Dear Dorji,

Anaerobic treatment methods are generally used for wastewater which difficult to treat and has high organic pollution load. However it is possible to see that there are literature informing that it can also be used for domestic wastewater. Which of these did you target for the treatment? Accordingly, we will need to find a recipe.

Kind Regards.

Dear Dorji

There are many typrs of waste waters and depend on what kind of waste water you want to treat you should search to design your system, and as this DR. Olcayto mentioned the anaerobic is used to treat organiuc pollutants.

another example is here for anaerobic bio-filtration treatment is hexavalent chromium,

please see the attched paper about Study on anaerobic treatment of wastewater containing hexavalent chromium. where the Synthetic wastewater prepared with potassium dichromate was used for screening process conditions,

kind regards,

i agree with comment of keskinkan above
