The typical smelting wastewater is with characteristics of high concentration TDS, conductivity, heavy metal ions, and low COD. ultrafiltration (UF) reverse osmosis (RO) an attractive technology to reclaim reuse this kind wastewater. In work, Coagulation-flocculation-sedimentation (CFS) multi-media filter (MMF) was used as the pretreatment processes. UF, RO (CRO) processes applied advanced trea...

In the era of freshwater scarcity, world seeks to limit overexploitation all accessible resource and also recover potable water by treating wastewater. Various domestic, agricultural industrial activities lead in generating high amount wastewater from which can be recovered for human needs. Over many years, conventional filtration process has gained success some extent effluents treatment dispo...

Forward osmosis (FO) is a membrane separation technology that has been studied in recent years for application in water treatment and desalination. It can best be utilized as an advanced pretreatment for desalination processes such as reverse osmosis (RO) and nanofiltration (NF) to protect the membranes from scaling and fouling. In the current study the rejection of trace organic compounds (TOr...

Background: Pharmaceuticals, like antiepileptic drugs, are found regularly in surface waters, and consequently, advanced waste water treatment technologies are discussed for substance elimination. Because antiepileptic drugs have shown to transform to more toxic substances, their behavior in these treatment processes and resulting effects on ecotoxicity should be investigated. To validate if wa...

background: venoarterial extracorporeal membrane oxygenation (ecmo) provides systemic arterial support without directly unloading the left heart, which causes an elevated left ventricular (lv) pressure. the aim of the present study was to investigate the adjunctive application of the impella device for lv unloading in patients during ecmo. methods: this retrospective cohort study included patie...

Diclofenac is a drug with an analgesic effect that accumulates and results in adverse consequences if it enters the human body more than needed. Low concentrations of diclofenac have been detected in different water sources through leachates of landfills and agricultural areas, human and animal excreta expired drug discharge and hospital effluents. To eliminate diclofenac from the aquatic e...

Nanofiltration is increasingly gaining attention in many separation and treatment processes such as water softening, color removal and separation of medicines. Nanofiltration membranes are often negatively charged, displaying separation characteristics in the intermediate range between reverse osmosis and ultrafiltration. In this research, a novel nanofiltration membrane prepared with poly(amid...

Landfilling although is a popular and economical method of solid waste disposal is associated with the risk of environmental degradation due to inherent problem of leachates. Leachate continues to be of concern especially when it comes into contact with ground water and surface water. Thus a proper treatment of leachate is essential prior to discharge of leachate into surface and subsurface env...

The aim of this work is to study the degradation and mineralization of antibiotic ofloxacin in aqueous medium using the Electro-Fenton method as advanced oxidation technology. In this context, Pt/carbon-felt cell was used to investigate the influence of various parameters including initial pH, different supporting electrolytes, different metal ions as a catalyst and antibiotic concentration ove...
