Calculating percent solids in sludge
WebMay 6, 2014 · Let’s look at how to convert the concentration in mg/L to an amount in pounds (lbs). The formula for this conversion is: Lbs = Volume (MG) X TSS Concentration (Mg/L) X 8.34 If we determine the concentration of solids in Mg/L of VSS, the calculation would be the same except we substitute the VSS concentration for the TSS concentration. WebThus, if one-third of the solid matter contains fixed soils at a specific gravity of 2.5 and two-thirds of the solid matter consist of volatile soils with a specific gravity of 1.0, the overall specific gravity would be: or S s = 1/0.802 S s = 1.25 Now if sludge consist of 10 % solids, i.e. 90 % water, using above equation gives: or S sl = 1/0 ...
