There are provided systems () and processes for the selective removal of cyanide from a wastewater stream () comprising cyanide and an amount of organic compounds therein.

Catalytic oxidation system and process for selective cyanide removal

Methods of treating a high suspended solids liquor having a waste stream and a suspended solids content including powdered activated carbon and biological material by contacting the high suspended solids liquor with a membrane unit are disclosed. Methods of treating a waste stream by combining the waste stream with powdered activated carbon and biological material to produce the high suspended solids liquor and contacting the high suspended solids liquor with a membrane unit are also disclosed. Treatment systems including a membrane unit fluidly connected to a source of a high suspended solids liquor are disclosed. Treatment systems including a bioreactor fluidly connected to a source of a waste stream and a membrane unit are also disclosed.

Systems and processes for the treatment of waste streams allowing direct activated carbon and membrane contact

The invention is directed to a method and apparatus for treating wastewater. The wastewater treatment system includes a bioreactor including activated carbon and a first biological population. The wastewater treatment system may also include a membrane bioreactor and/or a wet oxidation unit.
