Dear Sergio, The question ...

Dear Sergio,
The question is so open ended. If you come up with specific industry even in foods, there are many type of industry discharging different pollution loads. Confectionery, Can Foods, Syrups etc. Poultry and Meat has different Discharge Loads.
The high pollution load say BOD 2000+ and COD 6000+ normally good to be treated by the Scheme
Scheme 1: Anaerobic Digestor (Reactor)----->Chemical Treatment (may or may not)---->Aerobic Treatment----->Post Filtration (Depends upon output requirement)
Scheme 2: Anaerobic Treatment (Reactor)------>Aerobic Treatment------>Post Filtration
Scheme 3: Chemical Treatment ----> 2 Stage Aerobic Treatment ----->Post Filtration
The treatment scheme depends many factors, some listed as
Inlet Pollution Load Vs Outlet Parameter requirement
Type of Pollution Load, easily Biodegradable or slow biodegradable or Major part Chemically Precipitated Out or Biologically Degradable

I agree, The rule of thumb cut off value is 2000 BOD which i use. Less than 2000, use aerobic systems like activated sludge of fixed film technologies. Greater than 2000 is a candidate for anaerobic treatment. There are many anaerobic alternatives including low rate and high rate like USAB and MFT. To reuse water follow activated sludge treatment call secondary effluent by with a multi-media or micro filtration the RO. Anaerobic may need an activated sludge and then membrane and RO. Post secondary depends upon water quality needed.

Bonjour
La quantité de la masse de matière organique qui entre sur une STEP ressort automatiquement sous la forme de résidus boueux. S'il y avait de la digestion anaérobie , de l'abattement par le chimique, il n'y aurait pas besoin de la filtration.
S'il y avait du traitement anaérobiec dans le réacteur puis du traitement aérobie avec un abattement réel d'épuration il n'y aurait pas besoin de la filtration.
S'il y avait un traitement chimique puis ensuite une traitement aérobic avec un abattement réel d'épuration il n'y aurait pas besoin de la filtration.
Ensuite comme expliquer qu'un effluent aérobic puisse subir un traitement anaérobic? par quel miracle? quelle est la méthode? quels sont les résultats de performance?
Ensuite comment peut-on expliquer que derrière un traitement chimique on puisse faire un traitemetn aérobic?PAr quel miracle ?
En quoi peut bien consister le traitement aérobic? quel est l'outil ?
Hello
The quantity of the mass of organic matter that enters a STEP is automatically in the form of muddy residue. If there is anaerobic digestion of the abatement by the chemical there would not need filtration.
If there is the processing of anaerobiec in the reactor then the aerobic treatment with a reduction of treatment he would not need filtration.
If there was a chemical treatment and then an aerobics with a real reduction treatment sewage there would not need filtration.
Then as we explain that an aerobic effluent can undergo anaerobic treatment? What miracle? What is the method? What are the performance results?
Then how can we explain that behind a chemical treatment we can do an aerobic traitemetn? What miracle?
In what may well be the aerobic treatment? What is tool?
