Determination of Treatment Sludge Fluoride (TS EN 12457-4)

In the early stages of industrialization, wastewater and sewage were left to streams without much treatment. However, as the population increased, the streams could not cope with these polluted waters. The deterioration of water quality is a serious concern. This is why waste water treatment systems are needed. However, these studies have started to create sewage sludge this time. What remains from purification systems is a dilute solid suspension. These solids are called sewage sludge. These solids are now called biological solids.

Sewage sludge also contains fluoride. Fluoride is the ion form of the dissolved element fluorine that can form compounds with other elements. Fluorine is an essential element found in different proportions in plants and animals and necessary for life.

The main standards based on fluoride determination in treatment sludge carried out in advanced laboratories are as follows:

• EN 12457-4 Waste characterization - Solid extraction analysis - Suitability test for solid extraction of granular solid wastes and sludges - Part 4: One-stage batch test for materials with a liquid solids ratio of 10 l/kg and a particle size of less than 10 mm (reduced or not reduced)
• SM 4500-F Fluoride

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 treatment sludge fluoride determination (TS EN 12457-4) services.
