Project Overview
A municipal wastewater treatment plant located in Southeast Asia processes a large amount of domestic wastewater and industrial mixed wastewater every day.
With increasing treatment capacity, sludge production continued to grow, creating significant pressure on the existing sludge management system:
- High sludge moisture content
- Poor sludge settling performance
- Low dewatering efficiency
- Increasing transportation and disposal costs
The wastewater plant was looking for an efficient and reliable flocculant to improve sludge thickening and dewatering performance while reducing operational costs.
After sludge sample testing and application evaluation, KolinSC recommended:
High-performance Polyacrylamide (PAM) as a specialized sludge dewatering flocculant.
Customer Challenges
Sludge treatment faced several major challenges:
1. High Sludge Moisture Content
Untreated sludge contains a large amount of water, resulting in:
- Large sludge volume
- Difficult transportation
- High disposal costs
2. Fine Sludge Particles
Sludge particles carry surface charges, causing mutual repulsion and preventing effective aggregation.
3. Limited Dewatering Equipment Performance
Weak sludge flocs resulted in:
- Lower filtration efficiency
- Reduced centrifuge performance
- Higher cake moisture content
Our Solution
Based on sludge characteristics and treatment conditions, KolinSC provided a customized PAM flocculation solution.
Step 1: Sludge Analysis
Sludge samples were evaluated based on:
- Solid content
- Charge characteristics
- Settling performance
to select the most suitable PAM type.
Step 2: PAM Flocculation Treatment
After PAM addition:
- Polymer chains adsorbed sludge particles
- Larger flocs were formed
- Solid-liquid separation was accelerated
Step 3: Dewatering Process Optimization
After PAM treatment:
- Filtration performance improved
- Dewatering efficiency increased
- Final sludge moisture content decreased
