Total Suspended Solids (TSS) Testing in Water

Overview: Total suspended solids (TSS) testing measures the concentration of suspended particles in water. It is used to monitor discharge quality, assess treatment efficiency and help prevent fouling and compliance issues.

BJL Laboratoires performs TSS analysis to assess the particulate load in water, support discharge monitoring and optimise water treatment processes. This parameter helps assess regulatory compliance and the performance of treatment facilities.

What Are Total Suspended Solids?

Total suspended solids (TSS) refers to the concentration of solid particles suspended in water. These may include sludge particles, fine sand, organic matter and mineral particles. TSS is an indicator used to assess water quality and the potential impact of suspended particles on equipment and treatment processes.

Why Measure Suspended Solids?

• Quantify the particulate load in water
• Check compliance with applicable discharge requirements
• Monitor treatment efficiency, including settling and filtration
• Investigate issues such as clogging, turbidity and changes in process performance
• Optimise operating and maintenance costs

When Is TSS Testing Needed?

• Monitoring wastewater or industrial effluent discharges
• Assessing wastewater treatment plant performance
• Monitoring stormwater
• Testing wash water and process water
• Investigating equipment or treatment system malfunctions

Which Types of Water Can Be Tested?

• Municipal and industrial wastewater
• Stormwater
• Surface water
• Process water and rinse water
• Water from treatment facilities

How Is TSS Analysis Performed?

• Collection of grab or composite samples
• Laboratory filtration
• Determination of the mass of retained solids
• Calculation of the suspended solids concentration
• Preparation of an analytical report to support decision-making

A Service Tailored to Operational Needs

• Sampling advice tailored to your monitoring or investigation objectives
• Traceability of samples and analytical conditions
• Clear results to support timely decisions
• Results interpretation and support for process optimisation

Frequently Asked Questions About TSS

What does TSS mean in water testing?
TSS stands for total suspended solids: the concentration of solid particles suspended in water, expressed in mg/L.

Why is TSS important?
Suspended solids affect water quality, treatment performance and compliance with applicable discharge requirements.

What problems can high TSS levels cause?
High suspended solids levels can contribute to clogging, increase the load on settling and filtration systems, and lead to non-compliant discharges.

When should TSS be measured?
During discharge monitoring, treatment performance assessments or investigations into operational problems.
