Hi Alessandra
Unfortunately, there are no international rules for wastewater treatment much less a single design & operation standard; it's all site-specific. You need to know exactly where the pant will be built to hone in on effluent standards. For instance, if you are building a consumer wastewater treatment plant in a specific USA town, there may be local, county, state, and EPA rules to which you must adhere.
