Thanks a lot. but the issue is that the purpose of reuse is for industrial consumption and the problem is that the industries are so diverse. anyway I guess TDS is more important (although I am not sure). because the secondary treatment unit can decrease the COD, but it does not have any influence on TDS. So TDS is more critical. if you refer to Ken's comments it can this issue more clear for you. thanks
