Alternatively, the sonicated sludge may be recycled into an aeration tank as substances for microorganisms to achieve 60%-100% of sludge reduction in low-sludge wastewater treatment processes [7, 9]. raychem rtd7alWebbHigh-density sludge treatment process. Removal of the solids is accomplished in large mechanical thickeners. The achievement of high sludge solids, reported by Bethlehem to be as great as 50%, is dependent upon the ferrous-to-ferric iron ratio. If ferric iron dominates this ratio, sludge densities may be limited to 20% solids. raychem rpg thailandWebbAnd Volume Flow rate can be expressed as Q= volume/time= v/t Eq2. From Eq (1), mass/volume x volume/time Eq3. Now, mass/volume=Fluid density ρ. And volume/time = Volumetric Flow Rate=Q. From Eq (3) , ṁ = ρ.Q Eq4.
