain as constraints of space flights and habitation impose...

in this work application of seven synthetic polymers as adsorbents for the removal of hg(ii) from aqueous solution was studied. the equilibrium studies are systematically carried out in a batch process, covering various process parameters that include agitation time, adsorbent dosage, and ph of the aqueous solution. variations of hg(ii) concentration in solution have been studied through measur...

ammonium ions wastewater pollution has become one of the most serious environmental problems today. the treatment of ammonium ions is a special concern due to their recalcitrance and persistence in the environment. in recent years, various methods for ammonium ion removal from wastewater have been extensively studied. this paper reviews the current methods that have been used to treat ammonium ...

background: yazd waste stabilization pond facilities consist of three stabilization pond systems, module 1, module 2 and module 3 that awsp module 1 has started its operation. the existing facilities have had several problems in their operation. the objectives of this research were to evaluate the performance of stabilization ponds in wastewater treatment of the city of yazd, due to several pro...
