Removal of benzene from wastewater via Fenton pre-treatment followed by enzyme catalyzed polymerization

This study investigated the feasibility of a two-step process for the removal of benzene from buffered synthetic wastewater. Benzene is outside the scope of enzymatic removal. In order to remove it from wastewater using enzyme, its pretreatment by modified Fenton reaction was employed to generate the corresponding phenolic compounds. In the first phase, the optimum pH, H2O2 and Fe2+ ...

Role of final cover soil in regulating volatile organic compounds: emissions from solid waste disposal sites in developing countries

The objective of this study was to investigate the emission of Volatile Organic Compounds (VOCs) from solid waste disposal sites and their remediation at final cover soil. This research was conducted using field cover soil lysimeters placed at the surface of a solid waste dumping area and batch experiments in the laboratory. It was found that benzene, toluene, chloroform and perchloroethylene ...

Impact of carwash discharge on stormwater quality (Toulouse, France)

The contribution of discharge from carwashes to pollutant levels in stormwater was evaluated. Five carwashes and two outlets in the city of Toulouse (France) were selected. Water samples were collected from December 2006 to December 2007. Concentrations and loadings of classical water quality parameters (conductivity, pH, turbidity, chemical oxygen demand, nitrogen, phosphorus, ammonium, nitrate, ...

Back-propagation neural network for performance prediction in trickling bed air biofilter

Experimental studies were carried out with a laboratory-scale biotrickling filter to treat a gaseous stream contaminated with benzene, toluene and xylene (BTX) operated in a continuous mode. The biotrickling filter initially acclimatised with toluene was used to treat BTX compound individually at loading rates ranging from 7.2 g/m³hr to 62.2 g/m³hr, operated in a sequential mode. The results ...

Questions and answers about oil and gas wastewater spills

Nearly 3 million gallons of briny water generated by crude oil production has leaked from a North Dakota pipeline and reached two creeks, making it the biggest spill of this type of wastewater since the state's Bakken formation oil boom began in 2006. Here are some questions and answers about oil and gas saltwater spills: Q: What does this liquid consist of, and where does it come from? A: ...
