Definition - What does Solids Concentration mean?
Solids Concentration is the volume of solids in a liquid divided by the total volume of the solution. It is one of the most important parameters in solid/liquid separation. Solids concentration has a major influence on the numerical values of some of the other constituent terms required for equipment modelling. For example, the resistance of a fluid to flow during filtration increases with increase in solids concentration.
Petropedia explains Solids Concentration
When the density of slurry in a hydrocarbon solution needs to be determined, the concentration of solids by weight in the slurry should be known. Thus, the solid concentration in a solution is an important factor. The density of the slurry is inversely proportional to the solids concentration. The formula for calculating slurry density is as follows:
ρm = 100 / [cw / ρs + [100 - cw] / ρl]
ρm = density of slurry (lb/ft3, kg/m3)
cw = concentration of solids by weight in the slurry (%)
ρs = density of the solids (lb/ft3, kg/m3)ρl = density of liquid without solids (lb/ft3, kg/m3)
