Polyacrylamide Uses in Textile Industry for Wastewater Treatment
Introduction
The textile industry is one of the largest water-consuming industrial sectors in India. Textile dyeing, washing, bleaching and processing plants generate huge amounts of wastewater containing dyes, suspended solids, chemicals, starch, surfactants, salts and organic pollutants. Treating this wastewater efficiently is one of the biggest challenges for textile manufacturers.
Polyacrylamide is widely used in textile wastewater treatment plants because of its excellent flocculation, clarification and sludge dewatering properties. Textile industries use different grades of Polyacrylamide chemicals to improve settling speed, reduce sludge moisture, increase filter press efficiency and lower overall treatment cost.
Micro Polymer Industries is a trusted Polyacrylamide manufacturer, importer & bulk supplier in India providing high-performance Anionic, Cationic and Nonionic Polyacrylamide chemicals for textile ETP plants across Ahmedabad, Gujarat and Pan India. Polyacrylamide also known as Polyelectrolyte.

What is Polyacrylamide?
Polyacrylamide (PAM) is a water-soluble polymer widely used as a flocculant in industrial wastewater treatment processes. It helps bind suspended particles together and forms larger flocs that settle quickly.
The textile industry mainly uses Polyacrylamide for:
- Wastewater clarification
- Sludge dewatering
- Color removal support
- Suspended solids removal
- Filter press applications
- Water recycling systems
Why Textile Industries Use Polyacrylamide
Textile wastewater contains:
- High TSS (Total Suspended Solids)
- Dye particles
- COD & BOD load
- Oil & grease
- Fibers & lint
- Chemical residues
Without proper treatment, this wastewater can create operational and environmental problems.
Polyacrylamide improves treatment efficiency by increasing settling speed and improving sludge separation.
Types of Polyacrylamide Used in Textile Industry
Anionic Polyacrylamide
Anionic Polyacrylamide is mainly used for clarification and suspended solids settling.
Best Applications:
- Primary clarifier
- Chemical settling tank
- Color removal process
- Inorganic wastewater treatment
Major Benefits:
- Faster settling
- Better water clarity
- Reduced turbidity
- Improved floc size
Cationic Polyacrylamide
Cationic Polyacrylamide is commonly used for sludge dewatering applications.
Best Applications:
- Belt filter press
- Screw press
- Centrifuge dewatering
- Sludge thickener
Major Benefits:
- Strong sludge cake formation
- Lower sludge moisture
- Better filter press efficiency
- Reduced sludge disposal cost
Nonionic Polyacrylamide
Nonionic Polyacrylamide is used in special wastewater conditions where charge sensitivity is low.
Applications:
- Acidic wastewater
- Low charge wastewater
- Specialty textile processing plants
Common Problems in Textile Wastewater Treatment
Textile ETP plants commonly face:
| Problem | Impact |
|---|---|
| Slow settling | Overflow water becomes dirty |
| High sludge moisture | Disposal cost increases |
| Poor floc formation | Clarification efficiency drops |
| Excess chemical consumption | Operating cost increases |
| Filter press choking | Production downtime |
| Color carryover | Water quality issues |
Polyacrylamide helps solve these problems effectively.
Polyacrylamide Applications in Textile ETP Plant
Primary Clarification
Polyacrylamide improves suspended solids settling in clarifiers and settling tanks.
Sludge Dewatering
Textile sludge usually contains fibers, dyes and organic solids. Cationic Polyacrylamide helps reduce sludge moisture.
Filter Press Operation
Polyacrylamide improves cake formation and increases filtration speed.
Color Removal Support
Used along with decoloring chemicals and coagulants for dye removal applications.
Water Recycling Systems
Improves treated water quality for reuse applications.
How Polyacrylamide Works in Textile Wastewater
Polyacrylamide acts as a bridging polymer between suspended particles.
Mechanism
Fine Particles+ Polymer Bridging→ Heavy Settling Flocs
These larger flocs settle rapidly and separate solids from water efficiently.
Polyacrylamide Selection Guide for Textile Industry
Choosing the correct Polyacrylamide grade is extremely important.
Key Selection Factors
Wastewater pH
Different polymer grades perform differently at various pH ranges.
Dye Type
Reactive, direct and disperse dyes behave differently.
Sludge Characteristics
Organic sludge generally requires Cationic PAM.
Dewatering Equipment
Different equipment may require different molecular weights.
Polyacrylamide Dosage Guide
Correct dosage is critical for effective performance.
Standard Solution Preparation
Most textile industries prepare:
- 0.1% solution
- 0.2% solution
- 0.5% solution
- 1% solution
