Hi Cees,

I hope all is well. In response to your questions the following.

1. To answer this we need to know the type of media used at the moment. We have a filter media with a specific surface are of ~160 m2/m3  (http://www.qmes.nl/products/biofill/)  which is very open. Also the type of industry play a role. If it is food industrial containing FOG and there is not a properly working FOG removal system like a DAF for example than these solids can clog the media. 

2. Answered above, install a properly working solids removal system.

3. You only talk about BOD removal, what about nutrient removal. You have to take this into account as well when dimensioning the system.

I hope these answers are of help.

Best regards,

Robert Wagenveld
