Thank you Mark for your answer. Actually this paper mill uses wastepaper as raw materials (not wood), so I suppose the Black liquor is not present? Yes I also think separating the streams for individual treatment is more proper. But for the mill in my case study, they mix all of wastewater fractions into only one stream.
