Well, since a sand filter is basicly water flowing throught sand of different grades, did you look up Darcy's Law?

What I actually looking for is, do anybody have any data or tables or figures about the normal flux that run through the sand filter...

If you look up manufacturers of particular filters, they will always provide engineering data on their performance such as flow and expected $$\Delta P$$.

15m/hr filtration velocity (superficial) is good enough.
