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 this backwash speed is 25 mc/mp*h.
Which is the good value, because the difference is very high between the two values (192.01 mc/h vs. 78.54 mc/h)?
Thanks in advance
