Determination of Electrical Conductivity of Sewage Sludge (TS ISO 11265)

Determination of Electrical Conductivity of Sewage Sludge (TS ISO 11265)

The ISO 11265 standard, published by the International Standards Organization (ISO), provides an instrumental method for the routine determination of specific electrical conductivity in an aqueous soil substance. Detection is carried out to obtain an indication of the content of water-soluble electrolytes in a soil.

Determination of Electrical Conductivity of Sewage Sludge (TS ISO 11265)

In our country, this standard has been published by the Turkish Standards Institute (TSE) with the following title: TS ISO 11265 / Cor.1 Soil quality - Determination of electrical conductivity.

The main substances that make up the treatment sludge are:

  • Both inorganic and organic materials
  • Large concentrations of certain plant nutrients
  • Numerous trace elements in much smaller concentrations
  • organic chemicals
  • from some pathogens

The compositions of sewage sludges vary considerably depending on the wastewater composition and the treatment processes used. The concentrations of trace metals and other pollutants in sewage sludge have dropped significantly in recent years, especially due to the mandatory industrial pretreatment of wastewater. Most organic chemicals are detected in only a few sludges and are present in very low concentrations. When sludge has higher-than-normal concentrations of trace elements or organic pollutants, their presence is often dependent on a particular sector.

In the test, analysis, measurement and evaluation studies carried out in our organization, national and international standards and applicable legal regulations are complied with and reliable and impartial results are obtained. These studies are based on the latest technological equipment, trained and experienced staff and modern methods. Among the numerous tests carried out in this context, there are also electrical conductivity determination of sewage sludge (TS ISO 11265) services.
