As part of our operations, we generate ETP sludge waste after recycling production water. To ensure responsible utilization, we are collaborating with a cement factory that intends to test the use of dried ETP sludge as fuel. During this testing phase, we require measurement of VOC pollutant levels emitted from the chimney. Kindly confirm if you can conduct this test. If yes, please provide us with a quotation and details of the testing procedure.
One of our highly proficient and ISO certified laboratory would be taking over this job.

Enquiry: I would like to inquire whether your laboratory offers a test to determine the size distribution of suspended solids in water, particularly to identify and quantify particles larger than 120 microns.
The purpose of the analysis is to determine the concentration and size of suspended particles, especially those exceeding 120 µm, so that we can select the most suitable filtration system.
Could you please let me know if your laboratory provides this type of analysis or any equivalent test? If available, I would appreciate it if you could also share the sample requirements, turnaround time, and quotation.
Thank you for your time and assistance. I look forward to your response.

TBC (Total Bacterial Count) and Legionella testing are two different types of microbiological water tests, each serving a different purpose.
1. TBC (Total Bacterial Count)
Also called:
Total Viable Count (TVC)
Heterotrophic Plate Count (HPC)
Purpose: Measures the total number of viable bacteria present in a water sample. It does not identify specific bacteria or indicate whether they are harmful.
Common uses:
Drinking water quality monitoring
Process water testing
Cooling towers
Hospital water systems
Food and beverage industries
Typical method:
Plate Count Agar (PCA) or similar media
Incubation at specified temperatures (commonly 22°C and/or 36–37°C) for defined periods
Results reported as CFU/mL (Colony Forming Units per milliliter)
Interpretation:
Low counts generally indicate good microbiological quality.
High counts may suggest poor sanitation, biofilm formation, or stagnation, but they do not necessarily indicate the presence of pathogens.
2. Legionella Testing
Purpose: Detects and quantifies bacteria of the genus Legionella, particularly Legionella pneumophila, which can cause Legionnaires’ disease.
Common sources tested:
Cooling towers
Hot and cold water systems
Hospitals
Hotels
Spa pools
Decorative fountains
Testing methods:
Method
Detects
Time to Result
Culture (ISO 11731)
Live Legionella
7–10 days
qPCR
Legionella DNA
Few hours to 1 day
Rapid antigen tests
Specific targets
Minutes to hours (limited use)
Results:
Reported as CFU/L for culture methods.
qPCR results are typically reported as genome copies per liter or similar molecular units, depending on the laboratory.

Why both tests are often performed
A water system can have:
Low TBC but detectable Legionella, or
High TBC but no Legionella.
Because of this, TBC cannot be used to confirm or rule out the presence of Legionella. For systems with a risk of aerosol generation (such as cooling towers, healthcare facilities, hotels, and large building water systems), Legionella testing should be performed separately as part of a water safety management program.
If you’re working with a particular standard (such as ISO, WHO guidance, ASHRAE, or local regulations), the testing frequency and action limits may differ. I can also explain the relevant requirements for those standards.
