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...

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...

Developing low-carbon advanced processes for sustainable wastewater treatment is of great importance to increase bioenergy recovery and reduce the greenhouse gas effect. In this study, influence adding 25 g/L granular activated carbon (GAC) on process performance was studied with a lab-scale GAC amended anaerobic dynamic membrane (G-AnDMBR) used treat real domestic wastewater, which compared co...

The activated carbon loaded with manganese (GAC-Mn) was prepared and optimized for the treatment of acid red wastewater. Scanning electron microscope-energy dispersive spectrometer (SEM-EDS), Brunner-Emmett-Teller surface area (Sbet) analysis results revealed that successfully on larger specific obtained. kinetics study indicated removal GAC-Mn followed pseudo-second-order model.

Landfills generate leachate that contains elevated concentration of contaminants and is hazardous to human health and the ecosystem. In this study, the mixture of granular activated carbon and cockle shells was investigated for remediation of COD and ammonia from stabilized landfill leachate. All adsorbent media were sieved to a particle size between 2.00 and 3.35 mm. The optimum mixing ratio, ...

Granular activated carbon (GAC) adsorption is an effective treatment technology for the removal of synthetic organic chemicals (SOCs) from drinking water supplies. This treatment process can be expensive if not properly designed. Application of mathematical models is an attractive method to evaluate the impact of process variables on process design and performance. Practical guidelines were dev...

Granular activated carbon (GAC) is the most widely used and well-established treatment technology for removal of per polyfluoroalkyl substances (PFAS) contaminants from drinking water wastewater. After GAC has reached end its useful service life become “spent carbon,” it common practice in industry to thermally treat a process known as reactivation. The reactivation volatilizes destroys adsorbe...

This paper presents experimental results of the ozonation of a model aromatic sulphonic compound, 1,3,6-naphthalenetrisulphonic acid (NTS), in the presence of different activated carbons with different physical and chemical surface properties. Carbons used were commercial activated carbons (Ceca AC40, Norit, Merck, Witco, Ceca GAC, Filtrasorb 400, Sorbo) with or without demineralisation pre-tre...

The results of the study of removal of nonylphenol, octylphenol and their ethoxylates from real industrial and municipal wastewater are presented. Industrial wastewater was pre-treated by coagulation with FeCl3 and adsorption on zeolite, before discharging into municipal sewer system. Their removal efficiencies in primary sedimentation tank of municipal WWTP were very low. From the practical po...
