Phenolic and petrochemical wastewater treatment in AnMBR under extreme conditions: High salinity, high temperature, and high concentration of toxic compounds

Anaerobic digestion (AD) is a biochemical process in which organic matter is converted into biogas in a series of biochemical reactions. The development of high-rate anaerobic reactors (HRAR) led to the breakthrough of full-scale applications of AD for the treatment of industrial wastewater. HRARs, such as the upflow anaerobic sludge blanket ...

Anaerobic Membrane Bioreactors under Extreme Conditions: Mesophilic and Thermophilic Degradation of Phenol at High Salinity

Industrial wastewaters generated in chemical industries are often characterized by extreme conditions, such as the presence of complex, recalcitrant, and toxic aromatic compounds, high temperature, and high salinity. The mentioned conditions predominantly occur when chemical industries reduce process water use or strive for closing water loops....

Model Predictive Control of Water Level and Salinity in Coastal Areas

POLDERS are low-lying and artificially drained areas surrounded bywater storage canals. In low-lying delta areas such as theMississippi delta in Louisiana (USA), the Ganges-Brahmaputra delta (Bangladesh), or the Rhine-Meuse delta (The Netherlands), polders experience surface water salinization problem due to saline groundwater exfiltration,...

A theoretical basis for salinity intrusion in estuaries

Saltwater intrusion is a crucial issue in estuaries. The spread of salinity is described by the dispersion coefficient. A purely empirical equation which links the effective tidal average dispersion to the freshwater discharge was developed by Van der Burgh [1972]. Combining it with the salt balance equation, Savenije [1986] derived a one...

Analysis and Remediation of the Salinized, Damour Coastal (Dolomitic) Limestone Aquifer in Lebanon

Coastal aquifer management has recently emerged as a main scope in groundwater hydrology, especially in arid and semi-arid zones. About two thirds of the human population are currently gathered close to shorelines relying on coastal groundwater resources. Worldwide, these systems are subject to quality deterioration due to a multitude of...

Enhanced Biological Phosphorus Removal: Metabolic Insights and Salinity Effects

Enhanced biological phosphorus removal (EBPR) is a biological process for efficient phosphate removal from wastewaters through intracellular storage of polyphosphate by polyphosphate-accumulating organisms (PAO) and subsequent removal of PAO from the system through wastage of sludge. In comparison to physical and chemical phosphorus removal...

Prediction in Ungauged Estuaries

Estuaries have been used for settlement by humans since 5000-9000 years ago [Day et al., 2012]. The calm environment and nutrient-rich soil encouraged the development of ports and agriculture. Over-development however has put estuaries in unhealthy condition, where the water is polluted (excessive nutrient or salt intrusion problem) and natural...
