The centrifugal settling, expression, differential scanning calorimetry (OSC), and drying tests are employed for measuring the bound water content in a sludge made of CaCO 3 , PYC, or glass powders, an inorganic Cu(OH) 2 sludge, and an activated sludge. The bound water is found to be an operationally defined value that differs greatly when different measurement technique is applied. A classification scheme for dividing the moisture content in a sludge based on the bound water data is proposed.
