dry solids content at 105C. The total solids content is expressed as a ratio of weights obtained before and after the drying process. The test protocol consists of placing a sludge sample (25 to 100 mL depending on the sludge concentration) in an oven at a temperature of 105 C until a steady mass is obtained.

Drying foods in a vacuum oven therefore has a number of advantages over conventional oven drying techniques. If the sample is heated at the same temperature, drying can be carried out much quicker. Alternatively, lower temperatures can be used to remove the moisture ( e.g. 70 o C instead of 100 o C), and so problems associated with degradation ...
