Client Background
The client is a local government authority responsible for urban wastewater treatment infrastructure. The wastewater treatment plant serves municipal sewage and requires stable, compliant, and efficient solid–liquid separation to meet discharge standards.
Challenge
The treatment plant faced the following challenges:
High requirements for coagulation efficiency and stability
Strict control on product quality and insoluble matter
Variable wastewater characteristics requiring flexible flocculation solutions
Need for reliable chemicals suitable for government-operated facilities
Solution Provided
We supplied a customized coagulation and flocculation package, combining high-purity PAC with application-specific PAM products.
Solution Highlights
High Al₂O₃ PAC ensured strong and fast coagulation
Low insoluble content supported clean operation
APAM enhanced floc formation and sedimentation
CPAM improved sludge conditioning and dewatering
Implementation & Technical Support
PAC was applied at the primary coagulation stage
APAM and CPAM were dosed at different process points based on sludge characteristics
Technical guidance supported correct dosing and smooth commissioning
Results Achieved
After implementation, the wastewater treatment plant achieved:
Efficient removal of suspended solids
Improved clarification performance
Stable sludge settling and dewatering
Reliable compliance with wastewater discharge standards
Why This Solution Worked
Product specifications precisely matched treatment requirements
Integrated coagulation–flocculation approach improved overall efficiency
Stable product quality met government procurement standards
