Sludge Hazardous Waste Testing Center

Both in daily life and industry, a certain amount of sludge is generated, which is hidden in water and commonly found in some sewage. Nowadays, there are many types of sewage, and for the sake of our physical health, it is necessary to conduct testing on some sludge.

Sludge Hazardous Waste Testing CenterSludge usually refers to the general term for various solid sediments and floating objects generated during sewage treatment, which generally contain a large amount of toxic and harmful substances. Untreated sludge discharged into the environment can easily cause soil and other environmental pollution problems. Therefore, conducting sludge testing is of great significance in guiding sludge treatment.

Classified by source: domestic sewage sludge, industrial wastewater sludge, and water supply sludge, etc;

According to the treatment method and separation process, it can be divided into: initial sedimentation sludge, humic sludge, concentrated sludge, etc;

According to the composition and properties of sludge, it can be divided into organic sludge and inorganic sludge, hydrophilic sludge and hydrophobic sludge, etc.

Sludge Hazardous Waste Testing CenterMeasurement range of sludge moisture content

Domestic sludge, sedimentation tank sludge from sewage treatment plants, reservoir sludge, bottom sludge from aquaculture water bodies, activated sludge, humic sludge, river sludge, industrial sludge, water supply sludge, concentrated sludge, etc.

Measurement project for sludge moisture content

Moisture content detection, toxic substance detection, plant oxygen content detection, solid content detection, volatile matter and ash content detection, fertility detection, pH， Heavy metal content, component testing, pesticide residue testing, bisphenol A, nonylphenol, etc.

What are the regulations for mud testing indicators

1. Microorganisms: The types and quantities of microorganisms in sludge will show significant changes after digestion and composting treatment, especially before greening, agriculture, and other treatments, which require detection of pathogenic microorganisms.

2. Volatile substances and ash content: Volatile substances represent the amount of organic impurities contained in sludge, while ash content represents the amount of inorganic impurities contained in sludge.

3. Toxic substances: In order to avoid environmental impact, it is necessary to detect toxic substances such as mercury and lead in sludge and its products.

4. Moisture content and solid content: Sludge with high moisture content has low solid content, while sludge with low moisture content has high solid content. The remaining sludge undergoes concentration, digestion, and dewatering treatment, and the moisture content of the dewatered sludge will significantly change. Changes in moisture or solid content can reflect the effectiveness of the concentration, digestion, dewatering, and other treatment processes.
