Industrial Water & Waste Water Quality Monitoring
Industrial Water and Wastewater Quality Analysis is the process of sampling, testing, and evaluating water used and discharged by industrial facilities to determine its suitability for use or compliance with environmental regulations.
- It involves assessing physical, chemical, and biological parameters to:
- Ensure water used in processes meets quality needs (e.g., boiler feed, cooling towers)
- Confirm wastewater is treated adequately before being released or reused
- Detect pollution or potential harm to ecosystems and human health
Types of Water Analyzed in Industrial Sector
|
Type |
Purpose |
|
Raw Water |
Source water before any treatment (e.g., river, well) |
|
Process Water |
Used during manufacturing or chemical processes |
|
Cooling Water |
For equipment or reactor cooling |
|
Boiler Feed Water |
Must be low in dissolved solids and gases |
|
Treated Wastewater |
Must meet discharge standards or reuse criteria |
|
Effluent / Discharge |
Final water released to environment or sewer |
Sample Collection for Water Audit

Key Parameters in Industrial Water & Wastewater Analysis
|
Category |
Parameters Analysed |
|
Physical |
Temperature, Colour, Odor, Turbidity, Total Suspended Solids (TSS) |
|
Chemical |
pH, Total Dissolved Solids (TDS), COD, BOD, Oil & Grease, Heavy Metals, Chlorides, Sulphates |
|
Biological |
Fecal Coliforms, Pathogens (in effluent) |
|
Industry-specific |
Cyanide, Phenols, Fluoride, Ammonia, Phosphates, etc. (depending on process) |
Why it’s important to do Water and Waste Water Analysis:
Performing wastewater quality analysis involves a structured process of sample collection, testing, analysis, and reporting to assess the condition of the wastewater and its impact on treatment processes, the environment, or regulatory compliance.
- Environmental Protection – Prevents contamination of water bodies
- Process Optimization – Ensures equipment efficiency and product quality
- Regulatory Compliance – Aligns with norms like CPCB, EPA, ISO 14001, ZLD, etc.
- Water Reuse & Recycling – Supports sustainable water management

Steps to Perform Wastewater Quality Analysis
Activity |
Purpose |
|
Define Objectives |
Determine why you’re testing: compliance, process control, reuse, etc. |
|
Select Sampling Points |
Inlet (raw sewage), intermediate (bioreactor), outlet (treated effluent). |
|
Choose Sampling Method |
Grab, composite, time- or flow-proportional, depending on variability. |
|
Sample Collection |
Use clean, labelled containers; preserve samples (cooling/chemicals). |
|
Conduct Testing |
On-site for quick parameters, send to lab for advanced tests. |
|
Analyze Parameters |
Physical (TSS, Temp), Chemical (BOD, COD, pH), Biological (Coliforms). |
|
Interpret Results |
Compare with national discharge standards (e.g., CPCB, EPA). |
|
Report Findings |
Document results, include deviations, trends, and recommendations. |
|
Take Corrective Actions (if needed) |
Improve treatment process or re-test in case of non-compliance. |
Common Parameters to Analyze

Standard Methods Used
- APHA Standard Methods for the Examination of Water and Wastewater
- BIS IS 3025 Series (India)
- EPA Test Methods (US)
- ISO 5663 for Sampling Techniques
Tips for Effective Analysis
- Calibrate instruments before use
- Follow sampling SOPs and use preservative agents
- Test BOD within 6 hours of sampling
- Maintain a chain of custody log
- Use certified labs for regulatory reporting
