As expected the answers to your question just complicate the issue even further. Hopefully some of the issues can be simplified. The best way of dealing with wastewater is to treat it to a standard (Solids, BOD and NH4) as set down in regulations and then discharge it back to the environment with a dilution factor of at least 10 to 1. This makes the water available for abstraction for any other use i.e. agriculture, industry or, following further treatment, potable. If the water is not put back into the environment and taken directly for potable use then it will (again) require two stages of treatment. The first is roughly the same as before but is designed as pretreatment simply to make it suitable as feedwater to an advanced process such as RO. As others have said this produces water which is akin to distilled water and, whilst great as industrial process water, it requires blending in order to make it suitable for potable uses. Wastewater can be used almost directly for agricultural purposes but poses threats to both to workers and consumers if precautions are not taken. Most countries have regulations requiring quality standards to be met. Most aquifers produce water which is suitable for direct consumption with just disinfection using chlorine.

Cher Peter

Comme si le traitement de l'eau était aussi facile que vous le décrivez.

Que faites vous des diverses pollutions bio chimiques et chimiques dissoutes.

Chacune ne peut être traitée qu'individuellement car personne encore au monde n'a inventé de processus aussi pointu pour une telle performance.

Non la seule solution pour le traitement d'eau c'est la biotechnologie en préservant l'eau souillée de toute pollution chimique ou bio chimique 

 

Dear Peter

As if the water treatment was as easy as you describe.

What do you of organic pollution chemical and chemical dissolved.

Each can be treated as individually because nobody even in the world invented process also pointed to such a performance.

No the only solution for the treatment of water it's biotechnology in preserving water contaminated from pollution chemical or bio chemical
