Sludge Testing
Sludge, a byproduct of wastewater treatment processes, encompasses a complex mixture of organic and inorganic materials. Proper analysis of sludge is essential for environmental compliance, resource recovery, and sustainable waste management. Our laboratory offers in-depth sludge testing services tailored to meet the diverse needs of industries and municipalities

Why Sludge Testing Matters
Understanding the composition of sludge is crucial for:
- Environmental Protection: Preventing soil and water contamination by identifying hazardous constituents.
- Regulatory Compliance: Meeting local and international standards for waste disposal and treatment.
- Resource Recovery: Identifying valuable components for potential reuse or energy generation.
