The safe disposal of liquid wastes associated with oil and gas production in the United States is a major challenge given their large volumes and typically high levels of contaminants. In Pennsylvania, oil and gas wastewater is sometimes treated at brine treatment facilities and discharged to local streams. This study examined the water quality and isotopic compositions of discharged effluents,...

Pollutants in dye wastewater significantly vary due to the large number of dyes and other chemical compounds used in dyeing processes. The major compounds in dye wastewater are desizing and scouring agents, bleaches, reducing agents, detergents and wetting agents, finishing agents, organic acids and dyes, and fluorescent brighteners1). Physical, chemical and biological methods have been applied...

In peri-urban areas in low-income countries, conventional centralized approaches to wastewater management have generally failed to address the needs of communities for the collection and disposal of domestic wastewater and faecal sludges from on-site sanitation. There are opportunities for implementing wastewater management systems based on a decentralized approach that may offer opportunities ...

BACKGROUND The scarcity of water supply in many arid regions, combined with the need for disposal of large volumes of wastewater, has led to an increased use of recycled water for landscape irrigation. Although this practice has been employed for decades in many parts of the world, public health officials recently have begun to express concerns about the potential for wastewater-derived trace c...

Tomato packers often struggle to find ways to reuse the large volumes of wastewater generated during the tomato cleaning and sanitizing processes due to high transportation costs for off-site disposal and strict surface water discharge regulations in Florida. Information about the composition of tomato packinghouse wastewater and the likely sources of major wastewater constituents might provide...

Wu, Ping F. and Gauri S. Mittal. 2011. Characterization of provincial inspected slaughterhouse wastewater in Ontario, Canada. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada. 53: 6.9 6.18. Characteristics of slaughterhouse wastewater and its suitability to be land-applied for agricultural use were investigated. A survey was sent to slaughterhouses located in Ontario, Canada, ...

The objective of this study was to assess the environmental impact of a submerged anaerobic MBR (SAnMBR) system in the treatment of urban wastewater at different temperatures: ambient temperature (20 and 33°C), and a controlled temperature (33°C). To this end, an overall energy balance (OEB) and life cycle assessment (LCA), both based on real process data, were carried out. Four factors were co...

The pressure on water resources caused by accelerated urbanization, the inadequate management and disposal of wastewater and the implementation of sophisticated treatment systems which sometimes with low efficiency and coverage are some of the problems to be solved with alternative and innovative strategies that be in harmony with the recent trends on water management. One of these strategies i...
