Acidic mine drainage (AMD) contains large amounts of heavy metal ions and SO42, which can pose serious risks to human and environmental health. Anaerobic bioreactors are considered to be suitable methods for the treatment of acidic effluents due to some advantages such as the need for a small area, easy control, and simultaneous removal of […]
Caustic soda is a substance used for sweetening hydrocarbon products in oil refinery, gas and petrochemical units. The caustic soda-generated salts are increasingly formed during the process of removing impurities like mercaptans, sulfides and nitrates, which finally leave process system through spent caustic discharge. Spent caustic discharge into environment is prohibited due to the presence […]
Water is an essential component in the world. The presence of heavy metals in water has dramatic effects on health and ecological process in the environment. Heavy metal pollution in water bodies is an existing and developing problem in the world. There are several methods for removing these pollutions in water. A photocatalytic degradation is […]
