摘要
(WO2013126625)
A system adapted to condition an initial water feed stream into a treated water stream and to discharge the treated water stream. 
The initial water feed stream includes at least one of a plurality of particles; an oil; a volatile organic compound; a hydrogen sulfide; a non-volatile compound; a heavy metal; and, a dissolved ion. 
The system includes a particle and oil removal subsystem adapted to treat the initial water feed stream to remove the plurality of particles and the oil to form a first partial treated water stream, a chemical oxygen demand reduction subsystem adapted to treat the first partial treated water stream to remove the volatile organic compound, the hydrogen sulfide and/or the non-volatile organic compound to form a second partial treated water stream, and a heavy metal and dissolved ion removal subsystem adapted to treat the second partial treated water stream.
