Soil-washing is a potential technology for the disposal of soil contaminated by e-waste; however, produced soil-washing effluent will contain polybrominated diphenyl ethers (PBDEs) and large number surfactants, which are harmful to environment, so treatment PBDEs recycling surfactants key application technology. In this study, coconut shell granular-activated carbon (GAC) was applied remove fro...

Optimizing the characteristics of granular activated carbon (GAC) can improve performance biologically (BAC) filters, and iodine value has always been principal index for GAC selection. However, in this study, among three types treating same humic acid-contaminated water, one had an 35% lower than other two, but dissolved organic removal efficiency its BAC was less 5% away from others. Iodine f...

Abstract The herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) has been detected in water bodies worldwide, precluding their use for supply. Despite this, scientific studies assessing the behavior of herbicides treatment systems are scarce, which motivated this study on 2,4-D removal. removal and its relationship with absorbance were investigated using a pilot system comprising coagulation, sedi...

Reclamation and reuse of wastewater are increasingly viewed as a pragmatic tool for water conservation. Greywater, which includes from baths, washing machines, dishwashers, kitchen sinks, is dilute stream, making it an attractive stream extraction non-potable water. However, most previous studies primarily focused on passively aerated biological physicochemical treatment processes greywater tre...

The identification of certain organic compounds in drinking water has led water treatment specialists to be increasingly concerned about the eventual risks of such pollutants to the health of consumers. Our experiments focused on the role of ozone and granular activated carbon in removing mutagenic compounds and precursors that become toxic after chlorination. We found that if a sufficient dose...

The widespread use of pesticides for agricultural purposes results in their presence the environment. Pesticide occurrence is causing potential negative impacts on human health and environmental deterioration general. One interdisciplinary field to implement a technology converting conserving resources bioelectrochemistry. An integrated system based bioelectrochemical processes, namely Bioelect...

The aim of this study was to characterize landfill leachate of Çorlu that was heavily industrialized, and to examine the application of coagulation-flocculation and adsorption for the treatment of this leachate. This deposited area is non-regulated and municipal and industrial wastes are deposited uncontrollably. The experiments were conducted to investigate the combined process of coagulation-...

in this study two identical anaerobic completely mixed fluidized bed reactors with gac and sand media were employed for cod & phenol removal. at loading rate of 1.6 g phenol l-1d-1, the efficiency of phenol removal in gac & sand reactors were 97.7% & 74%, respectively. at high loading rate of phenol (6.09 g phenol i: 1d1) the efficiency of phenol removal in gac reactor was better than 95%. in g...

Chlorinated ethenes are among the most frequently occurring groundwater contaminants. Pump and granular activated carbon (GAC) treatment is applied to limit spreading from point contaminations. Perchloroethene (PCE) trichloroethene (TCE) sorb well GAC, but dichloroethene (DCE) vinyl chloride (VC) poorly, thereby defining a low efficiency seen as amounts of GAC used. On other hand, ozone reacts ...

Experiments were carried out to study adsorption/desorption of volatile organic compound (VOC) on the activated carbon fiber (ACF) under dynamic conditions. The primary objective was to experimentally demonstrate the suitability of ACF in effectively adsorbing VOCs from inert gaseous stream under varying operating conditions, and compare its performance vis-à-vis that of the other commercially ...
