Hello to this day nobody should engage in such discussion on reuse of wastewater from both of domesticity than industrials.
All of these wastewater are steeped in chemical that no effective system is able to eliminate such as physicochemical treatment. This chemical pollution is mostly dissolved so invisible.
Also eliminate it to implement a targeted system. But targeted toward what kind of chemical molecule? What will be the treatment targeted to one different chemical reactions? This must be added the presence of oxygen.
We can realize that sanitation services play the sorcerer's apprentice without worrying about the consequences of the impact of their actions on the environment and on humans.
All of these chemical pollution will disperse in the environment, mainly in natural water environments, essential elements in the condition of life on Earth.
It's beautiful to launch claims of recycling under the guise of ecological ideas in where the preservation of a scarce resource. For me any idea of liquid from the management of wastewater reuse is a crime against humanity.I'm talking about management, because in all the descriptions of management stations doesn't appear anywhere a semblance of purification treatment. Filtered, we put aside, rejected a liquid.
What is set aside will be dispersed in the environment once again relying on any recycling as the farmland of sludge of dung-spreading totally impregnated of chemical
PS: physico-chemical treatment is a process very expensive who loses his purification performance from its use. What in means that we know not at what point there is no function

None of the above is true. There are potable domestic wastewater reuse systems that have operated for many years. Windhoek SA is a potable system operating successfully since the 1960s. See 2017 WHO Guidance:

Yes. In the guise of common effluent treatment plants and treated effluent recycling systems. public are being misled by the polluting industries and Federal Govts., Simply the pollutants are being converted from one from to another form , the same could not be completely eliminated. Once the mistake of over exploiting natural resources for industrial and domestic greed and materliasm , the resultant pollutants are irreversible and we need to face the consequences in one form or other.

The vast majority of chemicals and pollutants in wastewater can be either removed from the waste stream or converted into innocuous forms. Is not taking water from the environment and then discharging it in a polluted form a far greater waste of resources than recycling?

Please name a contaminant in common wastewater that cannot be treated?

Not true. Technology has progressed significantly. Read the recent WHO water reuse guidance cites in my response to lyseconcept above.
