Project Overview
A municipal water treatment plant located in Southeast Asia provides drinking water purification services and wastewater treatment solutions for local communities.
With increasing population growth and stricter environmental requirements, the existing treatment system faced higher operational demands:
- Fluctuating raw water turbidity
- Increased suspended solids during rainy seasons
- Difficult removal of colloidal particles
- Unstable treatment performance
To improve purification efficiency and ensure treated water quality meets local environmental and water supply standards, the plant was looking for a safe, efficient, and reliable coagulant.
After technical evaluation and sample testing, KolinSC recommended:
High-performance Poly Aluminium Chloride (PAC) as the primary coagulant.
Customer Challenges
The municipal water treatment process faced several challenges:
1. Raw Water Quality Fluctuation
Seasonal changes, rainfall, and source water conditions caused variations in turbidity and suspended solids levels, requiring a highly adaptable coagulant.
2. Difficult Removal of Fine Particles
Small colloidal particles remained stable in water and were difficult to remove through conventional sedimentation.
3. Higher Treatment Efficiency Requirements
With stricter environmental standards, the plant needed to improve treatment efficiency while maintaining stable water quality and controlling operating costs.
Our Solution
Based on the actual operating conditions of the water plant, KolinSC provided a professional PAC application solution.
Step 1: PAC Coagulation
After adding PAC into raw water:
- Particle charges were effectively neutralized
- Stable colloidal systems were destabilized
- Impurities aggregated into larger flocs
Step 2: Sedimentation Separation
After effective coagulation, larger flocs were formed and removed through sedimentation processes.
Step 3: Operation Optimization
KolinSC provided:
- Product selection recommendations
- Dosage optimization
- Application technical support
to help maintain stable treatment performance.
