Hello,
I try to design a filter with a granular media consisting of a mixture of pyrolusite and quartz (Q = 40 mc/h)
I found in the technical sheet of the pyrolusite that the backwash speed is 25 gmp/ft2 (~62 mc/mp*h). But, I found in the data sheets from various equipment manufacturers that...

Thank you Ashtree for your response.
So,my answer for your question is:
Does the water contain high levels of tannins , sulphur or chlorides?
no tannins, no sulfur and chlorides is around 100 mg/l
How are you measuring the manganese?
two methods: 1 - in site with Hach Lange DR900 colorimeter...
I have the fallow application:
Pyrolox / sand filter with 2000 mm tank diameter. I fill the tank with 420 kg of quartz 2-4 mm on base. After that I put, in the succesive layer, 2360 kg of quartz 0.8-2 mm and 2120 kg pyrolox 8x20.
Work condition is: filtering flow is 40 mc/h, backwash flow is 192...
