Dear every country has its own limits, like USA, European union, Australia etc. But I think yet those of the FAO are followed by most the countries where there are no such standards are developed.

yes preferably, P

Thank you dear Mr. Abdul Ghafoor and dear Mr. Ali Altaee for your valuable information. Dear Mr. Ali Altaee , is this an Australian standard? or else? As I did not experience these limits here in my country  (Iraq ). Thank you in advance. 

Dear Nabeel, There is interantional standards but that like water quality standards by WHO but many countries develop their own environmental [policies and discharge routes. If you discharge to river and lakes then standards whould be more restricted than discharge to seawater. You need a research program to develop the best standards for country but the values i sent you could be used as a benchmark

Regards..Ali

Dear All,

Yes. Off course many country has been set up their own sanitary sewage effluent standard which is more or less close to each other. I think major significant polluting parameters or indicators are DO, BOD, COD, NO2 , NO3 and other parameters depending on the types and nature of waste water, sources, level of treatment, river water to be used for drinking and other purposes, treatment technology used etc.
