Measurement of bound water in sludges: A comparative study
Abstract:The centrifugal settling, expression, differential scanning calorimetry (OSC), and drying tests are employed for measuring the bound water content in a sludge made of CaCO3, 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.
