I am trying to find the density of a municipal WWTP sludge at 30% dry solids,lets say in lbs/ft3 (the sludge is a mix of primary and secondary, no digestion). I also want to land apply it, so it has to be mixed with lime for stabilization. (I would also like to know the mixing requirements and typical density of that as well)
I have been researching this, but the numbers I am finding are all over the map.
Is there a good table for % dry solids versus lbs/ft3? Or a good calc?
