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

Proper water quality is essential for the preservation of the natural habitats of fish, insects, birds and plant communities. Chloride levels in sewage treatment plants are kept under control in order to protect surface waters and groundwater from harmful pollutants.

Chloride is essential for the development of aquatic habitats, but high levels of chloride have negative effects on an ecosystem. High chloride levels degrade water quality, increase species mortality, and alter ecosystem characteristics.

In particular, sewage sludge or biological solids remaining from treatment systems also contain chloride. The chloride standard for sewage treatment ponds in general is 230 milligrams per liter.

The main standards based on the determination of chloride in the 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: Single-use for materials with a liquid solids ratio of 10 l/kg and a particle size of less than 10 mm (reduced or not reduced) phased party experiment
• SM 4500-Cl Chloride

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 chloride determination (TS EN 12457-4) services.
