A process for the treatment of a solid waste slurry formed from solid waste particles mixed with a liquid includes delivering a solid waste slurry to a first solid-liquid separation means for separating a first amount of the solid waste particles from the slurry, followed by delivering the solid waste slurry from the first solid-liquid separation means to a tank where the solid waste slurry is stirred to maintain the solid waste particles in suspension. The solid waste slurry is then discharged from the tank with a portion of the solid waste slurry being recirculated back to the tank while a second portion of the solid waste slurry is delivered to a second solid-liquid separation means for separating a second amount of the particles from the slurry. Following discontinuation of the stirring of the slurry, the liquid is decanted from the tank at a level above a bottom area of the tank, followed by sampling of the liquid in order to determine the amount of solid waste particles contained in the solid waste slurry. The decanting and sampling may be performed at additional levels within the tank.
