Continuously seeking the improvement of environmental protection, limitation exhaust emissions is significance for tire manufacturing industry. The aim this study to assess potential biofiltration treatment such gaseous emissions. This work highlights that able remove both hydrophilic and hydrophobic compounds within a single pilot unit biofiltration. Due Ethanol/Alkanes ratios (95/5 80/20), hi...

A simple and effective method was developed using phenol formaldehyde (PF) resins to immobilize hydrous ferric oxide (HFO) onto granular activated carbon (GAC). The resulting sorbent possesses advantages for both the ferric oxide and the GAC, such as a great As-affinity of ferric oxide, large surface area of GAC, and enhanced physical strength. The studies showed that within one hour this sorbe...

The adsorption of Escherichia coli on different activated carbons has been studied. The activated carbon samples used have been characterized, determining their surface area, pore size distribution, elemental analysis, mineral matter analysis and pH of the point of zero charge. The adsorption capacity of these carbons increased with their hydrophobicity and macropore volume. The number of bacte...

The management of mature landfill leachate (MLL) represents an increasingly crucial issue to tackle. In this study, the feasibility integrated treatment was investigated at laboratory scale using synthetic with objective maximizing recovery potentially useful compounds present in (especially ammonia nitrogen). First, order remove heavy metals, active filtration MLL carried out zero-valent iron ...

AND YUEFENG F. XIE aloacetic acids (HAAs) and trihalomethanes (THMs) are the major disinfection by-products (DBPs) found in chlorinated drinking water. Nine species of HAAs are commonly found in chlorinated water: monochloroacetic acid (ClAA), monobromoacetic acid (BrAA), dichloroacetic acid (Cl2AA), bromochloroacetic acid (BrClAA), dibromoacetic acid (Br2AA), trichloroacetic acid (Cl3AA), brom...

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...

Evaluation of the Removal Efficiency of Perfluoroalkyl Substances in Drinking Water Sophie Englund Per-and polyfluoroalkyl substances (PFASs) are chemicals that have been used for over 50 years. They are both hydrophobic and hydrophilic, which make them useful in a wide range of products, both in the domestic and industrial market. Recently, the global attention on PFASs has increased due to th...

Abstract Because of the remarkable chemical structure perfluoroalkyl and polyfluoroalkyl substances (PFAS), as well complex conditions water, selecting an appropriate adsorbent for treating PFAS is critical. Adsorption needs to be environmentally friendly, low cost, consider types adsorbents that work in mixed solutions. In present study, we used estimate activity. This research aimed evaluate ...

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.
