Sample mixtures of simulated sludge, monosodium titanate (MST), crystallized silicotitanate (CST, grounded or ungrounded), and simulated salt solution will be prepared in varying ratios and treated to temperatures of up to 60 degrees Celsius for varying settling times. After treatment, particle size distribution of the material will be analyzed; physical properties including bulk density and pH will be measured. The Analytical Development group will analyze particle size distribution of the material and will also examine the material using Scanning Electron Microscope (SEM).
