Project Background

A municipal wastewater treatment plant in Brazil was facing challenges in sludge dewatering efficiency and solid–liquid separation performance. Due to increasing treatment volumes and stricter environmental discharge standards, the plant was seeking a more efficient and cost-effective flocculant solution.

Solution Provided

Jiangsu Hengfeng Fine Chemical Co., Ltd. supplied a cationic polyacrylamide (CPAM) specially designed for municipal wastewater and sludge treatment. Based on the customer’s water quality characteristics, laboratory jar tests were conducted to evaluate flocculation performance and optimal dosage.

Application Process

The cationic polyacrylamide was applied in the sludge conditioning stage before mechanical dewatering. During on-site testing, the product demonstrated rapid floc formation, strong floc structure, and excellent settling performance.

Results & Performance

The test results showed significant improvements:

Faster sludge settling and clearer supernatant

Improved sludge dewatering efficiency

Reduced moisture content in dewatered sludge cakes

Lower chemical consumption compared to previous flocculants

The customer confirmed that our cationic polyacrylamide met their operational requirements and achieved stable, reproducible performance under real operating conditions.

Customer Feedback

After successful testing, the municipal wastewater treatment plant expressed strong satisfaction with the product performance and technical support provided. The solution proved to be reliable for continuous operation and suitable for large-scale municipal wastewater treatment applications.
