Treatment Sludge Analysis

Environmental Impacts of Sewage Sludge

Sewage sludges are concentrated deposits of pollutants and harmful substances in water. If not treated properly, these sludges can cause major damage to the environment. These harmful effects can be:

Soil Pollution: Heavy metals and toxins in sewage sludge can leach into the soil, reducing the productivity of agricultural land and disrupting ecosystem balance.
Water Pollution: Sludge leaching into water bodies can cause water contamination. This contamination threatens the survival of aquatic life and can reduce water oxygen levels.
Air Pollution: Sludge, especially untreated sludge, can release harmful gases such as methane gas. These gases can create global warming and air quality problems.

Importance of Treatment Sludge Analysis

By determining the sludge content, sewage sludge analysis helps us understand what types of pollutants are present and what processes can be used to safely dispose of the sludge. The main purposes of these analyses are:

Identification of Chemical Constituents: Heavy metals (e.g. lead, mercury, cadmium) and other hazardous chemicals may be present in sewage sludge. Identification of these chemicals helps to determine the correct treatment methods by assessing the impact of the sludge on the environment.
Assessment of Biological Activity: Sewage sludge can sometimes contain pathogenic microorganisms. The presence of such microorganisms indicates that the sludge must be biologically treated before it can be safely disposed of.
Determination of Physical Properties: Determination of physical properties of sludge, such as density, moisture content and textural structure, is necessary to determine processing and disposal methods.
Measuring the Degree of Contamination: Determining the level of organic and inorganic pollutants in sewage sludge determines which treatment methods will be used and in which area the sludge can be used.

"Treatment Sludge Analyses" carried out within the scope of environmental legislation are carried out for the recycling or disposal of waste and treatment sludge from industrial enterprises.

Related legislation for "Sewage Sludge Analysis":
- Regulation on the Use of Domestic and Urban Sewage Sludge in Soil

In our laboratories serving in many parts of Turkey, "Treatment Sludge Analyses" are carried out in accordance with legal regulations and standards related to TÜRKAK accreditation and authorization by the Ministry of Environment.
