Introduction
To remove TSS from water—total suspended solids—coagulation and flocculation represent the most proven, cost-effective treatment approach. Suspended solids include silt, clay, organic matter, algae, and industrial particulates that cause turbidity and carry pollutants. PAC (poly aluminium chloride) destabilizes negatively charged colloids, while PAM (polyacrylamide) bridges micro-flocs into large, settleable aggregates. Typical TSS removal rates exceed 90% when coagulant-flocculant dosing is optimized through jar testing. For high-TSS wastewater from mining, construction, or paper mills, sedimentation basins or dissolved air flotation (DAF) cells follow chemical conditioning. Effluent TSS below 10 mg/L is achievable in well-designed systems. Factors affecting performance include particle size distribution, zeta potential, pH, and mixing energy. This guide explains how to remove tss from water systematically—covering coagulant selection, dosing protocols, settling optimization, and monitoring strategies for consistent compliance.
Primary Causes
- Industrial process discharge
- Raw material carryover
- Incomplete biological treatment
- Equipment malfunction
- Seasonal variations
Treatment Methods Comparison
| Method | Removal | Capital Cost | Op Cost | Best For |
|---|---|---|---|---|
| Coagulation (PAC) | 30-55% | Low | Medium | Suspended matter |
| Biological | 70-95% | Medium | Low | Biodegradable |
| AOP (Fenton) | 50-80% | Medium | High | Refractory |
| Activated Carbon | 20-80% | Low | High | Polishing |
Recommended Treatment Train
- Coagulation: PAC 50-300 mg/L
- Biological: Aerobic/anaerobic
- Advanced: Fenton or activated carbon
- Polishing: Filtration + disinfection
Chemical Dosing Guide
| Stage | Chemical | Dosage | pH | Efficiency |
