Determination of Ignition Loss of Dry Mass in Sewage Sludge

The determination of the heating loss of the dry mass in the treatment sludge is carried out within the scope of the following standards.

• TS EN 15169 Waste characterization - Determination of combustion loss in waste, sludge and sediment
• TS EN 12879 Properties of sludges - Determination of the dry mass's glow loss

Ignition loss or loss on ignition (LOI) refers to the process of measuring the change in weight of a sample after heating at high temperature, which causes some of its content to burn or evaporate. During the heating process, the weight change in the sample is monitored and this determines the organic matter content in substances such as sediment, sludge, soil and waste.

The percent weight lost on firing gives a rough measure of the organic content of the dry mass. In general, percent loss in ignition values shows an inverse relationship with percent dry weight values.

Treatment sludge formed by the treatment of domestic and industrial wastewater should be sent to landfills or disposal facilities. However, beforehand, it is necessary to determine whether these wastes are dangerous or not. Hazardous wastes should be sent to disposal facilities and non-hazardous wastes should be sent to landfills.
