Hi Hung Bui, you should register the water consumption over 24 hours of all water sources and take samples every 2 hours and analyze them not only BOD, but also COD because the COD:BOD ratio shows you the biodegradability of the pollutants. Check also if the mill uses chlorination for pulp bleaching, which will result toxic chloroorganic pollutants. In any case you should run continuous degradation tests for the determination of process parameters.

Thank you Imre for your answer. I am very sorry because I have not given all the data. I will edit my post now. The COD is 5000-12000 mg/L. Yes I believe the sampling approach you suggested is very essential. But the company only gave me the data which I have mentioned all in my post.
