When comparing ,wastewater discharge, standards, it can be seen that limits vary considerably—although there is some commonality in determinants, such as TSS, COD, and BOD, TN. It is noticeable that the planned Indian standards have the strictest levels in terms of BOD 5, TSS, and TN removal, followed by Peru, Romania and Tanzania.
